Describe your issue:
I recently purchased a new monitor, the Acer BM320, and a new graphics card to output 4K as indicated above, but sometimes while I am viewing my desktop with nothing open or sometimes when I am watching a video on YouTube or even when I’m typing documents on Word, I would see a group of vertical lines appear for a brief second on 1/4 of the screen. This happens on either the left or right side of the screen and doesn’t happen often. I researched this problem and thought that it might be with the cable, so I went and purchase a certified DP cable and the problem still occurs. It even occurs over HDMI. I even returned and replaced the graphics card and it still happens.

I’m at a loss. Unfortunately, I can’t provide a picture because it only happens for a second and it is not reproduceable. This problem also happened with another monitor I purchased and returned because I thought it could be monitor related - an LG 32 inch 4K monitor.

Does anyone have any experience with this?

I found this article on reddit. It sounds similar to what I am experiencing.

I found this video this looks like what is happening to my monitor. It seems to be a widespread issue.

I was getting the exact same issue when alt-tabbing and running any kind of video. Unfortunately it was my Radeon GPU and not my monitor. Not sure if it was a hardware or a driver issue but I'm on Nvidia now without any issues.

Thats is interesting to hear. Someone on another forum mentioned some problems with amd and 4K and a similar problem to me.

I'm actually going to purchase an Nvidia card soon to see if that changes anything.

May I ask what monitor you are using that had this problem?
