About a month ago, I started having problems using my PowerBook with our digital projector. After about 20 minutes, the image on the screen almost completely disappears except for a small, vertical, jagged strip in which some of the slide can still be seen. Usually escaping the presentation and restarting it clears the problem for awhile. Oddly enough, the jagged strip will only appear on my laptop screen when in mirror mode; if I am using dual display mode to see my notes on the laptop, the jagged strip only appears on the projector's screen, not my laptop.
I reinstalled Keynote 2.0, eliminated a monitor extension cable and replaced the projector and its cable to no avail. So far the problem has not occured with PowerPoint, but I don't use PowerPoint enought to be sure that would solve the problem.
What else could be the cause? The monitor cable adapter, the monitor port on my PowerBook, the video card, Keynote, Tiger? It's very frustrating and not a little embarrassing in front of all those Wintel folks.
Any help would be appreciated.
