Help! I've recently got a Samsung S22B300 LED display, which worked fine for a few days, then for no apparent reason, the display area shrunk left and right by about 4cm, so now I've got black bars left and right. It's clearly the video system that's doing it, as drawing a square produces a rectangle, and text is squashed.
Resolution is set to native - 1920x1080, and I've fiddled around endlessly with the windows display settings and the NVidia control settings (under display properties-Advanced). Once I got it to go full-screen again (yay!), but then I rebooted, and it returned to black bars (boo!). Dunno exactly what I did, and now I can't get it back at all.
Anyone advise on what's going on and how to get it to display 1920x1080 properly?
