Until a good (and more affordable) 3D front projector becomes available, I've been considering a Mits DLP rear projector as an interim 3D solution, especially since the converter is only about $100. I do have some concerns, though.
I finally got around to seeing a Mits demo at an area Ultimate Electronics. It used the nVidia shutter glasses and a clip reel running off a Windows box - sky diving, Coraline, a host of other animation clips. I saw some problems. The first wasn't due to the technology, but instead was a result of poor TV placement. The Mits 65" DLP rear projector was facing the front entrance. The reflections washed out the image and negated much of the contrast, and therefore the depth of the display. I knew that was going to happen before I even sat down.
The more serious problem was ghosting. I could see both images on the screen at the same time - very faint, but definitely there. This is a deal breaker for me, no matter what the technology is. I'm assuming it was a result of a sync issue and hopefully not an issue of the LCD shutter glasses being unable to shut out all the light. If it's a sync issue, I'm assuming it was caused by an improper signal delay somewhere in the chain - that is, that one eye remained open for a fraction of the time it was supposed to be closed. Does anyone know if the nVidia system has an adjustable delay to fix such a problem?
The other possibility is that the shutter glasses let through part of the light even when closed. That would make shutter glasses (if it holds true for all of them) completely unacceptable for me. I'd be forced to consider a polarized solution, much as I'd rather not do that.
The other problem I noted with the display was a really weird sort of rainbowing. I'm not very susceptible to RBE, but I did notice it. It was odd, though, and unlike RBE I've seen in the past. This RBE was not clean, if that's a term one could apply to RBE. It looked like a "shattered" version of RBE, and was oddly more disturbing than typical RBE. I'm certain it had to do with the 3D "offset" of the images.
I took an opportunity to spend a little time with the Mits Laservue while I was there (not connected to the 3D source). I had read a report from CES in which the writer said the Mits Laservue was the most effective 3D he saw. (It was working with the Mits 3DC-1000 adapter and Blu-ray 3D, IIRC.) First of all, it has dropped to $4,000 from $7,000, so it was competitive with other Mits DLP rear projectors. There was zero RBE - due to the laser scanning system, I'm assuming. Based on what I saw, the contrast of 3D on this set has the potential of being outstanding, but I was concerned about the noisiness of the image. From a normal seating distance, the clips they had running on it all looked grainy. Up close, it was easy to see the diamond shapes of the pixels.
I came away from the demo and the Laservue thinking I'd have to see a much better demo or I would be very reluctant to buy into this technology, even as an interim solution.
