One interesting thing of note, you can align the projector panels for 2D, but when you put on 3D content, the Pixel Alignment feature does not work, or rather, the alignment is turned off.
This engineering sample has a lot more mis-alignment than I would expect on any decent production projector, so when I switch to 3D, it becomes easily noticeable when you are looking for it. The two images here show 2D, and 3D. 2D is post alignment and looks darn good. That menu in 3D is a mess, with red looking to be off by more than 1 pixel vertically. I repeat, I don't believe Epson would consider anywhere near this much alignment to be acceptable in a production unit.
And yet the picture looks great in 3D as well. I therefore expect final production LS10000 projectors to appear even sharper than this one, by virtue of a cleaner alignment since it won't have to start with so much error. The improved sharpness will be subtle, of course, but considering the image this LS10000 is already capable of, I can't wait to see one at it's best.
As mentioned above, the projector does NOT have support for 3D source material in 4K. Also of note, is that when watching 3D with 24fps content, you can use CFI (smooth motion) and Super-Resolution (including 4K pixel shifting). When switching to 60fps 3D though you lose the ability to use both Super-Resolution, and CFI. Note that standard and advanced Sharpening, and Detail Enhancement features still work.
I have no idea why this Epson looks so clean on 3D, it's about as good as I think I've ever seen on a non-single chip DLP projector, and those have no crosstalk at all.
Epson offers their own light weight, rechargeable RF glasses for 3D (shown above), but there are plenty of 3rd party universal glasses that work with Epson projectors, I know, I've have a couple models of XPAND glasses and two pair of Samsung 3D glasses for group viewing with the LS10000.
Let's talk 3D processing from a different angle. That would be 480hz processing. By processing that fast, there are narrower slices of on and off possible than slower processing. Since crosstalk occurs when one eye is seeing (briefly) what was intended for the other eye, this helps. As Epson explains it, this means when one eye needs to be closed while the other side of the glasses are open, they can control the "how long" it's closed (or on) in shorter increments. They've been doing that for several years though, so, while that helps explain improved crosstalk, it doesn't explain why this Epson seems so much more crosstalk free than Epson UB's and others.
Gone are the three glasses settings that determine how long the glasses shutters stay open, that are found on other Epsons (Sony uses two "speeds"). On other Epsons, there's a High setting with a lot of crosstalk, Medium with a more modest amount, and Low, which is the cleanest, but the LS10000 is a lot cleaner than the Low on the Epson 5030UB. Perhaps they dropped the control, because its not needed, or because 3rd party glasses always ignored those choices.
That means you can buy extra 3D glasses from under $20 each! Invite the friends!
I'd guess that the LS10000 is cleaner than the 5030UB even in the UB's low (cleanest mode - Low, and the UB's are pretty darn good for non single chip DLPs). Brightness in 3D and
3D Brightness: Dynamic mode is sufficient to do a reasonable job on brightness at 124" diagonal. No one will accuse it of being too bright, but it's not bad. It's comfortably But I'm writing this section while toggling between Hubble 3D on my DVR, (I have it on disc too), and The Hobbit on Blu-ray 3D.
Now I've never considered my self very sensitive to crosstalk, but I really do find it virtually undetectable. I'm not sure what technology is responsible, but I am truly impressed. There's definitely a dramatic difference between this projector's 3D and the JVC's (RS49/4910/X500R we reviewed earlier this year. JVC had made some major improvements to their, but had previously been trailing the competition. I'm pretty certain that the last JVC here is not even close to the LS10000 when it comes to how clean the 3D is.
The Epson to me seems virtually as clean as a good single chip DLP. If you like 3D, you will love it on this projector. I'm viewing The Hobbit (actually the 2nd part - Desolation of Smaug), with CFI on Low and Super-Resolution on 4K-3. Awesome! A thought - perhaps Epson dumped the 3 settings because they don't need them with this design, or perhaps its both that and 3rd party 3D glasses couldn't understand those differences (ignored that setting).
This is the sharpest looking 3D I've seen since watching 3D (1080p material) on Sony's true 4K VW600ES. That's saying a lot. There are additional comments about 3D in the 3D section under Picture Quality, where I discuss color.
