Title: Profiling and calibrating DLP Projector
Post by: boku on May 21, 2006, 08:21:52 am

I am not really sure what forum to stuff this under. I am going to be traveling on/off for the next week or so, so I may not get back right away to explain this question any better. I thought my dilemma (if there even is one) might be common to others facing this (resolved or not).

I just ordered a Dell 2400MP DLP projector (~3000 lumen). I will be using it with a notebook computer (Del Inspiron 1505E) to produce photographic critique/educational/training presentations for groups between 5-50 people. I also ordered a 92" diagonal portable screen with a 50 degree throw. Budget, but the prices on this stuff finally reached a level that it made sense for me to jump in the water.

I understand that the quality of this rig may not be state-of-the-art. I also realize that digital projection has been getting better, but is not yet truly mature. Nevertheless, I want to optimize color fidelity, brightness, and contrast to the extent possible.

What products and techniques should be used? I will probably be using this rig in various dimly lit (but not dark) rooms. Assuming I do need to profile and calibrate, must this be repeated at each venue or session, or is there a way of determining an average (close enough) profile to use.

Any and all help will be appreciated.

Gretag-Macbeth offers a package that can profile projectors. I forget the name, but search their site and I'm sure you can find it.

The GretagMacbeth Eye-One with the Beamer module works great. I never travel without it.

Hi,

Colorvision Spyder Pro 2 comes with an accessory so it can be used for calibrating monitors. I happen to own one, but I'm not really sure how well it works. I guess that you may need a real spectrometer to get it really right. The spyder pro is cheap, so it may be worth a try.
