On a black background, half of the screen is gray

Hello. There was a problem with the monitor. On a black background, half of the screen is gray. There are no problems with other colors. What is the cause of the malfunction? This has never happened before.

after a couple of hours of using the monitor, this problem disappeared. Tell me, is this a critical problem or not?

The problem occurred 4 days ago, and lasted 2 days. There was a problem when it was turned on, but after a couple of hours of work it passed. There was no such problem yesterday and today. Updated the drivers.
There were no changes in the monitor.

Should I worry?

No need to worry about it. 

Please observe your monitor for some time and if the issue persists, please let me know.

Keep me posted.
