How do you make PS3 more brighter?

[T3kNi9e]

I got CoD4 on PS3 and 360 but the PS3 version is alot darker. Maybe its because its hooked up to a standard TV and 360 is hooked up to a plasma monitor, but is their anyway to make ps3 brighter?

go in your t.v. settings or your display setting maybe. but i find HDTVs are actually darker and harder to play on (on default settings) than regular tvs.
