I think cypher, cooller, and even avek use black bars when they play widescreen.

Do you think they anti-alias at all? I know the monitors they tend to get in competitions are like 120 hz but that doesnt help with some of the jaggy lines when your resolution is like 800 x 600 and I understand anti-aliasing through graphics card settings can have negative effects, especially v-sync if you put that on with it.
