    My G4 MDD has a Radeon 9000. It has the Apple and DVI ports. I'm using an Acer G235H monitor. The max resolution that I can select is 1920X1080. However there are no other 16X9 resolutions to choose from. It goes from 1920X1080 all the way back to 1280X1024. I've tried both the Apple port and the DVI port.

    I'd like to get a 1600X900 resolution for example but the option isn't listed. surely I can get that resolution as it worked fine in OSX on this same machine. I installed the latest ATI updater but it didn't seem to help.

    How can I enable those other 16X9 resolutions?

    See if you can find a file for your monitor. I have an LG E2242 monitor that came with a disk for the monitor file. As long as graphics adapters have their correct drivers, this issue should not arise.

    If you cannot find a monitor file/driver that is compatible with older versions of OS X or 9, try backing everything valuable up and reinstalling the systems. They should automatically detect the monitor to set the resolution.

    Could you clarify if you cannot get the resolutions in either OS X and 9 or if it's just one system?

    It was working fine in OSX and Mavericks but not in OS9. There's definitely no driver/extension or anything for this monitor as it's a newer monitor.

    I reinstalled OS9 but I get the same thing. I've also gotten Windows XP and Windows 7 to show the other resolutions.

    SwitchRes / SwitchResX

    Have you tried custom resolutions with SwitchRes (Mac OS 9) or SwitchResX (Mac OS X)??
