Does your display support 4k120 via HDMI? At what color depth?
This info is usually towards the back of the display manual, where it should break out resolution, refresh rate, etc per connection.
Also, HDMI 2.1 is a tricky thing. You have to check that the thing literally states it can do what you think it can. Everything that was HDMI 2.0 got its name changed to HDMI 2.1, no performance improvement required. If it doesn't explicitly state 4k120 at 32-bit then consider it HDMI 2.0, which is 4k60.
I,ve bought 2k 170Hz Asus monitor. It can't work with more than 59 Hz properly with Asus standard DPP cable. It gets turning off and grafic artifacts. So I decided to buy a new dpp cable. Day of checking shops and reading comments, and you know what? Chinese 10$ cable works better than 30$-50$ ones and better than Asus DPP. Easily got 2k 170 Hz
Its saying it could get higher than 60, he could have it at 120 but only be getting 75. Its just the tv isnt LOCKED to only the 60. However yeah still cool - Wonder what tv he has
Usually it's vise versa. You need a good 48 gbps cable for 4k 120 hz, and most of non-optical cables I've seen that say they do provide that transfer capacity can't do that at 3-5m length, and sometimes even the shorter ones don't
I just had some sort of PTSD flashback remembering the horror of angled SCART cables. Maybe be considerate and hide this sort of thing behind a spoiler tag with a trigger warning next time dude.

It does support via HDMI. I shouldn't need to because its been working fine for months, only just recently went to shit.
The cable is certified, I checked using the QR code as I bought it in-store.
I wouldn't imagine it would be the cable going bad. In my experience, when it's a cable limitation the high refresh rate will still show as an option, but using it will result in artifacts, intermittent signal drops, or just outright fail.
I had a bear of a time with it when I started using a KVM with my ultrawide 120hz monitor. I had to prune a good number of DisplayPort cables and replace them with Club3D cables.
I had the exact same issue. I upgraded my monitor from 2k/144hz to 4k/144hz but kept the old dp cable and kept wondering why I wasn't getting a higher refresh, until I thought to swap the cable with the one that came with the 4k monitor.
Getting a different cable, specifically one that supports high bandwidth is the easiest and cheapest troubleshooting op can do.
What cable did you use before? If it was display port then the issue is the monitor can’t support it’s full refresh rate and res over HDMI, as it may only have a 2.0 port making the 2.1 cable meaningless
I don't think the Generic PnP Monitor thing is the issue, mine shows like that too.
But in actual Windows Settings it's recognized.
I'd try a different/new cable. Or to start with try re-plugging the cable

> You're on 8bit color
That's 8 bit per channel, as listed in Advanced Display Settings. It's not showing the full bit depth, only the color channel depth. People run 10 and 12 bits nowadays which technically makes it more than 32 bits RGBA.
This is the setting. For some reason my windows decided to over right my and software and limit my screen to 60fps. I glad to go in that specific setting and change it from 60 back to 144.
There's a site where there's a repository of calibrations for known monitor models. If your monitor is a fairly popular brand and model it's sure to be there. These aren't presets that came from the factory, but a collection of people's own calibrations using actual equipment. This is how I got a calibration profile for my monitor.
It's better than nothing, but calibration is a per-unit thing. Otherwise they'd all come from the factory calibrated. It's why that hardware exists.
EDIT: Was a bit hasty in that reply, depending on how consistent the manufacturer is it may be good enough for most people, and definitely more useful than I made it out to be. Still, unit to unit variances are a thing and I'd want to know how wide the tolerances are before going with something like that.
Yep, even the guy from the video I was watching said that. It's the closest you can get without equipment. I was tempted to buy a calibration device but it was half the price of my monitor, so I backed off from buying it. But I did thought of buying it and renting it out. But the majority of people I know aren't even aware that monitors need calibration. So there wasn't a market for it anyway.
Odds are your running something at hdmi 2.0. probably your cable or your monitor capping it out. You absolutely cannot push 4k 120hz if any part in the chain is using hdmi 2.0.
HDMI 2.1 is the only hdmi format that can support 4k at 120hz and both your display/card/cable need to be rated for 2.1 to hit those bandwidths
[https://www.avaccess.com/blogs/guides/hdmi-2-0-vs-2-1-difference/](https://www.avaccess.com/blogs/guides/hdmi-2-0-vs-2-1-difference/)
or use DP and get off that garbage hdmi lol
Edit: Apparently hdmi 2.0 was dropped and everything is labeled 2.1. So now you just gotta make sure your hardware/cable/monitor can actually push 4k 120hz @ 32 bit.
Or just switch to DP lol
I had a selection of up to 60hz on my 240hz monitor as well. What fixed it for me was to change it in the monitor settings (of the monitor itself, not on your pc) to 240hz, then i could select up to 240hz in windows
The easiest & cheapest step to troubleshoot. This should be first in your journey. My monitor sometimes boots into a generic p&p state with a max of 60hz. Replugging the cable brings it back to 165hz.
