Alright well I just recently downloaded the Half Life 2 demo for PC and during gameplay it makes your screen widescreen or basically black sides on the left and right of your screen.And I'm wondering how I can fix this. I'm pretty sure there should be a tool in the control panel or somewhere but I don't know where to find it.So help is appreciated =).Thanks And this is in Genereal Chat not Off Topic so please try to be cereal.
