I recently owned a Panasonic VT20 plasma, and the 3D on it was pretty incredible. There were only two major problems. The first, was eye-fatigue. I noticed after about 25 minutes of use, my eyes would feel extremely tired. I could keep watching/playing, but there was definitely a lack of comfort if I did that. The thing is, I've seen 3D movies at the movie theater without really any eye-fatigue whatsoever. Avatar is nearly 3 hours right? I saw that and had no ill effects.
This makes me think that getting a non "active" solution is the way to go.
The second issue I had with the VT20, is that it was just too darned expensive for a 50 incher. I know it has amazing 2D picture quality, but I'm not that picky that I need to spend that much for a 50 incher. For a 65 incher? Sure, but not a 50 incher.
Anyways, I'm very interested in getting a polarized projector solution at some point. I have no ideal how it's all going to work, but I think a polarized setup will be more easier on the eyes in the long term. Trust me... When you guys start watching 2 hour movies with these active shutter glasses, then you'll understand that eye-fatigue can be a very REAL concern. I was watching full World Cup games, and those take about 2 hours and 20 minutes. I took the glasses off during half-time to rest my eyes for a bit.
I'm a bigtime gamer, and I tried to play Super Stardust and Motorstorm, etc, etc, for long gaming sessions, but man... those active shutterglasses got on my nerves after awhile. I'm thinking polarized is the way to go, and if I have to roll with 2 screens, then I'm going to have to roll with 2 screens. I'm thinking of trying to get a pull-down silverscreen, that I can pull down right in front of my current screen. My biggest concern is setting up, and maintaining a dual-screen setup. I can imagine it being a major PITA trying to keep things proper with 2 projectors. Is there anyway to do a passive setup with a single projector?