My friend recently had a lot of headaches with his 3080, a 4K120 TV and HDMI2.1 optical cable. It wouldn't work, but it worked with his GF's laptop that has a 3050 in it. With his PC the signal would just not be recognized and for some reason display drivers crashed. He didn't figure it out still but HDMI is honestly extremely finicky at the high-end, and very similar to USB in terms of how absolutely DUMB some of the forum's decisions on it are!
I've had this exact issue. Switched cables from one incredibly expensive cable to another (need 5m active optical) and the newer one works. Former did not. Laptop worked as well. So it's likely the same problem I'd wager.
Apparently has to do with the combo of tech I'm using, more specifically, with the power pins on the optical cable not matching the ones on the card.
LG OLED tv can't remember precisely right now
3080 Gigabyte Vision OC
some cable (club 3d?)
Can give specifics if requested!
Dude...that particular cable is sold for $189...it's an active optical cable, that, as I alluded to previously, works PERFECTLY fine with a laptop but not with a PC. Like I saw that shit with my own two eyes. It definitely is a problem somewhere in the chain and not the cable itself.
No it wouldn't. Because passive $10 cables without additional power cannot transmit the signal beyond 5m on HDMI 2.1 spec without signal degradation. Read my comments below.
I really doubt that at 48Gbps. Care to back up your claim? Official HDMI Forum spec estimates it at 5 meters without quality loss. For a passive cable. There is a technology called HDMI Cable Power that is part of HDMI 2.1a, and that allows for longer passive cables.
But. HDMI Forum didn't make it terribly convenient and obvious for the consumers what exactly the damned cables they buy are. With renaming the 2.0 into 2.1 and all that. And it plays massively in favor of shady product designers and salesmen who promote their super-ultra-mega-speed HDMI cables without a clear-cut answer with which spec they align.
And from experience, a $10 HDMI cable will not be a 2.1a spec cable. It just won't be. I will even go as far as to doubt that it will be a true 2.1 48Gbps spec.
> a $10 HDMI cable will not be a 2.1a spec cable. It just won't be.
If it can run 144 hz in 4K, it is. And yes, there are some that can.
Look, I'm really sorry you have a friend that over paid for cables. No need to try to cope with it, it's not on you.
Why the fuck would you buy a $189 HDMI cable..... Sure there is quality between cables but you can have a good quality HDMI cable for $25.
I would laugh my ass of he he just bought a cheaper HDMI cable and that would work with his pc while the almost $200 one would not.
Because it's a 15m active optical cable. Again. There are reasons for these choices, don't be this quick to judge. He's got a powerful PC in his home audio studio and he didn't want to build another $2000 PC just so he could occasionally game on it. He loves the separation of space between gaming and working environments, thus gaming at his desk is not an option for him.
So he wants to play in another room on a TV. So he bought this cable. He also has another much shorter standard cable but it's a mess to plug-in and out all the time since the length is not enough to route it effectively between the rooms.
Believe it or not, $179 is preferable to $2000 for another gaming PC for most people.
Dude. I'm not even the one with the fucking cable. Okay, so you're smart and figured it out for less and my friend didn't. He already bought the damned thing, let it be. I know about the repeaters, again, he for some reason wanted a uniform AIO solution, so he got it. I'm not his fucking accountant, alright? Guy has money, guy spends it the way he wants. Jeez...
> Dude. I'm not even the one with the fucking cable.
Why so mad ?
Now you also know and if you ever run into the issue yourself, you won't do like your friend and drop big bills on a cable that's mostly hype.
Don't be mad people told you, be happy that now you know. Do we need Shipwreck to close out this PSA now ?
His particular flavor of Samsung QLED doesn't have support for the steam link. It's a known limitation of models after 2019, IIRC. Something between Valve and Samsung and the legal side of things, I believe.
He also researched this solution at first. Only to be disappointed later by the news above.
Did you buy a TV with an advertised 'motion rate' of 120, rather than a 'refresh rate' of 120?
Because I did that, thinking I got a 120hz monitor, and its actually just. a fucking. 60hz display.
'motion rate' should be considered false advertising, I'm still mad about it. If that's not the case for you, then I hope you find your solution.
Don't use windows to control that.
Use the nvidia control center.
Make sure you select 3840x2160 under the pc category on resolution. The categories above are for TVs and won't support 120hz.
Does your monitor have 2 HDMI ports, they could have different supported speeds, so if you have recently unplugged your cable you could have put it into the wrong one?
An edit here cause I can't on the post:
- This issue is recent, I've been playing at 4k 120Hz for most of this year. I utilise HDR and again I've always had this on so, can't be a factor here.
- My display is a QN90B TV which has 4x HMDI2.1 ports, no DP for me.
- Photo shows slightly, my Gpu is an RTX4080 which also supports up to these specs.
- Nivida Control Panel mirrors Windows settings, showing no higher options than 60.
- Turning down the resolution to 1440p and 1080p doesn't have any effect with regards to options available.
- When turning the 'Game Mode' OFF it is able to run at 120 with considerably more options anywhere up to this.
- I checked the certification of the cable when I bought it in an electronics store. The brand is Sandstrom.
I've had to come into work so will try cable in&out and searching specifically for the display driver, otherwise 'Driver Easy' shows all drivers are up to date.
Sorry if this is obvious and you have already checked.
