Hi Greg, Well I am trying to get feed-back from colleagues with hands-on experience with 3D DLP as a support for teaching and/or small-group seminars. Please, could anyone answer my (practical) question regarding which beamer has worked best, in their hands, for a 30-50 people conference room. Later on, after I've got an answer on that, then I will perhaps address a new question regarding glasses. Many thanks in advance. Nadir PS: Thanks Greg. May I say the actual spelling is "Bonne chance" as luck is a "feminine" word in French (with all due implications). Pr. Nadir T.

Hi Nadir,
Definitely investigate the ViewSonic products, but from their website, it is unclear what 3D-ready means to ViewSonic. You'll need to talk to a salesman. My guess is that they only work with the NVIDIA 3D Vision active glasses and if so, for a large audience, you'd would need the more expensive NVIDIA 3D Vision PRO glasses (they use RF instead of IR) for people in the back to reliably see the stereo images (alternatively, you would need several IR stereo emitters to fill the whole room -- just like a movie theater, don't get stuck behind the big guy).
Presumably you have a conference room that you would like to put the projector in. I'd recommend having DepthQ bring a demonstration system to that room and show you stereo images (eg., a 3D movie) and where they think the farthest reasonable sitting position is. Then you can stand at the back and the sides of the room to see for yourself.
Bon Chance,
Greg

Hi Matt,
Thanks for your input.
First, I should correct my ealier statement: DepthQ sells Christie's products but does not manufacture them.
From your mail, I understand that 30 people is the largest audience you can pack using the 3D with DepthQ, otherwise correct me please. Active stereo glasses 'Xpand' cost around $100, now, but battery replacement can indeed become costly over time.
What sort of tricks have you been able to collect over your 15+ years experience to implement stereo correctly.
I hear elsewhere that the ViewSonic DLP beamer (~$1400) might be a better option and that it is worthless spending more money.
GREG- I also need your input.
Best,
Nadir
