Black Screen when Exiting full screen application

[PurpleCodes]

I have a 3 screen setup and on my center screen where I play the game. ( A 180hrtz monitor) I have to play in full-screen mode in order to have all of the frames. However, if i try and tab out of the game. (only in some games) All 3 of my screens go black. Then after a few seconds, they turn back on. This only happens in a game where it takes advantage of 180HRTZ ie PubG, CSGO, and R6S. I have one idea on why it is happening. In the Geforce Experience app it says i only have 1080P and 60HZ where I have 180HZ I am unaware of how to change this or update it. (My other two monitors are 60HZ so that may be why.

This is because of Windows. As your desktop uses different resolution/frame rate, every time you change between resolutions Windows will need to adjust to it. Same thing would happen if you'd game at 1440p but run desktop at 1080p. There's no fix, not any real fix at least. You can run always same settings for desktop and games. Or you can run in windowed mode. Those are options if you don't like seeing that black screen flash.
