Dual Screen flicker when Loading/Closing games

[GT47R_Damo]

Hey all, so i recently upgraded my 770 to a 1080ti and also bought a new monitor, so i wanted to run dual screens 1 to play games the other to watch videos and all the other things.

Problem im having is when i load/close games i get flickering black screen on both monitors,

monitors are
Asus ROG Swift PG258
Benq RL2455

main monitor is the Asus one, which i have set to 144hz + Gsync and the benq is set to 60, i thought setting them both to 60 would help but it hasnt. i have tried with no Gsync and still have the same issue.

any help would be great thanks.

Does it just flicker and come back on. Or what.

yeah it flickers a fair few times before loading up the game or desktop

I think that's normal mine does it all the time, but my game never messes up. If you want to watch like a video though on the second monitor just make the game windowed should be in video settings. Good Luck!