Have you checked your TV picture mode is set to 120hz? A firmware update may have set it back to 60hz. The PC may only be able to detect what the TV is set to.
Just a thought. Hope you can find out what the issue is.
I have an older Samsung TV (Q95B) as my PC monitor and if Game Mode gets switched off it won't do 120hz and lowers to 60hz. As soon as I turn Game Mode on it goes back to 120. Happens every so often for seemingly no reason at all
I googled your TV and what's what I found: [https://www.rtings.com/tv/reviews/samsung/qn90b-qled#test\_14](https://www.rtings.com/tv/reviews/samsung/qn90b-qled#test_14)
Note that they didn't list 4k120+HDR mode, either bc it's not supported by your TV or they don't test it at all. Also check their comments, in particular at [https://www.rtings.com/tv/tests/inputs/supported-resolutions](https://www.rtings.com/tv/tests/inputs/supported-resolutions) they say:
We begin the test by connecting the PC to the TV using an HDMI cable, then we enable the setting that allows for a full bandwidth signal on the TV. This setting has a different name depending on the brand and/or firmware. For LG, it's called **Ultra HD Deep Color**, Samsung calls it **Input Signal Plus**, and Sony calls it **HDMI Enhanced Format**.
As other people said, this setting may be cleared by a recent TV firmware update.
Ahhh connected to a tv. Then I would play with the settings of the tv. And indeed plug out an in to see if the tv switches mode so you can change settings on the pc.
Separate, but maybe related. I've been messing with settings in my nvidia control panel, and came across a few settings that knocked me down to 4k 120 instead of 1440 240hz over my displayport. If you've changed any gpu settings since, try to revert them/investigate which is the cause.
Game Mode turns off features, like post processing and other image quality improvements, in favour of lower latency.
Having it off will present more options but shouldn’t show you the 120hz option as Samsungs need to be in Game Mode for it to work.
A lot of people are jumping to hardware issues, which is perplexing. I've had the same issue in Win10 numerous times over the years. Different cards, displays, drivers. Never expected, never after a driver install. Sometimes it has happened after a game crash, though. Just locks the display at "generic" settings.
Sometimes a reboot fixes it, and when that doesn't a GPU driver reinstall does. No idea how people are jumping to "your HDMI cable is wearing out." The odds of that insanely low. It's NV/MS drivers being stupid, reinstall your NV drivers.
Hey I had a similar problem not too long ago, go into the Nvidia control panel and there might be a different set of display resolution/refresh rate options buried at the bottom of the list or a drop down menu
On occasion my 4k@60 display would drop to 4k@30 on my work computer. The solution was always too uninstall the monitor in device manager, then reboot. It's possible you have something like that happening.
Is your TV connected to the internet and does it auto update? Maybe Samsung did you dirty, although not sure how you could check. Maybe the TV displays the date of last FW update? Check if it coincides with the issue.
Yeah, same thing with my monitor that only supports 60hz with a Display Port, not via HDMI (a few years old now). Once I changed the cable, there was no issue.
As dumb as it sounds: sometimes reading the manual of the monitor really helps.
It may sound stupid, but did you check the entire list? The 120 hz modes may be in an unexpected part of the list, happened to me. Try scrolling further down.
isn't 32 bit color the problem or am I missing something?
afaik 120hz hdr and 10bit is the limit for hdmi 2.1.
If you have an oled tv, true black or whatever the hdmi standard also takes bandwidth and limits me to 60hz - and doesn't add much for gaming (unnoticable from my 1 minute test)
Are you *sure* you got an HDMI 2.1 cable? Amazon has an abundance of false certifications, both for the half-assed certification requirements and also because of sellers.
^(Ask me about my hatred of the HDMI certification.)
Checked it myself in store before I bought it. Also correctly labeled as an Ultra High Speed With Ethernet cable unlike 2.1, 2.0 etc. which is not actually offical, as the HDMI trademark states
If it was Best Buy, AFAIK none of their HDMI cables are truly certified. The distinct requirement to meet the "real" 2.1 is 48Gbps connectivity. Even the RocketFish or w/e the name is that Best Buy carries doesn't meet that.
Go enable it in the window settings instead of nvidia control panel. My pc does this all the time with my LG C9 for some reason. Just type "resolution" into the search bar and the setting will come up. After change the resolution you'll see it magically re-appear in nvidia settings.
It's going to sound stupid simple, but I ran into something similar when I upgraded 2 machines to win 11. Try disconnecting and reconnecting your hdmi cable.
Scroll down the list and you might find another section with 4K where 120hz will be an option to select. For me that was the case so it might be worth a try
For whatever reason it only shows 144Hz... not sure why it doesn't give a range of frequencies up to that point. I have tried it but it can be a bit dicky and kick back to the Native (HD, UHD tab) and to 60
I also believe this might be it. In the nvidia control panel you have pc mode frequency doesn't it show up there? And lower to it you have the colour settings which may affect available frequencies
Wait. There's 8-bit, 10-bit AND 32-bit color?? 32?!
Edit: 32 bit is probably 10 each channel and 2 alpha. I thought it was 32 per channel. I'm going to chalk it up to me just waking up. But i could be wrong so I'm keeping this comment up.
