Hiya there!
I've recently been struggling more and more with this monitor issue as depicted in the picture. It happens whenever I turn the computer on, e.g. when the monitor has been inactive for a while. These lines only occur then, and slowly go away by themselves - unless i change the refresh rate of the monitor. To be frank, this has been an issue for probably over 2 years - but its never been "this bad" before.
Got no idea what has caused this, why it (seems) to be getting worse, or what this type of monitor issue is called.
This is a AOC 32" screen, dont have the exact model - but if it matters ill try to dig deep to find that.
Appreciate any tips or pointers to this.
Have you confirmed for sure that it's the monitor and not your system? Plug it into your TV or something else and make sure?
It sounds like your monitor is shitting the bed based off the photo and your description of the issues but I like to remove variables whenever possible.
I got this screen from my brother and he had the same issue when he used it.
Damn that's unfortunate. Sounds like the screen is dying or already was when you got it.
I've had good experience with that brand of monitors on the past personally. Shame yours is kicking the bucket.
