So I have this new Widescreen monitor, and StarCraft is getting stretched out to fit the screen. I can't seem to find any way to disable scaling it up to fit the monitor. The ATI Catalyst Control suite doesn't offer shit either. Any ideas?

buy a new monitor

Did you check your monitor settings?

What was so complicated about this? It is widescreen. Everything works perfectly. Old programs like StarCraft have a fixed resolution of 640x480. I need to know how to tell the computer not to scale these programs to widescreen. Ie: I want black bars on the side of the screen.

Can you change the monitor's horizontal screen size? You'd have to change it every time you wanted to play SC, but it would work.

You could get a program that lets you run starcraft in a window, then just resize the window to the size you want...
Get one from: www.creepcolony.com or www.starcraftsector.com. I haven't been on sector for a while but I think it's down...

Sometime I may include something in SCMLoader to help with getting the resolution settings you want for SC.
