for some odd unknown reason, the monitor on my old powermac will only display 640x480 resolution. its always been able to display 1024x768 just fine, but just today, i started it up, and it just wont do anything other than 640x480. in the Monitors control panel, it doesnt even show the other options. and the tab only says "Reccomended". i cant get to the "View All" part. last night, i defragmented my hard disk, and i repaired it with Norton Disk Doctor. I'm running Mac OS 9.1... can anyone help me?
