So I've been using my Olevia 37" 720p HD LCD as an extended monitor for my MBP for months. It has always worked fine, set at a native widescreen res. (I think it might have been 13something X 768, not actually 720). Today I plugged the monitor in like I always do and all the settings were gone. it was set to mirror the MBP display, and now all the resolutions are wrong. I can't find one that looks native, it has black bars on the sides. what happened, and what should I do?
