Hi There,
I just wanted to see if anyone has any clue about this particular issue (not so much an issue I guess but annoying nontheless). So I've aquired this nicely loaded G4 Cube (1.8 GHz G4, 1.5 GB RAM, 120 GB HD, stock ATI Rage 128), currently running OS X Tiger (10.4.11) and OS 9.2.2 (that one was fun setting up, let me tell ya). It's attached to a Samsung 24" LCD via VGA running at a resolution of 1920x1080 60Hz (native). All supported resolutions work great under OS X and OS 9, the only snag I'm running into is under OS 9 when I am running at the native resolution.
Whereas under OS X everything's peachy, when booting into OS 9, at some point my refresh rate appears to be modified presumably either by the OS or the monitor/video driver, which changes it to something not quite compatible. Even though the display remains at native resolution, the actual image appears to be slightly "compressed" or "skewed," meaning that it now has black borders on both the right and left hand side of the screen (which it shouldn't since it's the native resolution).
When checking the On Screen Display of the LCD panel, this is what I am presented with (not sure what the difference between PP and NN is, couldn't find anything):
Normal Native Settings:
67.5 KHz, 60 Hz PP
1920x1080
After OS 9 Changes it:
67.4 KHz, 60 Hz NN
1920x1080
What is strange, if I boot into OS 9 with all extensions disabled (shift pressed during boot) while the resolution is set to the good setting, everything's loading fine. If I boot with all extensions on or if they are disabled using the Extension Manager, the OS modifies the screen resolution and overrides the current setting. This is driving me nuts. Obviously the graphics card is able to handle this particular resolution but I have not found a way to keep OS 9 from updating it to whatever *it* wants. Makes no sense. I do not have an ADC->DVI adapter so I can't test whether it'll do it under the digital mode as well.
Do any of you guys have experienced anything like this before, and are any of you aware of any tips/tricks/tweaks/tools that could override the OS 9 settings? Sometimes I'm really not surprised why Apple killed off OS 9, it can be such a pain the the ... neck ... sometimes, I swear.
