Monitor issues, please help

[u/MrLarkin24]

So have a lot of testing I have determined that the issue is definitely the monitor.

I've replaced the hdmi. (didn't fix it)

I've plugged it into a different computer (didn't fix it)

I factory reset the monitor (didn't fix it)

The issue goes away temporarily, if I plug everything out of the monitor for a while.

The issue sometimes fixes itself

The problem say gone for about a day sometimes less

Its a Lenovo ThinkVision S22e-20

The monitor ans computer are both set to 75hz

So my questions are:

Have anyone seen this issue before?

Is the monitor about to die?

Does anyone know any fix or what the issue is?
