I want to buy a $180 22" TN monitor with native resolution of 1920x1080, aspect ratio of 16:9. My budget is good enough for a ATI 5770 GPU strictly. I want to know if i play games at 1280x1024 or 1680x1050 to gain some frames will it be ok? Will the image quality be sacrificed? Will i see black bars on top and bottom? I am only allowed to play games at native resolution?
