Monitor Flickering with Lines

Community General Discussion

Hi everyone! Ive been having an issue for the past couple months and it seems to be getting worse. when my computer comes out of sleep mode my main monitor has lines through it and is flickering. Sometimes just waiting a few fixes it but sometimes I have to reboot to fix it. I didnt think it was my graphics card because my second monitor is hooked up to same graphics card and has no issues. The monitor is only like a year to year and a half old so I didnt know if my monitor was going bad or what. The graphic card is a gtx 1660 ti and the monitor is an acer xz321q. I just thought maybe someone has had problems like this before or may know the cause. anyways, any help will be appreciated. thanks!!!

Unfortunately with tech theres so many different possibilities I can only really give suggestions.

  1. Roll back your Nvidia drivers, and see if that has any effect on it.

  2. Swap your monitors cables, and see if the issue persists on your main monitor, or if it happens to the other, if so replace the cable.

  3. Switch back to your internal GPU and see if you have the same issue.

  4. Does this occur with shutting down, or is it only from sleep? I honestly never put my pc in sleep since these kinds of weird things tend to happen.

  5. It probably isn’t the monitor, but plug a different device into it, like a playstation or something and see if you have the same issues.

I’m getting that problem, but I know the reason why my monitor is doing it. I pushed the overclock setting on it for a year at 165hz which started to strain the bottom right quadrant of the monitor, about 5-6 lines are now damaged. Pushed it back down to 144hz and it cleared up right away, at least for a while. Still does it once in a while, but not as severe as it was before and goes away after a few minutes.

These are good suggestions.
Another thing to consider is load on the GPU, a second monitor can overpower some cards and cause things to go funky. Try using just one and see if that clears it up.

If the lines are straight, with all pixels in the same line being the same color. I’d be suspect of the monitor. The whole goes away after it’s warmed up thing is indicative of a BGA chip starting to lift, or possibly the ribbon from the display panel itself becoming detached. You can test this with what Chaoticsaurs mentioned:

If it does not change, then you’ll know it’s the monitor.
