Just used my BenQ for 3D for the first time this weekend. I was using a set of the Sainsonic 3D glasses.
Similar to these, but I can't find the exact model I got. They were a Christmas gift and I'm finally getting around to trying them for the first time...
I was very happy with the results. Easily as good, if not better than what I get at the movie theaters. This was something I wasn't sure about at all.
The DLP Link is a interesting technology. The screen turns completely red when using DLP Link which surprised me. The glasses did a good, but not perfect, job of blocking the red out. I wish that the red wasn't quite so intense in the image, but it is what it is I suppose, but BenQ could certainly benefit from making available an aftermarket RF system for their projectors (all of them).
Still, the 3D was good. I watched Prometheus. It did not have extraordinary pop-out, but it was decent. It was pretty much what I was expecting. I may go watch Avatar and see how that looks.
BenQ immediately recognized the 3D disc and started playback. I didn't touch the projector, BD player, or anything else. I just stuck the disc in and it started to work.
The glasses were easy to use. One touch turned them on and they synced right up.
The glasses 'power' button also reversed the sync. This wasn't necessary, but worked flawlessly. After they were on, one touch and they switched sync. One touch again and they switched back. Press and hold for a few seconds and they powered off. Worked perfectly!
The pop-off effect was decent. I'm not sure if the Panasonic allows me to adjust for screen size, but I will check in their setup/menu system to see if I need to adjust from my 64" screen to the 161" screen I was using.
Brightness was reasonable considering my screen size. It was a bit dark, but acceptable. I will know better after I see a few more movies.
Minuses: Probably my biggest issue was that the glasses allowed some red through from the DLP Link sync signal. From what I understand, this is a glasses issue, so I may pick up another couple of pairs from a different manufacturer and see how they perform.
Overall: I was excited by the entire process. It was great to see just how easily it worked and how good it looked. I have crosstalk issues every time I go to a movie theater, so IMO, this had less cross talk and provided as good, or better of an overall experience.
My player: Panasonic BD220.
HDMI: Monoprice HDBaseT - 50 feet to the receiver. Then 40' over HDMI to the projector.
Audio - Just using stereo audio at the moment for this as it was just a test.
Screen size: 161" screen - 1.3 gain
Used the BenQ default 3D settings. Adjusted brightness partway though, then adjusted back down as it raised the black levels to much.
I didn't check to see if the projector kicked up to high brightness mode or not, I may check that with my next viewing.
At some point I need to try 3D through my computer, but I have not done this yet to see how/if it works well.
