HaloMods "Classic" Read-only Archive

my screen can only run on 1024 x 768 or 640 x 480 and ive fixed this before by switching to the old computer screen and changing the resolution on halo and then switching back to my tv screen but is there an easier way to do this cuz im really lazy
ive tried going to properties and changing it there but it doesnt work so...

I don't really understand what you mean. But a TV (non HDTV) only has a resolution of 648 x 486, so your not going to have better resolution on a TV. To change the resolution on a PC screen in Windows you can just right click the desktop, go to properties, click the settings tab and change the resolution.
