Error - Couldn't switch to requested monitor resolution

Every time if I try to start game I get error "Couldn't switch to requested monitor resolution" and game does not start.
Tried different resolution and tried to start as windowed mode, but nothing helps.

This started after Automation Upgrade. Played also Automation Preview Update and everything was fine. But after the Automation Upgrade game doesn't start. There was also Windows 10 Fall Creators Update, might be this messed up something?
Also uninstalled game and reinstalled, but still same.


Steps to Reproduce
start game

Well found someone with the same error on another game and the solution there was to reinstall the drivers. https://us.battle.net/forums/en/hearthstone/topic/20759159663

 

So I think we can try doing things the hard way. Download this and use it to completely wipe the drivers from the system http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

After restarting go download a fresh copy of the drivers and install them and restart again.

Didn't work. Made cleaning with DDU and fresh install to drivers, but still nothing. Also made reinstall to game, but nothing.
I am not sure if it's related but I think GeForce Experience used to see ONI but doesn't anymore.

Now I did find a solution. Right click on OzygenNotIngluded.exe and then Properties and under Compatibility tab Disable full-screen optimisatsion has to be checked. And then game works like before.
