Okay, not at a home, but at the Sony Style store in Pentagon City mall here in Virginia.
It was a demo disc (apparently) running on Blu-ray as far as I could tell and some shutter glasses.
Nobody was waiting to try it out as well, so I got to sit down and watch their canned clips of Cloudy With A Chance Of Meatballs in 3D, which I had also see in the theater with my son in 3D. Intermittently they had a Sony starfield logo pop up with a ton of 3D put in.
My impressions:
There were four things I can say that I really noticed that mattered...
1. The colors were amazing. None of the junk with old red/green glasses. This was the polarized full color effect we maintain in theaters, except with shutter glasses. The colors popped and allowed for the vibrance of that film to shine through with excellence. Since this has been one of the biggest issues with lousy 3D at home, it was great to see it overcome.
2. The depth was what it should be. With 3D kicked in, you got an immediate immersion into the 3D that the movie presented. It was very satisfying to see the effect properly recreated on a 55" (or so) LCD display.
3. The shutter glasses had noticable flicker. Period. I'm not sure if this would cause me headaches. I'm NOT sure if they were operating at 120hz, or if this mock up was only running at 60hz, but the flicker from the LCD glasses was definitely there. I put my finger over the IR sensor which maintained timing and saw the shutters go WAY out of sequence before turning off completely (clear). It was interesting to see how quickly and accurately they restored their proper timing, but it still had noticably flicker.
4. The image dimmed, quite clearly, by 50%. While LCDs are still going to be great with this technology, especially with after dark viewing, the front projectors are going to need to pump out a few more lumens to maintain 100"-110" screen sizes (typical) and keep their punch.
Overall, while I was very happy with what I saw, the flicker was my big concern and I am going to wait to buy in until the shutter speed increases enough to deal with it better. Obviously, if I was watching a 60hz demo, then we may get an immediate jump with the actual technology at 120hz. It may take 240hz to really work to eliminate it though. We'll see. But, it was very cool to see a nice display properly render 3D with some lightweigh glasses which took care of the necessary 3D effect.
