I don't have the 3d Xl but I recently purchased the monoprice 3D Creator ($100.00) from monoprice.com and a pair of Optoma ZD101 DLP link shutter glasses from Amazon.com. This little box is amazing. It turns bluray 1080P 2D movies into crystal clear, full colour 3D from my Optoma HD 66 projector with a 120 inch screen. I also have an HD70 and picked up an HD66 recently on sale as I wanted a brighter picture and was interested in 3D. The 3D movie quality actually seems to be better than the 2D quality but a little darker. It also works great on 2d DVD movies from my Oppo DVD player and on digital HD 720P TV too. Absolutley no ghosting and perfect sync.
I am watching many of my 2D bluray movies over again in 3D, many seem like totally different movies, King Kong by Peter Jackson is amazing, Independence Day, the new bluray versions of the Jurrasic Park trilogy, Sanctum, The Hunt for Red October, Transformers 3, Avatar, I-Robot, are all amazing in 2d to 3D bluray by the Monoprice 3D Creator. The other interesting thing is that while I sometimes see rainbows with my Optoma HD66, when running in 3D I never see them, even if I try.
Anybody with a 3D DLP projector and espescially the Optoma HD 66 should do themselves a big favour and get 1080P 3D ( better picture than 720P native on HD66) for $100.00 + glasses, you won't be disappointed. If you just use the Optoma 3D XL you will need to also purchase a 3D bluray player and will be limited to watching the limited selection of 3D blueray movies available. With the monoprice 3D creator you turn your total 2D blueray and DVD collection into 3D + watch sports in 3D HD. It migh sound like I am almost posting a commercial for this monoprice unit but I rarely have gotten so much enjoyment out of an electronics purchase for just $100.00 - could have easily been 5 to 10X the cost.
