I have a G4 eMac with 256MB RAM wich I upgraded to 1GB.. I did an erase and install on it with OS 10.3 out of the box. It looks like all went well except that the display is right in the center on the screen instead of filling up the whole screen.There is about 2 inches of black screen all the way around the display. I went into system Prefs>display but all it gave me was a resolution of 640x480 and colors : millions. I am at a loss on what to do. Anyone who can offer assistance would be appreciated.
