I was using a 15 inch lflat screen monitor with my G4. Sold the G4 to my brother. . He has a 17 inch monitor. When he boots up, his desktop is tiny (as well as the menu bar). ANy one know what has to be adjusted? He said he adjusted things in the monitor Control panel (he is using 9.1). He said he changed the resolutions but is having no luck. Any one know what is wrong?
