Can't change screen resolution back to 1366*768 on Windows 7 Ultimate
Hey guys,
I'm sorry to post yet another thread about this problem, but having gone through all the ones posted (and resolved) so far, I'm convinced my laptop has developed some other problem than the ones people have listed so far.
Basically, what happened is that my Lenovo Z580 laptop (15.6 inch screen) running Windows 7 Ultimate SP1, which usually runs at a screen resolution of 1366*768 suddenly switched to 1280*800 following a system restart. There is a vertical black bar on the right side of the screen, and there is no option to increase the screen resolution beyond 1280*800 (I am currently using 1280*768, but it's still terrible). I have updated my graphics driver several times now (Generic PnP Monitor, Intel HD 4000 Graphics), but to no avail. Anyone have any idea what might be wrong with my system? Would a system restore help (the problem started after I restarted my laptop following an iTunes update)?
Any help is much appreciated!
