I have a 22" 1680x1050 LCD monitor hooked up to my B&W G3 that has been chugging along fine at that resolution for quite a while now. All of a sudden, after a fresh reboot (I don't keep it running 24/7) there are no options for 1680xanything in my Monitors control panel (or control strip). And the frequencies next to many of the available resolutions seem a lot higher than I remember (like 120 - 200Hz!). What is going on here? I didn't install anything and I didn't change any extensions around.

I tried the "all resolutions" trick (holding control while clicking on the Monitors control strip). Nada.

I booted from a CD that I put together a while back that has 9.2.2 + the ATI drivers that make this combo work. No dice. (worrisome)

I tried resetting the CUDA button and zapping the PRAM. No dice.

The monitor is not at fault. I attached it to my PowerBook G4 and it went straight to the 1680x1050 resolution.

I removed the Radeon 7000 card and reseated it. That didn't do anything. (It's in the second slot, BTW. I keep the original Rage 128 in the first slot.).

Now, after the CUDA/PRAM tricks, the scrolling and redraw on Finder windows is sloooow. [edit: fixed that, disabled an extension I shouldn't have.]

Thanks in advance for any ideas. This is my animation workhorse. If I have to go back to my 17" CRT I shall weep.