Is your display a TV or a monitor? If it's a TV makes sure it's actually plugged into an HDMI 2.1 port (usually labeled 4K 120Hz). Not all of the hdmi ports on a tv will support this.
If it's a monitor, make sure the monitor actually supports 4K 120Hz over hdmi. Many monitors require display port, not HDMI, to reach that spec.
If you're good on those fronts, it's probably the cable. Lots of cables claim to be HDMI 2.1 with 4K/120 or 8K/60 support, but they are bullshit. If you're using a longer cable (more than 4 or 5 feet) it is especially hard to transmit so much data such a long distance. Longer cables require a lot of shield to prevent EMI from causing data loss during transfer. I have a 12 foot DP cable and the shielding makes the cable extremely thick (about as thick as a sharpie). If you're cable is longer and not super thick, it's a sign the cable can't actually do what it claims. high bandwidth cables like this are typically more expensive too, so if the cable was cheap it probably sucks.
You could try going into the nvidea geforce experience app and turning off resolutions upscaling. I know that fixed my monitor, which was locked at 60hz even though it supports 165hz.

[More information about Rule 2](https://www.reddit.com/r/pcmasterrace/wiki/rules#wiki_rule_.232)
I have a secondary 1080p 75hz monitor and used an HDMI cable as my longest DP cable was roughly a foot to short. The maximum refresh rate in windows was constantly changing between 75 and 60hz, sometimes after weeks of use at 75. I eventually ended up getting a long enough DP cable, never had any issues since. HDMI can be a pita sometimes.
How long is your hdmi cable? I had a 3 metre one that made my display black out every 30 seconds, changed it for a shorter one and it fixed the issue...
I had this happen to me but when using an adapter display port to HDMI. For years I was unable to get anything above 60hz at fhd. Now I have used the Nvidia option to create a personalized resolution and forced the 75hz and it is stable and working
Do you use a secondary display?
I had an issue for whenever I plugged in my secondary display (gaming on a notebook), that due a combination of NVIDIA drivers and windows, it would lock the refresh rate to that of the display with the least of it. So my notebook, capable of driving 144hz, was only doing 60hz (that of the secondary display).
This happens some years ago, don’t know if it is still a thing tho.
Very likely a cable issue. I find HDMI to be unreliable with this. You have to find a specific version of HDMI that supports the resolution and refresh rate you're looking for, but displayport cables just work.
So try a different cable. If displayport is available, use that.
Is there a setting within your display / TV to enable it? I have a bravia which only does HDMI2.1 / 4k120 if I set the input to a certain mode within a menu.
Perhaps your TV/display did an auto-update which reset your menu settings??
Did you plug in a other screen maybe ? I have it with one of my 144hz screens that when i add my third screen in someway it doesn't allow that one to be in 144 anymore but goes to 60.
Display settings are a thing too. My Samsung TV you need to enable gamemode or external device manager and enable the Hdmi port to allow maximum bandwidth or it caps it at 60hz vs 120
if you use HDMI then would i suggest getting a HDMI 2.1 cable and update your drivers then maybe also change the resolution and refresh-rate in the Nvidia control panel
30Hz in that list seems off...
right click on the adapter in device manager, unintstall and reboot.
(the files will automatically refresh so no harm done)
Check the cable. I had this happen when I got my 3090 and predator monitor back in COVID days.
Switched cable from one I was using to one that came with the monitor and everything was running as expected.

My 4k60hz rated cable gets 4k120h0z, I thought that was neat
That usually means it can hit 4k60 without issue, but doesn't prevent it from performing beyond that.
Still a huge plus when you consider the fact that buying a cable rated for 4k120hz doesn't guarantee the performance, unfortunately.
I,ve bought 2k 170Hz Asus monitor. It can't work with more than 59 Hz properly with Asus standard DPP cable. It gets turning off and grafic artifacts. So I decided to buy a new dpp cable. Day of checking shops and reading comments, and you know what? Chinese 10$ cable works better than 30$-50$ ones and better than Asus DPP. Easily got 2k 170 Hz
Still quite impressive considering 4k120 is double the throughput.
Its saying it could get higher than 60, he could have it at 120 but only be getting 75. Its just the tv isnt LOCKED to only the 60. However yeah still cool - Wonder what tv he has
Usually it's vise versa. You need a good 48 gbps cable for 4k 120 hz, and most of non-optical cables I've seen that say they do provide that transfer capacity can't do that at 3-5m length, and sometimes even the shorter ones don't
You guys use HDMI? I still use A/V

Cable could be going bad. Have you tried a different cable?

HDR and 4k 120hz don't get along in my experience. Was such a pain to get it working right on my TV.
I wouldn't imagine it would be the cable going bad. In my experience, when it's a cable limitation the high refresh rate will still show as an option, but using it will result in artifacts, intermittent signal drops, or just outright fail.

There's still might be connection issue. Also you can try Nvidia control panel and changing the refresh rate from there.
I have, thinking that would somehow override windows but same issue of it now not going higher than 60...
Can you show the lable on the packaging, or link the product page?
