Quake 4 resolution help...

[Dark Prodigy]

Messed around and changed my quake 4 resolution setting to higher than my monitor can support( I know it was dumb, just seeing how far I could push)...Now I get a black screen everytime I boot up Quake 4.
Any ideas on how to fix this or change my resolution back to where I had it without reinstalling the game?

open up q4config.cfg in the quake 4 folder.

search for "screenwidth" and "screenheight" and just change them to whatever u need..
