I had a 20" monitor that was 1920x1080. When playing DOTA2 it seems like the top of the screen was chopped off or i didn't have enough of a vertical view. So I went and bought a 27" w/ 1920x1080 and its the same thing just everything is bigger. How do I get it to be the same size as the 20" screen but more area for a bigger view? I'm assuming I need a higher resolution.
