I tried searching for an answer on this but couldn't find anything definitive. I have recently started using my Cube with a 1920x1080 60hz monitor. It works great in OS X 10.4 and Classic, but if I try and boot OS 9 it says the resolution is unsupported. I have tried opening Monitor preferences in Classic, choosing 1920x1080 60hz, but again nothing when I boot in OS 9. I used to use a 1280x1024 monitor and could boot both OS's fine. Is what I'm trying to do possible?
Got a tip for us?

1080p OS 9.2 dual boot on a Cube?

I’d say that’s the problem. I’m honestly surprised it’s able to display 1080 at all. Every time I’ve hooked up a Rage 128 to a higher resolution display it caps out at 1280x1024.
It’s a terrible card for any G4 IMO anyways. If you can find a Radeon 7500 to stick in there that would be ideal.
Presumably via DVI? Actually 1600×1024 (for the 22" ACD and SGI 1600SW) should be the max. I was able to (barely) do 1920×1200 via VGA on a Rage 128 (Pismo).

Maybe it was 1600x1024. I don’t make a habit of doing it. Non native resolutions drive me insane. Whatever it was it looked like crap🤷🏼♂️
It may work to take the 'NDRV' from 10.4.x and make an OS 9 driver out of it.

Thanks for the replies so far. I agree the video card is not the best, but it runs OS X 10.4 just fine at 1080p. It also runs OS 9 fine at 1080p if I boot holding shift to disable extensions, see below. But I'm in a bit of a catch 22 as it won't display anything with extensions enabled, and when they are disabled you can't change the monitor settings! 😆
So what else can I try? Somebody on another forum mentioned moving monitor preferences to the desktop and then booting, but I couldn't find a preference called 'Monitors' in the preferences folder, and I expect I then won't be able to change the settings anyway.
