I have a problem with windows 8 resolution. It is set to 1920x1080 but it displays less! the image shows the actual size I get in firefox. (the height is the available one, full height-firefox menus). My problem is the width that is less then 1920 and the problem is not just with firefox, chrome and ie shows the same, everything on desktop is too big and even games don't show up as they should. Is there a way to fix this?
