Hello, I have a Dell Monitor - Gaming Curved 34" S3422DWG.

I usually have 2 laptops plugged in, I frequently jump from projecting one to the other.

Yestarday it started failing, showing a gray light, it was on, it just showed solid bright gray color. After fiddling the little menu knob for a while, it finally showed my desktop again. Then later I tried switching to the other laptop and the same happened, but this time, it never showed anything else again.

As a last test, I plugged it into a different PC, getting the same outcome. So it's not the computers, it's actually the monitor.

Anyone knows this to be a known issue? Which other tests could I do? I'm willing to open it, my guarantee has expired, so I'm ok with the risks. Any knowledge or suggestions are welcome.
