my lcd's resolution is 1920x1080 though so anything else will then have to use it's built in scaler to upscale it to that res anyway and that reduces image quality. the game itself can still run with the correct aspect ratio and have black bars on the side so it'll be 4:3.

that's how i understand it to be at least. i just got my first lcd monitor so i am still learning the differences between it and crts.
