My Macbook Pro 17 (2.4 GHz Core 2 Duo, 4 Gigs RAM) couldn't get usable color from the DELL LCD projectors at PMA Toronto this weekend.
The resident techie tried changing projectors, and VGA cables, all with the same unusable result.
I was using the Apple DVI to VGA adapter to connect to the VGA cable; and dual monitor setting, not mirrored displays.
I tried running the presentation using PowePoint MAC, Keynote, and even PowerPoint/Windows XP running under VMWare Fusion, all with the same poor unusable color.
Switching to a PC laptop running Win XP ran the presentation with acceptable color.
The techie decided the problem was either my Macbook, or the DVI/RGB adapter.
However, back at home later, my Macbook worked great with my Epson LCD, using either a DVI or VGA cable.
This same configuration also worked previously at the PROMASTER convention Palm Springs in July; with Epson projectors.
Comments or suggestions? Is there a compatablity problem between Macs and DEL projectors.
