I recently purchased a ViewSonic PJD7820HD DLP projector. I got some 3D glasses that were recommended for it on Amazon initially and they work great but, due to my massive noggin, they weren't very comfortable. I found some "large" glasses that were supposed to be universal. Everything in the product description indicated they would work with any 3D DLP projector. But they won't synch up. The glasses are Xpand X104LX2 YOUniversal 3D glasses. I tried the autosynch mode and all of the manual synch options. No dice. Anybody know a way to fix this? Or can anyone tell me if they are simply not compatible so I can return them? Also, is there any surefire way to tell which glasses are compatible with which projectors/TV's before you buy them? I can't seem to find anything that explains this very well. Any help would be greatly appreciated. Thanks!

Viewsonic is not listed as one of the brands supported by those glasses on the manufacturer's website, so I would suggest you return them.

There are various types of glasses that will work with DLP Link technology; I used to own a couple of pairs of these, but got rid of them because they were too large for me and I found them quite heavy:

The Xpand X104LX2 are active shutter glasses and your projector requires DLPlink glasses. So the Xpands will not work. You will need DLPlink glasses that do 120hz also. Most of the new glasses do up to 144hz and should work. Sainsonics and UltraClears are okay. Some have better contrast than others. These specifically mention your projector: http://www.amazon.com/SainSonic-SSZ-...dp/B0085JBI6S/ You can make these slightly bigger at the hinges that fold the frame in. To do this, fold the frame in and carefully file some plastic away so when you unfold the frame the temples are wider...but make sure the glasses work well before you do this... (and I take no responsibility if you break anything...).

You can tell if you have dlplink if the screen in 3D mode, when looking without glasses, has a white or other color cast to it that makes the image have very weak contrast. That is caused by a sync flash that makes the glasses work and disappears when the glasses are put on. If you do not see this and just a double image with normal contrast, then you would have an active shutter 3D setup, which requires an infrared or RF signal that syncs the shutterglasses. Sometimes this is built into the projector, but usually requires an external dongle connected to the projector and you have to switch to active shutter mode.
