BenQ W1070 3D
3D looks very good. Before I get going on the BenQ's 3D I've got an interesting story (cautionary tale) before I go further. I've been having problems with one of my long cables of late, ordered in someone's "top of the line" cables (off of Amazon - I was in a real hurry), and when I put on John Carter in 3D last evening, all kinds of crosstalk and judder. Switched back to that truly (but 5 year old), top of the line cable - an Ultralink, and all that garbage went away. I confirmed that the problems also were there when I switched to an expensive JVC projector. BTW the issue was with Blu-ray 3D, side-by-side off of HDTV didn't seem to suffer.
If you think you are the type who will upgrade in a couple of years (maybe to a 4K projector when they become affordable), that's a killer reason for buying really good cables.
Back to the 3D performance. With a proper cable, crosstalk is a non-factor. I found watching 3D to be rather enjoyable and relatively bright. Color was pretty good (in 3D), I don't expect color as good as 2D, and we have never tried to calibrate 3D. The excellent brightness allowed me to put on some widescreen movies and fill my 124" diagonal. Not bad, watchably bright. At 100" diagonal there's plenty of lumens for 3D. After all, consider that 400 lumens is more than enough (with proper lack of ambient light) to watch a 100" screen. With over 1700 lumens calibrated, that's more than 4 times as much. 3D no longer costs 75% of brightness even if it does cost viewers a good bit more than half the brightness. Translated, this W1070 can do a great job in 3D on an average sized screen.
I was very pleased with HDTV 3D. Everything from a Penn State football game, and some little league baseball I recorded in 3D, to a National Parks tour of Arches, looked really good.
Color remained good even in 3D. Of course we never attempt to calibrate 3D, so I'm sure it could be improved. If we find a 3D calibration disc, at some point I'll have Mike calibrate some 3D modes on future projectors.
Overall, very good 3D, lots of brightness, and an almost total lack of rainbow effect (for me) make this W1070 the best lower cost DLP projector for 3D that I've played with.
In other words: I really like it!