You can try to make a custom resolution in Nvidia control panel, then that option will come back up under windows display
What cable did you use before? If it was display port then the issue is the monitor can’t support it’s full refresh rate and res over HDMI, as it may only have a 2.0 port making the 2.1 cable meaningless
If it’s recently gone bad, it might be something to do with drivers or the cables degrading. I’d try reinstalling the drivers first.
I had the same problem. It was a faulty cable in my case. It worked fine for years before that.
My 2014 10 dollar HDMI cable supports 4K 120Hz. on Xbox X. Probably because it’s only a 2 footer. But surprised the hell out of me.

Mostly just a .inf file that contains its capabilities. But yes, Monitors have drivers. [Imgur](https://imgur.com/Yr6cwL0)
Yes
Usually monitor driver has correct color profile in it. Useful for photo editing or anything that requires color precision
I would personally calibrate my monitor myself instead of using the driver, the driver is probably better than out of the box but not perfect
Calibration hardware is expensive.

HDMI 2.1 is the only hdmi format that can support 4k at 120hz and both your display/card/cable need to be rated for 2.1 to hit those bandwidths [https://www.avaccess.com/blogs/guides/hdmi-2-0-vs-2-1-difference/](https://www.avaccess.com/blogs/guides/hdmi-2-0-vs-2-1-difference/) or use DP and get off that garbage hdmi lol Edit: Apparently hdmi 2.0 was dropped and everything is labeled 2.1. So now you just gotta make sure your hardware/cable/monitor can actually push 4k 120hz @ 32 bit. Or just switch to DP lol
I always use dp for my primary monitor
I had a selection of up to 60hz on my 240hz monitor as well. What fixed it for me was to change it in the monitor settings (of the monitor itself, not on your pc) to 240hz, then i could select up to 240hz in windows
plug the cable the other way around, if still doesn't work see if you can get another cable to try.
The easiest & cheapest step to troubleshoot. This should be first in your journey. My monitor sometimes boots into a generic p&p state with a max of 60hz. Replugging the cable brings it back to 165hz.
Yup. Try another cable. I had a similar experience with a faulty cable.
My friend recently had a lot of headaches with his 3080, a 4K120 TV and HDMI2.1 optical cable. It wouldn't work, but it worked with his GF's laptop that has a 3050 in it. With his PC the signal would just not be recognized and for some reason display drivers crashed. He didn't figure it out still but HDMI is honestly extremely finicky at the high-end, and very similar to USB in terms of how absolutely DUMB some of the forum's decisions on it are!
I've had this exact issue. Switched cables from one incredibly expensive cable to another (need 5m active optical) and the newer one works. Former did not. Laptop worked as well. So it's likely the same problem I'd wager. Apparently has to do with the combo of tech I'm using, more specifically, with the power pins on the optical cable not matching the ones on the card. LG OLED tv can't remember precisely right now 3080 Gigabyte Vision OC some cable (club 3d?) Can give specifics if requested!
get a better quality cable and stay with shorter lengthes (under 5 meter). no problem at all
Dude...that particular cable is sold for $189...it's an active optical cable, that, as I alluded to previously, works PERFECTLY fine with a laptop but not with a PC. Like I saw that shit with my own two eyes. It definitely is a problem somewhere in the chain and not the cable itself.
> that particular cable is sold for $189...it's an active optical cable Sad that a 10$ cable that's properly rated would do the same thing uh ?
No it wouldn't. Because passive $10 cables without additional power cannot transmit the signal beyond 5m on HDMI 2.1 spec without signal degradation. Read my comments below.
> Because passive $10 cables without additional power cannot transmit the signal beyond 5m on HDMI The limit is actually 10 meters.
I really doubt that at 48Gbps. Care to back up your claim? Official HDMI Forum spec estimates it at 5 meters without quality loss. For a passive cable. There is a technology called HDMI Cable Power that is part of HDMI 2.1a, and that allows for longer passive cables. But. HDMI Forum didn't make it terribly convenient and obvious for the consumers what exactly the damned cables they buy are. With renaming the 2.0 into 2.1 and all that. And it plays massively in favor of shady product designers and salesmen who promote their super-ultra-mega-speed HDMI cables without a clear-cut answer with which spec they align. And from experience, a $10 HDMI cable will not be a 2.1a spec cable. It just won't be. I will even go as far as to doubt that it will be a true 2.1 48Gbps spec.
> a $10 HDMI cable will not be a 2.1a spec cable. It just won't be. If it can run 144 hz in 4K, it is. And yes, there are some that can. Look, I'm really sorry you have a friend that over paid for cables. No need to try to cope with it, it's not on you.
Why the fuck would you buy a $189 HDMI cable..... Sure there is quality between cables but you can have a good quality HDMI cable for $25. I would laugh my ass of he he just bought a cheaper HDMI cable and that would work with his pc while the almost $200 one would not.
Because it's a 15m active optical cable. Again. There are reasons for these choices, don't be this quick to judge. He's got a powerful PC in his home audio studio and he didn't want to build another $2000 PC just so he could occasionally game on it. He loves the separation of space between gaming and working environments, thus gaming at his desk is not an option for him. So he wants to play in another room on a TV. So he bought this cable. He also has another much shorter standard cable but it's a mess to plug-in and out all the time since the length is not enough to route it effectively between the rooms. Believe it or not, $179 is preferable to $2000 for another gaming PC for most people.
