What could have happened to the monitor?

Question

Monitors

At lunch it still worked fine, but in the evening I turn it on, and it’s like this (this is the Windows 10 welcome screen, there is an autumn forest on it, and in the lower left corner there is a clock that can be seen as 18:48):

What could happen to him?
This is still at the stage of inclusion, on post-messages it is so, and even when the computer is turned off. Reset monitor settings.
ZYZH there was no one at home. turned off the monitor in the afternoon, left. I worked from a coworking space on a teamviewer.
I came in the evening, I turn it on - and it is like in milk, everything is covered with white. nothing was dropped, the cable was stuck / stuck and fidgeted - it does not affect in any way.
I describe what is in the picture (I don’t see it on the monitor, I did it on the phone and sent it from it, the effect was visible there) - as if the image is visible through a white background of 60-70 percent opacity. That is, everything is on the screen, I'm using it now, but the letters must be strongly guessed to read.
It's been 2 months. The monitor seems to have started working normally, so it was 2-3 days.
Now the same joke again - the monitor has become almost white, the image is barely visible through the white.
Every 20 seconds the image freezes for exactly 5 seconds.
So it was also 2-3 days, gradually the image appeared and the hangs disappeared.
What is being done with it?
ZYZH is LZH, there is no service center for it, but to give it away with a description in words that there was something, but now it is not there - I don’t want to. I would like to understand what exactly is dying. Maybe someone from the description will understand what it could be, and whether it lends itself to exorcism, so that forever.

Answer 1

Maybe they dropped it, maybe the cable came loose. It's not very clear what's wrong with him. Describe in more detail.
