I have a PowerMac G5 @ 2.5GHz (PowerMac7,3) running MorphOS 3.14, with a Radeon9600XT 128MB graphics card @ 1920x1080 thru DVI without issues. Since I got a new monitor that takes 2560x1440, I wanted to use that mode, and while it shows on the monitor mode list, it is not available to select on the Screens preference. If I edit the mode and press "Test", MorphOS freezes (or looks like it - the image freezes and the mouse cursor disappears). I've been trying to find out if this Radeon 9600XT 128MB (Mac version) supports dual-link DVI, but without much success. Any help/pointers will be appreciated.
