When running a dual monitor setup do you need the same resolution for it to work? Ive always had two 1080p 144hz monitors, but as im looking to upgrade to a 2080 or 2080ti im looking at also getting a 4k or 1440p monitor at least. Would i be able to keep one of my 1080ps for multiplayers to get 200+ fps. Or would i need to upgrade both to 1440P?
