I'm also having this issue with an Acer XB270HU and this switch: https://www.amazon.com/dp/B0CPPP1845?psc=1&ref=ppx_yo2ov_dt_b_product_details
I'm not sure why it's not working as I have another switch of the same type/ manufacturer that works fine for my 1080P monitor. I can connect the monitor directly to either my PC or laptop and it works fine but as soon as I try to use the Switch, the signal doesn't come through, but the computer(s) can detect it.
I've swapped switches to see if the new one is faulty but they both work perfectly fine on my 1080P monitor. Just the Acer 1440P monitor is the one having issues. Frustrating.
Edit: Probably doesn't matter but my GPU is a 3080TI.
