Not sure the difference between these?? The main reason is because i need to reinstall OS9 to an IMacG3 i have recently aquired. I have the flat panel that came with my G4 Quicksilver (mirrored drive doors) but not sure which the plug is. Im thinking its a DVI and if so i can get the DVI to VGA adapter from apple and hook up the external that way so i can use it to reinstall and upgrade the firmware so to update to OSX but not sure which is the best route to go concerning the monitors. Any help?
