Windows 10 Monitor won't go to sleep?

Question

Monitors

The essence of the problem is that some application or service does not allow the monitor to go to sleep. I even downloaded nircmd for testing and the monitor turns on immediately after going to sleep. After a clean install of the latest Windows 10 + GeForce driver, the problem is actual (yes, unfortunately, I did not check). If you switch to safe mode, then there is no problem.
Tried googling this issue and couldn't find a solution. I hope for your help)

Answer 1

Try removing Geforce Experience - spyware. It causes more problems than benefits.
It naturally collects a bunch of information not related to the video card (and even about software that is not "games" at all), supposedly "to improve user experience", yeah, we know their "experience" :).

Answer 2

Run the CMD command line with administrator rights and enter the command:
In the report that appears, you will see exactly which processes or drivers are preventing the computer from going to sleep.
UPD: Of course, the question is stupid, but are you sure that you have sleep mode enabled?
In the settings that open, go to the System category . Then, on the left side of the window that opens, find and click on Power and sleep . On the right side, in the second paragraph titled Sleep , there are two items On mains power, turn off after and On battery power, turn off after . In these items from the pop-up list instead of Neveryou need to select the time in minutes or hours.
