I am using Windows 10 Pro version 10.0.17763

Thanks for giving me some info about gsync, but unfortunately you have completely missed the point of my post. I was not asking about gsync, I was asking whether there was a reason for my monitor to sometimes flicker to a black screen until I change the input in the OSD.

I recently bought an Asus ROG Swift PG258Q 240Hz monitor, and it has been working fine, until today. Today there has been a couple occasions where the screen would start flicking between showing an image and a black screen, at the same time it the power light would flash orange. In addition to this, I have noticed that when I go into the monitor's OSD settings it would show '1920x1080p @240Hz' in Windows, but when I go into Overwatch it shows '1920x1080 @144Hz' is this a problem, or is this because I have G-Sync on but the game doesn't always run @240fps? Any help would be appreciated. Edit: I have resolved the issue in Overwatch, for some reason the game reset the resolution to 1920x1080 (*144Hz) guess I need to set that file to read-only.
