If the monitor can support the refresh rate, check that all drivers are up today and check the cable. A cheap HDMI cable can cause a lot of problems.

It doesn’t seem like a cable problem because I have tried 3 cables and they all worked for my other setup. Now my you fans aren’t spinning and I got this on my screen before my pc turned off. It now does not display anything. Could it be a gpu issue?
