Here is my experience with this projector:
Its is great in terms of resolution, brightness, and ability to control color. But it does have issues with uniformity of the brightness output, I did an RMA for the first one I had thinking it was a one-off problem, but even the replacement had nearly the same issue. Basically the image is brightest just left of the bottom center of the screen, and I am surprised that all the gurus on this board have not mentioned it at all. Finally, tt has taken me a while to get 3D working but the results are pretty good.
Here is what I had to do to get 3D working. Basically needed a system which is NVIDIA 3D vision compliant.
1. Upgraded to a GTX 470 card.
2. Had to install windows 7.
3. Used HMDI cable to connect projector to PC.
4. Bought active shutter DLP link glasses (Im cheap so I bought these: http://www.amazon.com/SainSonic-Rechargeable-Mitsubishi-ViewSonic-Projector/dp/B00BVUNZUU/ref=sr_1_2?ie=UTF8&qid=1389213947&sr=8-2&keywords=sainsonic). Although, I should mention that my eyes get strained after a short while, not sure if it is the glasses or the technology.
5. Had to get 3D content (I used some HSBS mkv files that I found).
6. Had to get a stereoscopic video player from http://www.3dtv.at
Im still figuring things out, but here is that I do to get 3 movies to play.
1. Enable 3D mode in nvidia control panel (1080p 24 Hz)
2. Switch projector to 3D mode.
3. Play SBS movie in stereocopic player, choose sbs.
4. Turn on glasses, enjoy.
It is interesting that the H6510BD projector is 3D vision compatible even though it is not listed as so on NVIDIA's website.
Also, it bothers me that I can play movies using VLC (or at least I have not yet figured it out).
