I can't figure out how to prevent Starcraft from being stretched to 16:10. I have a Radeon card, so I tried going to desktop settings and enabling GPU scaling, but the option to Maintain aspect ratio is grayed out. Is there a hack to allow 4:3 aspect ratio with black bars?

Normally it is a screen setting.

What a concidence, I just bought Starcraft Anthology yesterday and was wondering the same thing.

Turn off pixel stretching on your monitor. Also, check the Tested mailbag, I think they go into it in more detail.

Change your scaling options under your video card drivers, both Nvidia and ATI have something that can compensate for this.  The monitor may also carry some form of scaling options.

its called windowed mode.  if it isnt an option in the game itself, then usually you can go into the config file and find something like "fullscreen=true" and set it to false.

I usually just hack the .ini config file to do that changing the values to my native rez.
