Improve projector display on a MacBook Pro Laptop Macs
After switching from a G4 PowerBook to a new MacBook Pro (Tiger to Snow Leopard), I found that external projection displays were noticeably dimmer and off color.

I tried calibration with the ColorSync Utility (located in /Applications/Utilities) without success. I copied the VGA color profile over from the G4 (Version 2.0.0) and changed from the Snow Leopard color profile (Version 2.1.0) and the result was a major improvement in the projector image.

[crarko adds: I haven't tested this one. It's good to know the color profiles are compatible. If it's a projector you use frequently, creating a custom profile for it in ColorSync could also be useful.]

I have problems with my projector too, but i never had Tiger. Is it possible to have your vga configuration file? Thank you

The color profile that worked well with the two projectors I use (Sanyo & Epson) is VGA Display-5B81C5C1.icc. This is very small file (4K). I realize that the gamma has been shifted in Snow Leopard but I was moving the gamma as low as allowed in calibration still did not get adequate brightness. I am sure what the best way for you to get a copy of this color profile - the Preferred CMM: Apple, Specification Version: 2.0.0

As such Apple changed from a Gamma of 1.8 to 2.2 which is what most of world uses !

I also concur that setting up projector with a good colorsync profile will produce better results as well.

Could it be related to Apple changing the default Gamma from 1.8 to 2.2 in Snow Leopard which would result in darker images on screen?

Just go through the non-recommended profiles (deselect "only profiles for this screen") until you find one that looks OK. In my case, the profile for my projector (correct make and type and all) produced a horribly dark picture, but one of the other ones (I think it was Apple RGB, not sure) looked absolutely perfect. Bizarre...

I've had this problem too. Doing what you describe also worked for me. I was using Leopard at the time.

You should use the calibration tool from the 'displays' pref pane. That will let you tune things more precisely, and save a custom profile for just that projector.

Actually this was my first approach. The projector screen was so dark that calibration images were not useful. Decreasing gamma as far as possible still did not produce an acceptable projector image. The change between the two VGA color profiles was dramatic. I, too, tried all the color profiles available in Snow Leopard. None gave anything close to the old VGA color profile.
