For some reason on my computer after I (successfully) changed the mobo and processor, whenever I put the resolution of my monitor (Native IS 1920x1080) It goes to one which is smaller(idk which, still says 1920x1080), about 2 cm of black boarder. I have already checked the ratio, which is 16:9 widescreen. It's also a problem as some games won't even start because of this. I can change it to a smaller one that will show 1920x1080, but like I said games glitch out. The monitor is an ASUS VW246H 24" Monitor.
