Got myself a Viewsonic 22" and have a noob question I wanna ask:

My RTS games (War3 and Starcraft, both w/o native WS support) turns into widescreen whenever I use them; so I'm guessing that it's the job of Mr. 1:1 pixel mapping, no? Anyway, I wanted to ask if there's anyway I can turn it back to normal screen because I find it really hard to play them wide?

Thanks!
