HL2/Portal Shortcut Commands.

[BoomAM]

Hi.
Can anyone tell me the shortcut commands for HL2/Portal to set a specific resolution?

Ive been able to play Ep1 & Ep2 fine, but Portal wont run, it'll load the loading screen, then it'll minimise, maximise, minimise, maximise, minimise, maximise, etc; until it crashes.

Any ideas?

Thanks in advance all. .
