I have an iMac DV SE 500Mhz and a NEC 19" monitor connected to it, in Mac OS 9 I can make the resolution bigger like 1280 x 1024 because the NEC supports it and I do this my using Switch Res but how can I do his in Mac OS X?
I believe there is a plist file inside of your System/Library/ somewhere that contains an option to enable all video resolutions. I believe I saw the article on http://www.macosxhints.com, floating about somewhere.