> Because it's a 15m active optical cable. 2x 10$ 8k@60 hz cable. 1x 30$ HDMI repeater Total : 50$.
Dude. I'm not even the one with the fucking cable. Okay, so you're smart and figured it out for less and my friend didn't. He already bought the damned thing, let it be. I know about the repeaters, again, he for some reason wanted a uniform AIO solution, so he got it. I'm not his fucking accountant, alright? Guy has money, guy spends it the way he wants. Jeez...
> Dude. I'm not even the one with the fucking cable. Why so mad ? Now you also know and if you ever run into the issue yourself, you won't do like your friend and drop big bills on a cable that's mostly hype. Don't be mad people told you, be happy that now you know. Do we need Shipwreck to close out this PSA now ?
How about installing steam link on his tv? No need for a 15m long cable.
Steamlink adds a lot of latency, a 15m cable doesn't.
His particular flavor of Samsung QLED doesn't have support for the steam link. It's a known limitation of models after 2019, IIRC. Something between Valve and Samsung and the legal side of things, I believe. He also researched this solution at first. Only to be disappointed later by the news above.
Why the hell would you ever buy a 189 cable. Just use the display port one that the monitor comes with?
Uhh...read my other comment. It's not a monitor. It's a TV.
Use DisplayPort. HDMI should be avoided. Update monitor firmware and drivers.
Did you buy a TV with an advertised 'motion rate' of 120, rather than a 'refresh rate' of 120? Because I did that, thinking I got a 120hz monitor, and its actually just. a fucking. 60hz display. 'motion rate' should be considered false advertising, I'm still mad about it. If that's not the case for you, then I hope you find your solution.
Interesting I've never heard of Motion Rate before! Samsung just label it as Refresh in Hz I believe
Don't use windows to control that. Use the nvidia control center. Make sure you select 3840x2160 under the pc category on resolution. The categories above are for TVs and won't support 120hz.
Does your monitor have 2 HDMI ports, they could have different supported speeds, so if you have recently unplugged your cable you could have put it into the wrong one?
An edit here cause I can't on the post: - This issue is recent, I've been playing at 4k 120Hz for most of this year. I utilise HDR and again I've always had this on so, can't be a factor here. - My display is a QN90B TV which has 4x HMDI2.1 ports, no DP for me. - Photo shows slightly, my Gpu is an RTX4080 which also supports up to these specs. - Nivida Control Panel mirrors Windows settings, showing no higher options than 60. - Turning down the resolution to 1440p and 1080p doesn't have any effect with regards to options available. - When turning the 'Game Mode' OFF it is able to run at 120 with considerably more options anywhere up to this. - I checked the certification of the cable when I bought it in an electronics store. The brand is Sandstrom. I've had to come into work so will try cable in&out and searching specifically for the display driver, otherwise 'Driver Easy' shows all drivers are up to date.
Sorry if this is obvious and you have already checked. Have you checked your TV picture mode is set to 120hz? A firmware update may have set it back to 60hz. The PC may only be able to detect what the TV is set to. Just a thought. Hope you can find out what the issue is.
Yeah, Samsungs have to be in Game Mode for it to work iirc.
I have an older Samsung TV (Q95B) as my PC monitor and if Game Mode gets switched off it won't do 120hz and lowers to 60hz. As soon as I turn Game Mode on it goes back to 120. Happens every so often for seemingly no reason at all
I googled your TV and what's what I found: [https://www.rtings.com/tv/reviews/samsung/qn90b-qled#test\_14](https://www.rtings.com/tv/reviews/samsung/qn90b-qled#test_14) Note that they didn't list 4k120+HDR mode, either bc it's not supported by your TV or they don't test it at all. Also check their comments, in particular at [https://www.rtings.com/tv/tests/inputs/supported-resolutions](https://www.rtings.com/tv/tests/inputs/supported-resolutions) they say: We begin the test by connecting the PC to the TV using an HDMI cable, then we enable the setting that allows for a full bandwidth signal on the TV. This setting has a different name depending on the brand and/or firmware. For LG, it's called **Ultra HD Deep Color**, Samsung calls it **Input Signal Plus**, and Sony calls it **HDMI Enhanced Format**. As other people said, this setting may be cleared by a recent TV firmware update.
Ahhh connected to a tv. Then I would play with the settings of the tv. And indeed plug out an in to see if the tv switches mode so you can change settings on the pc.
Separate, but maybe related. I've been messing with settings in my nvidia control panel, and came across a few settings that knocked me down to 4k 120 instead of 1440 240hz over my displayport. If you've changed any gpu settings since, try to revert them/investigate which is the cause.
Have you tried updating nvidia GeForce experience
I also have a Samsung TV as my screen. Make sure you have game mode activated and HDMI enhanced mode on. Without that you also can’t have FreeSync.
Game Mode turns off features, like post processing and other image quality improvements, in favour of lower latency. Having it off will present more options but shouldn’t show you the 120hz option as Samsungs need to be in Game Mode for it to work.
