Question Monitor Flicker while Full Screened in a game


Aug 2, 2018
Hello everyone,

Made an account just to post here because I don't really know what else to do at this point.

I got a new monitor in May (Acer ED3 27" Widescreen) to replace my old PlayStation 3D Monitor (I know, what a piece of tech). I also have had a second monitor, the HP 2511x. After switching to this new monitor, I've noticed that every time I play a game full screened or windowed border-less (League of Legends, Apex, Modern Warfare) the screen keeps flickering. However, this flickering disappears while in windowed mode. I currently have a Vega 56 graphics card and the Acer is plugged in using a DP cable, while my HP is plugged in with a HDMI cable.

The annoying thing about this problem is this flickering isn't consistent across all games. I play a lot of Overwatch in Border-less Windowed/Full Screen with no noticeable flickering.

All my drivers are up to date, and I'm not sure what to do.

Thank you for your help in advance!
