PowerBook video issues

Having a wierd problem with a PowerBook G4/12" and a ViewSonic PJ350:

Suddenly can't get video over the projector (same equip has worked well in the past) - but the PowerBook thinks it's sending video that way, since it has moved the primary output over to that, so all that's on the built-in LCD, is blank desktop and a moving cursor. Removing the video adapter from the PowerBook causes it to switch back to the LCD, so it's not a hang/crash.

Not sure what the fix is yet, but found some great resources/info at SFSU AV:


Portable Mirroring Activation Chart.
PB G4 mirroring tips.
AV Tutorials and Hints.


and the best collection I've seen, of magic Mac key combos.
