L4D2 Resolution is not supported for me and I can't change it.

Hey,

I got my new PC at xmas, and I've had my 1366x726 (acer x193hq) monitor for a while before that. I've just installed L4D2, And the resolution it's running at isn't supported for my monitor. I can't go ingame to change it because I can't see anything because my monitor just says 'Input not supported'.

Is there any way I can change it without being ingame?

Steam\SteamApps\common\Left 4 Dead 2\left4dead2\cfg and look for video.cfg. You can change resolution there

Ty, I'll have a look at it now.
