Just an update on my spec. I am now running 1 Samsung 2343BWX and 2 ENVISION P2271WHL. I thought the d-sub to displayport adapter I was using at 4320*900 wouldn't work at 5760*1080 but it worked without issue. Loving L4D2. Hey Rebelstar or anyone else for that matter running Portrait Mode, does CCC ask you which way you want to rotate your monitors when you set them up like that?
