One of 3 monitors is dark after playing Mass Effect Legendary Edition

I have 3 Samsung 31.5 monitors 2560x1440 144mhz I use on my computer system. GPU is RTX 3070 ti.  When I play Mass Effect Legendary Edition and shut down the game the monitor I play it on is darker shade than the others and I have to reboot my system to return the monitor to its proper shade.

It is irritating. It is kind of like looking at the monitor though a pair of dark sunglasses. 

Any solution to this problem. I have never noticed it with Mass Effect Andromeda.

I play the games on my Windows 10 PC through the Origin Client.
