Arc a770 Black screen and flickers of game when entering 3440x1440 175Hz 21:9, works fine at 120Hz.

This seems to only happen on overwatch 2, no other games have had this issue. My cable can handle the bandwitch of the data. During the flickering, sometimes my monitor shows that it cannot handle the resolution even though native resolution is 3440x1440 and max RR is 175.

It works fine until the aspect ratio is changed to 21:9 or the resolution is changed to 3440x1440 at 175Hz (just how OW2 res selection works).

I can still hear audio so it isn't a crash.

My Arc Control has been set to Retro Scaling - Off globally

Just seems to be luck of the draw, sometimes it doesn't even work at 120Hz at 21:9 or even at 16:9. Even with default settings sometimes the screen flickers into a black screen.

It seems the Retro Scaling reset, OW2 doesn't like scaling. Disabling fixed the issue
