Windows 10: After monitor sleep awake, everything is frozen

Hello all,
recently I'm experiencing this problem in my Windows 10: When I wake up my PC from monitor screen (which is set for 3 minutes), everything is frozen - I type, it doesn't type, I move my mouse, nothing moves and then later after few seconds, minutes or too much clicking it goes back to normal and shows that what I was typing actually got typed. So basically it seems like computer screen freezes after monitor sleep wake up. I didn't have this problem before, it must be from recent updates probably. Anyone else having the same problem? This is my current build:

Edition Windows 10 ProVersion 20H2Installed on ‎2020-‎06-‎12OS build 19042.782Experience Windows Feature Experience Pack 120.2212.551.0

P.S. I was browsing Windows 10 feedback and I saw this very offensive post there. I know it doesn't have to do with my problem, but holy cow, how this is allowed there?

:)

 

Monitors won't go to sleep... Why?

I don't see how that is possible. If the computer is awake, a video signal will be sent to the monitors keeping them awake. Monitors go to sleep X minutes after no longer receiving a signal.

 

Windows 10 sleep

I'd already tried using default power settings - no change.

As you suggested I created a test user account, that also fails to awake from sleep..

Thanks for your advice, any suggestions for next steps?

 

Sleep problems awaking.

Installed the latest update Windows 10 on PC last week & Monitor doesn't wake from sleep. Monitor starts to wake but then appears 'DVI no signal' and monitor closes down. The PC sound as though it is waking. Maybe upon wake the PC is sending the vidio
signal to the wrong port???

Any suggestions??
