Strange computer problem for IT professionals?

I have had the following problem since the day before yesterday. I opened the laptop and the screen flickered. Moving the screen or pressing lightly on the frame changed the picture or even made it appear clear again.

Now I assumed that the connection of the screen wobbles or that there's a cable break, or that the screen is simply defective.

Now comes the strange. When I press Ctrl + Alt + Delete the picture is clear. Always. Without any physical influence.

If I leave the menu and go back to the desktop, it continues to flicker.

I have already updated drivers.

But how can that be? Hope someone can help me.

Known problem. Solution (from Microsoft):
Screen flickering in Windows 10 is usually caused by a display driver problem or an incompatible app. To determine if a display driver or app is causing the problem, check for screen flickering in Task Manager. Based on this information, you will then need to update, reset, or uninstall the display driver, or update or uninstall the app.

Thanks in advance.

But how is it that the flickering changes when the screen moves? Seems to be a software problem.

There's no flickering in the Task Manager. I had already updated the drivers. What now?

If the problem occurred after installing updates or the like. On? Have you tried system restore yet?
