MacBook Special Report: Projector issues
Like the MacBook Pro, the MacBook exhibits some oddities when connected to LCD projectors via DVI.

"I just got back from a business trip where I attempted to use my MacBook (2GHz, white) with two different projectors at two different customer sites. Both were VGA projectors with different resolutions and I connected using the mini-DVI connector. In both cases the MacBook accurately detected the projector model and display resolution. However, problems occurred when the screen saver kicked in. I was using Microsoft PowerPoint 2003 for a presentation to some customers. Any time I talked long enough for the screen saver to trigger, and touched the keyboard or mouse to bring the system out of screen saver mode, the external display became unreadably garbled. The only way to bring the display back was to quite PowerPoint, change the display resolution of the external display, and then change it back."

Video projectors have differring 'nature resolutions - ie 800x600 pixels'.
There is no point to go above this and the video output should be the same
from the computer if possible.
Yes, I did wind up changing the profile to disable the screensaver during
presentations, and I was using the natural resolution in both cases.
Nonetheless, I think it's fair to consider the inability to smoothly emerge from
the screensaver (when connected to a projector) a "bug."
Thanks, I've tried all available resolutions, including the one that matches the projector (1024x768). Screen saver was not running when any of these tests were performed. Not sure how "shut off the screen saver" in OSX. There is no "null" screen saver, nor an "off" option.

- I have a Olympus VP-1 that is great; tiny and powerful. Unfortunately no longer produced. (http://www.olympusamerica.com/cpg_section/cpg_archived_product_details.asp?id=1083) It worked perfectly with a MBPro G4 and with an MBPro Intel, but will not fire up with the Air. The projector has DVI input. It currently works with the other Macs. When I plug it in to the MBAir using the micro-DVI to DVI adaptor, the MBA screen blinks blue like it's about to recognize it, but "About this Mac" reports that no display is connected. The projector also reports no video signal. Unplug the projector and the MBAIr screen blinks blue again, like it knew it was there, but no dice. Detect Displays has no effect. Also tried another Micro-DVI to DVI adaptor, and both work flawlessly with a Cinema Display. Any ideas? The only thing I can figure is that the pinouts for micro-DVI are not the same as DVI. Any help would be appreciated. I'd solder an adaptor if needed.
