I'm looking at the new Optoma HD66 to watch 3D on Blu Ray and Directv later on in the year. I've searched around and can't find stand alone shutter glasses that don't hook up to a computer. Do the glasses have to be hooked up to a computer just to watch 3D from either Blu Ray or Directv?

hey, well i wont keep you hopes too high on 3-D, just because next year or whenever there might be a change in specs. but that said i ordered my hd66 because i need a new projector.
anyways the way i sorta figured it out is the 3-D bluray players will be able to send the signal to the glasses, i think its panasonic that is releasing a bluray player and glasses and once the glasses hit mainstream the glasses will be smaller and better.
also these glasses are most likley to be active shutter glasses.
so i would personally wait for the players and movies to come out before buying the glasses

Yea well I know they'll need to be shutter glasses, but I'm having trouble finding ones with out a computer hookup.

well i would really hold off on looking for the glasses, just because sony, panasonic, and all of the other name brands will most likely have them maybe even released with their players as a package. plus with more big names in the 3-d business now glasses might become smaller and cheaper.

It will depend on how Directv and blu-ray players output the sync signal and if the active shutter glasses can use this signal.

Isn't that what makes the Optoma HD66 "3D Ready"... that it will output the IR sync signal for the glasses? Or is there more to it than that?

The Optoma HD66 does have a great big advantage in that it is able to accept video streams coded for 3D (at 120Hz - twice the usual rate) and project them at 120Hz onto the screen. Getting shutter glasses to sync with that is another matter, but luckily, a much simpler one. The Optoma relies on DLP Link for the glasses to work, and the glasses now cost about $150 each.

More on DLP Link here:
http://www.dlp.com/projector/dlp-inn.../dlp-link.aspx

Also, most likely any major manufacturer of shutter glasses will sell an adapter or box with an emitter letting their glasses work with blu-ray players and cable boxes and any 3D capable TV. But, the uncertainty and virtual lack of 3D content now inspires the advise to wait a little longer if you can.

Several places around, people are saying they are playing the game Avatar in 3D right now - on consoles, not just on PCs. You might look that up and see how the glasses are attached to the system.

As "trickmckaha" says, there will be adapters galore but from what I've read it's the output device doing the sync signal not the display.

Syncing with the display is a much better solution since many sources may sync in different ways - which is why DLP-link is probably the best solution available now ...... until you look at glasses selection. CrystalEyes 5's are $600, xpand x102's are $150 and have been out of stock for months... There's a chinese company that makes them but doesn't sell them, and bitcauldron expects to have a set released "soon". DLP-Link glasses selection stinks for now though.

This probobly has no value in this post but im going to post it anyway.

A few years back there was a program you could open and it would convert a few games that ran on a certin program engine to the red blue type 3D. At the time 3D wasnt really that big, the red and blue lense thing people pretty much had enough of and i couldnt find any of the glasses anywhere. I went to e-bay and i found a user that was selling some sony glasses but the images wernt really clear so i couldnt tell if they were the red/blue ones or not.

I went ahead and won the auction and when i got all 3 pair they were similar to the "real D" glasses they use now at AMC and places. So here is the part that im confused about. If i hold the glases up infront of my monitor the monitor turns black threw the glasses. So isnt the glasses already doing somthing? why do they need a sync? i thought they are already working at a 60hz rate or somthing? When i rotate them the image turns from a blue to a yellow color

The glases have to connect to the Display/TV in order to sync with the actual screen display since there will be some lag between the output of the signal from the PC caused by processing time in the Display/TV?
Here is some info about the Nvidia 3D PC based soution which is not the same as the Blu-Ray disk 3D solution.

I have these glasses for my Samsung 3D-Ready DLP, and while they are like the nvidia 3D Vision glasses, they're not identical.

Also, I talked to the folks at Xpand the other day, they'll have the X102's (DLP-Link) in stock mid-March.

To the OP, if the projector you ordered has a 3-pin VESA connector, the glasses linked above will work with it.

Currently testing 3D with Sammy DLP, shutter glasses, and HTPC

I don't see that:

http://marketing.optomausa.com/PDFs/...6_Brochure.pdf

Here is the manual - it doesn't really say anything about 3D other than a menu that allows you to Enable 3D and Invert 3D

The hd66 and pro350w do not include a 3-pin vesa connector, they rely on dlp-link exclusively (or sync with source, but syncing with the display is a better solution IMO).
