I'm experiencing a frustrating issue where one of my monitors goes completely static every 10-15 times my computer wakes up. It flashes on and off intermittently and emits a static noise from the built-in speakers. I've already swapped out the HDMI cables, so I don't think that's the problem. This typically happens with my main monitor, but occasionally affects the other one too.
This static issue arises when I click the mouse to wake the computer after sleep, but it can also occur while I'm actively using the computer. A couple of times, the computer has woken up by itself in the middle of the night and the static occurred then as well. The only temporary fixes I've found are either clicking the sleep button and then waking the computer up or unplugging and replugging the HDMI cord. I'm using Windows 11 on a 5070Ti with two Acer Nitro XV272U monitors. Any advice to resolve this would be greatly appreciated!

Have you tried using DDU to clean out your graphics card drivers? Sometimes leftover driver files can cause weird issues like this one. After that, install the latest drivers from the manufacturer's site.
Just a heads up, if you’re reinstalling the drivers, make sure to do it manually to avoid conflicts. Also, check if your second monitor starts working again after that.

I just did that, but the issue still pops up occasionally. Hopefully, it’ll improve things a little!
