does 1024x768 scale well on native 720p display devices(projector) especially ones with vga input? i want to be able to display normal 4:3 games at 1024x768 on my HD display, but to be quite frank, PC performance comes before video/HD. i dont really care about black bars on the sides of the image, and i know its not going to be absolutely perfect. i guess im asking does this type of setup usually soften the image significantly?
