So, a friend has this G4 I was going to help him with as the Ati Rage Pro 128 (Apple 630-3075) and/or OS9 doesn't seem to like any of 7 tested monitors. Full HD resolution is only active with VGA hookup, when using the DVI connector there's even less usable resolutions even if using the same monitor and despite what monitor is used. So the problem is that the screen isn't stretched to the full width of the monitor and gets annoying vertical patterns because of it when displayed graphics is pushed together. I have tried another graphics card from another Mac but that didn't help and there was the same difference in available resolutions. I'm thinking another supported graphics card with some extra memory as well perhaps might be a solution. As I know near to nothing about these nice machines I need a recommendation about what to get that fits the machine and works in OS9. Maybe someone even has one for sale? Thanks for reading!
