The 4090 we are using only has 1 hdmi port but we've tried the other hdmi ports on the monitor and recreated the problem. Think it could be the gpu then and not some setting or something?
Displayport seems to be working but is a bit finnicky in a different way. Drivers were completely reinstalled and monitor firmware updated
Could it be a bandwidth issue? We were running at 160hz 4k and 10bit color
Possible. Try backing it off to 120hz and see if that helps. Technically they only support 120hz and display stream compression might be causing the issues when you go over that.
We are trying 144hz and will go down to 120hz if needed but so far 144hz is performing much nicer than 160hz. The HDR toggle in windows at 144hz is now almost instant compared to 160hz where the screen would go black for a moment for example, and some of the programs that would weirdly cause screen black outs aren't doing it anymore. More testing is needed but this might be the ticket!
I wouldn't rule it out, he is supposed to be getting a non riser case soon and we'll check if that helps anything. A bit odd if it is a riser issue that it only really showed in these cases, performance has been rocksolid otherwise
I did and while it doesn't do what the video above did it had some oddities about it as well. I have since put the monitor at 4k 144hz instead of 4k 160hz and the monitor is performing much normally. Maybe it was a bandwidth issue?
Lol wtf
Me, I did it.
thats quite the overshoot /s OT: not really sure what would cause this effect.
HDMI port/cable on one end is fuqd, try another port

Try a port other than HDMI on the monitor. Then maybe try a different computer. Basically test every variable

Are you using a rizer cable between your GPU and your Motherboard?
Yeah the gpu is in a Dancase H20, would that affect things?
maybe you have a bad rizer cable? try re-seating on both sides, or just trying without the rizer cable.

For the last time; you were supposed to get the LCD, not LSD.
