thats bizarre...could you take a screenshot of the monitors panel which says that?

my OS9 skills are rusty, but it would be my guess that for whatever reason the card is viewing both headers on the back of the card as having a monitor plugged in and it has them setup as a panoramic view. i would try and see if you could find a way to change the panoramic setting to a Mirrored setting, which should cause "both" monitors to revert to a single resolution and color depth. you could then try to setup the display you actually use as the "main" display and change the resolution and color accordingly.

just a thought.

i could check to see if i have any keyboard utilities, but no promises. i still owe a few other people stuff but i've been hella busy lately lol >_<