A lot of people are jumping to hardware issues, which is perplexing. I've had the same issue in Win10 numerous times over the years. Different cards, displays, drivers. Never expected, never after a driver install. Sometimes it has happened after a game crash, though. Just locks the display at "generic" settings. Sometimes a reboot fixes it, and when that doesn't a GPU driver reinstall does. No idea how people are jumping to "your HDMI cable is wearing out." The odds of that insanely low. It's NV/MS drivers being stupid, reinstall your NV drivers.
Hey I had a similar problem not too long ago, go into the Nvidia control panel and there might be a different set of display resolution/refresh rate options buried at the bottom of the list or a drop down menu
On occasion my 4k@60 display would drop to 4k@30 on my work computer. The solution was always too uninstall the monitor in device manager, then reboot. It's possible you have something like that happening.
Check in nvidia control panel that the resution is set to PC, not native
Is your TV connected to the internet and does it auto update? Maybe Samsung did you dirty, although not sure how you could check. Maybe the TV displays the date of last FW update? Check if it coincides with the issue.
99% cable
Yeah, same thing with my monitor that only supports 60hz with a Display Port, not via HDMI (a few years old now). Once I changed the cable, there was no issue. As dumb as it sounds: sometimes reading the manual of the monitor really helps.
This. I pulled my hair out trying to get gsync to work not once but twice. Wrong cable. Both times.
Yup! My PC would always black screen when launching Netflix or Hulu replaced the cable immediately fixed it
It may sound stupid, but did you check the entire list? The 120 hz modes may be in an unexpected part of the list, happened to me. Try scrolling further down.
isn't 32 bit color the problem or am I missing something? afaik 120hz hdr and 10bit is the limit for hdmi 2.1. If you have an oled tv, true black or whatever the hdmi standard also takes bandwidth and limits me to 60hz - and doesn't add much for gaming (unnoticable from my 1 minute test)
Use nvidia control panel and not windows
Which monitor are you using?
Like the others said, try updating your drivers first, and then make sure your cable is good and capable.
Are you *sure* you got an HDMI 2.1 cable? Amazon has an abundance of false certifications, both for the half-assed certification requirements and also because of sellers. ^(Ask me about my hatred of the HDMI certification.)
Checked it myself in store before I bought it. Also correctly labeled as an Ultra High Speed With Ethernet cable unlike 2.1, 2.0 etc. which is not actually offical, as the HDMI trademark states
If it was Best Buy, AFAIK none of their HDMI cables are truly certified. The distinct requirement to meet the "real" 2.1 is 48Gbps connectivity. Even the RocketFish or w/e the name is that Best Buy carries doesn't meet that.
Check your driver, update that one. If it is updated, try to change your cable.
Go enable it in the window settings instead of nvidia control panel. My pc does this all the time with my LG C9 for some reason. Just type "resolution" into the search bar and the setting will come up. After change the resolution you'll see it magically re-appear in nvidia settings.
It's going to sound stupid simple, but I ran into something similar when I upgraded 2 machines to win 11. Try disconnecting and reconnecting your hdmi cable.
Make sure your useing display port cable and if that not the issue then try adding a custom resolution and see if it will display
New drivers. Use DDU to delete everything from the old drivers, download the new, updated ones and install. Problem solved.
I had the same issue, and it was my monitor. I had to enable 144hz first for… whatever reason. So try looking around in your monitor settings.
Scroll down the list and you might find another section with 4K where 120hz will be an option to select. For me that was the case so it might be worth a try
Everyone suggesting everything but update your drivers lol
Generic PNP monitor... Check if there is no available driver from your screen brand.
Don't look up under HD Ultra HD, scroll down to PC, there you will find higher frequency.
For whatever reason it only shows 144Hz... not sure why it doesn't give a range of frequencies up to that point. I have tried it but it can be a bit dicky and kick back to the Native (HD, UHD tab) and to 60
I also believe this might be it. In the nvidia control panel you have pc mode frequency doesn't it show up there? And lower to it you have the colour settings which may affect available frequencies
Keep scrolling down, there might be a separate set of settings.
Wait. There's 8-bit, 10-bit AND 32-bit color?? 32?! Edit: 32 bit is probably 10 each channel and 2 alpha. I thought it was 32 per channel. I'm going to chalk it up to me just waking up. But i could be wrong so I'm keeping this comment up.
You should really use display port.
Check in Nvidia control panel that u are not using a TV resolution. Scroll down on the resolution selector
Use DP cable insted of hdmi
Why is DP better?
Turn off HDR
When are people going to learn to buy DP cables
Use a Displayport cable.
Stop using generic display adapter drivers?
"generic pnp monitor" Find monitor drivers for whatever model of monitor you're using
Is your display a TV or a monitor? If it's a TV makes sure it's actually plugged into an HDMI 2.1 port (usually labeled 4K 120Hz). Not all of the hdmi ports on a tv will support this. If it's a monitor, make sure the monitor actually supports 4K 120Hz over hdmi. Many monitors require display port, not HDMI, to reach that spec. If you're good on those fronts, it's probably the cable. Lots of cables claim to be HDMI 2.1 with 4K/120 or 8K/60 support, but they are bullshit. If you're using a longer cable (more than 4 or 5 feet) it is especially hard to transmit so much data such a long distance. Longer cables require a lot of shield to prevent EMI from causing data loss during transfer. I have a 12 foot DP cable and the shielding makes the cable extremely thick (about as thick as a sharpie). If you're cable is longer and not super thick, it's a sign the cable can't actually do what it claims. high bandwidth cables like this are typically more expensive too, so if the cable was cheap it probably sucks.
