Re: ME3 - Monitors in-game have green pixels
Usually I am in favour of not changing a working system until there are problems, but you have a problem. 😉
Well, lets try something else first.
Did you reinstalled the game after you changed hardware?
Make a backup of your edited "Coalesced.bin" > Repair the game. (in Origin > Game Library > right click ME3 > Repair) > test.
If that don't works, make sure Origin is completely closed > move the "Config" folder from your "Documents\BioWare\Mass Effect 3\BIOGame" folder to your desktop > test the game
