When I connect my new 12" PB to my old Apple monitor, the screen on the 2nd monitor won't stop rolling. I don't know exactly what model the old monitor is, but it's been around awhile. I was using it in college back in '98, and it hasn't been used for probably 3 or 4 years. My pointer will dissapear off the PB screen, but I can't see well enough on the 2nd screen to tell what's even on there. There's a small access panel on the back of the monitor that has adjustments for contrast, h/v position, etc. But I don't see any dials for vertical hold. Any thoughts on what the trouble could be?