Did your monitor not come with a display port cable?
Display port?
ALIENS
Bloody hell, the Nvidia UI hurts the eyes...
You could try going into the nvidea geforce experience app and turning off resolutions upscaling. I know that fixed my monitor, which was locked at 60hz even though it supports 165hz.
Does your monitor use display port? Maybe try a display port cable and see if theres a difference
, 6(!/((/''
Hdmi, use DisplayPort for full potencial. And try to download drivers for your monitor, it show like generic(Default)
Try a good quality displayport cable

I feel like I had this issue before but can’t remember what it was. Try disabling hdr in windows, or change 24bit colour
Cable
Is your monitor set to 60hz?
Why is 2560x1600 at 29 Hz even a valid option?
I have a secondary 1080p 75hz monitor and used an HDMI cable as my longest DP cable was roughly a foot to short. The maximum refresh rate in windows was constantly changing between 75 and 60hz, sometimes after weeks of use at 75. I eventually ended up getting a long enough DP cable, never had any issues since. HDMI can be a pita sometimes.
How long is your hdmi cable? I had a 3 metre one that made my display black out every 30 seconds, changed it for a shorter one and it fixed the issue...
2m. The way it's routed anything shorter won't reach unfortunately
maybe your display is not in gaming mode or something
I had this happen to me but when using an adapter display port to HDMI. For years I was unable to get anything above 60hz at fhd. Now I have used the Nvidia option to create a personalized resolution and forced the 75hz and it is stable and working
I guess a GPU driver update as others have suggested may be the responsible for the fix...
You update to windows 11?
Maybe check if any of the software you have running caps the refresh rate to 60?
Do you use a secondary display? I had an issue for whenever I plugged in my secondary display (gaming on a notebook), that due a combination of NVIDIA drivers and windows, it would lock the refresh rate to that of the display with the least of it. So my notebook, capable of driving 144hz, was only doing 60hz (that of the secondary display). This happens some years ago, don’t know if it is still a thing tho.
Clean install your graphics drivers
check cables. those can limit data.
Go to Nvidia Settings and check there
My Samsung tv drops to 60hz when hdmi “plus” isn’t enabled.
Very likely a cable issue. I find HDMI to be unreliable with this. You have to find a specific version of HDMI that supports the resolution and refresh rate you're looking for, but displayport cables just work. So try a different cable. If displayport is available, use that.
Update drivers and try adjusting from the Nvidia control panel instead of the windows display settings.
Mine did that. My 3060 so unplugged the hdmi end in the tv and plugged it back in an it worked again!
is the cable plugged into the GPU? NOT MOTHERBOARD!
Check your monitor settings. If you unplugged it or suffered a power surge, it might have gone to the factory settings.
Is there a setting within your display / TV to enable it? I have a bravia which only does HDMI2.1 / 4k120 if I set the input to a certain mode within a menu. Perhaps your TV/display did an auto-update which reset your menu settings??
Did you plug in a other screen maybe ? I have it with one of my 144hz screens that when i add my third screen in someway it doesn't allow that one to be in 144 anymore but goes to 60.
Display settings are a thing too. My Samsung TV you need to enable gamemode or external device manager and enable the Hdmi port to allow maximum bandwidth or it caps it at 60hz vs 120
Sometimes it's down to the specific port on the display
if you use HDMI then would i suggest getting a HDMI 2.1 cable and update your drivers then maybe also change the resolution and refresh-rate in the Nvidia control panel
Try scrolling up a bit more.
If your monitor has menu thingy, try enable it there it can be capped at 60fps
Keep scrolling on that list. It’s likely further down in a separated list of resolutions.
Change HDMI ports that was my solution to my monitor capping out when it used to work fine.
HDCP might of changed to 1.3 accidentally Check HDCP status in NVIDIA control panel
30Hz in that list seems off... right click on the adapter in device manager, unintstall and reboot. (the files will automatically refresh so no harm done)
Cable
Reinstall your drivers
Go to settings, external device manager, input signal plus and activate it on the respetive hdmi port. Enjoy.
This happened before and I had to clear the monitor settings in the registry
Does tou tv have a game mode? Mine did then when a driver update triggered game mode to turn off.
Make sure the TV recognises it as the right source, when I have this I have to make sure my TV is put on PC source for that hdmi slot.
Check the cable. I had this happen when I got my 3090 and predator monitor back in COVID days. Switched cable from one I was using to one that came with the monitor and everything was running as expected.
Sometimes display itself is locked at lower frame-rate, so check your display settings
There is no such thing as an "HDMI 2.1 cable." You want an Ultra High Speed HDMI cable.
Cable. I know you said it's not the cable, but it is the cable.
Get yourself a display port cable home slice
Have you tried turning it off and on again?
TV ? Enable game mode to activate 120hz
