I'm running 10.4.11 on a mini G4 Bought ViewSonic VA2323WM 23" monitor. Looks great, except the VA2323 calls for 1920x1080 60 hz display and will only accept 800x600 and 1024x78 as alternatives. Everything else is "out of range".
Here are some more thoughts. This VA2323WM has two input ports, a VGA and a DVI-D. You'll get a slightly crisper display using the DVI-D port, but the VGA port also works, and these two will have DIFFERENT choices of resolution/refresh combinations. You may want to try a different cable and see if the other port gives you what you want.
The native 1920x1080 resolution is a 16x9 aspect ratio. Other combinations with the same ratio are 1600x900, 1366x768, 1280x720, and 1024x576. These are all uncommon combinations when the G4 Mini was current, so any of these may be a problem, and the 1920x1080 is definitely a problem unless you can live with the black stripes on the edges, which is what I do on my HDTV at the identical 1920x1080 on an identical G4 Mini w/10.4.11.
As I said, Leopard has DIFFERENT sets, and these are different for both the DVI port and the VGA port, so that means there are at least 4 different possibilities: Tiger/DVI, Tiger/VGA, Leopard/DVI, and Leopard/VGA. You might want to see what's offered in all four combinations. I'd zap the PRAM when changing between any of these just to get back to a default state on the monitor resolution that otherwise would be taken from the stored PRAM value (if available for the alternate System or video port).
One final option is using adapters and an old Mac video cable (the original Mac type with two rows of pins, different from either a VGA or DVI). For some reason, if you use an old Mac video cable with adapters on both ends, you get an even different set of resolution/ refresh combinations offered. I have no idea why this type of kludge using an antiquated cable with adapters can change the choices, but it does. This opens the possibility that other combinations of cables and adapters might change the offerings of resolution/refresh pairings.
