Weird green pixels all over the monitor (not dead pixels)

[Ciciliati]

Hi there,

So today I was doing a play session as usual and all of a sudden I started seeing weird green pixels all over my monitor. At first I thought it was game related, but to my surprise, the desktop had the same issue.

I recorded a sample video to better illustrate what's going on (as screenshots apparently showed a perfectly normal screen):

This happens when the computer is at 60mhz frequency.

I tried lowering it to 50mhz and this is what I got:

Way better, but the weird pixels are still there. I'm sure the cables aren't faulty (tried 3 different HDMI cabes). Also plugged the computer on my Samsung TV and it works perfectly (even at 60mhz), which leads me to think my monitor is the problem.

It also seems weird to be that if I box something with my mouse, the screen goes back to normal (that can be seen on the videos).

I'm running a GTX 970 and my monitor is a generic Samsung 23".

Any thoughts on how I can solve this?

Thanks in advance!

It does indeed sound monitor-related from your description. But try running DDU from safe mode to clean out all Nvidia and AMD gfx drivers completely. The reboot and see if the issue is still present.
You can then install the latest driver again and see if the issue is gone.

Swapping out the gfx card with another one would be another test, of course.
