Suddenly showing vertical lines and flickering
It just happened suddenly while I was using it, now it’s unusable. There were a lot of flickering and pink/black/white lines appearing. The monitor was also 1 year old and I’m afraid it maybe out of warranty.
The only change that I made with my monitor was that I replaced the power adapter since the first one broke, it wasn’t exactly the same brand and model, but I made sure that it has the same 2.1A output. It worked for a few weeks, and then the monitor broke.
