The image is printed onto the monitor. What could be the reason?

Question

Iron

There is a relatively ancient LCD monitor (I did not find it on sale).
1920x1080 pixels.
It works, but if, for example, you leave the computer and do not scroll anything, then the image starts to be "imprinted" on the monitor in half a minute. That is, it hangs with a translucent overlay over the content if you continue to work with the PC.
What could be the problem? Is it solvable? Or is it a burn-in of the matrix and the monitor can be thrown away?

Answer 1

It's time to change. Half a minute shows a strong degradation of the matrix. (if this is a hardware problem, which is most likely)
There is software for temporary "treatment", but it will not help.
In theory, this is not a screen burn, but image persistence
If you turn off the monitor for 20 minutes, does the image disappear?
Open a contrast image (a black circle on a white background in the center) and leave for 10 minutes
Then move the image. Is the circle still in place? leave for another 10 minutes
Close the picture. Is the first round still in place? Did the second circle print side by side?

Answer 2

Is it Dell by any chance?
To make 99% that nothing is impossible is the problem of the matrix. Replacing the matrix can be at least 50%, or even all 80.
