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?
