hi guys, this is zombie10k from the US site. I'm the fellow that got this all sorted out with BenQ (the 1:1 mapping issue). It took almost 2 months, but I was determined to get this resolved since the W7000 is the only High Power 'friendly' 3D DLP out right now. I use it at near eye level for max gain on my 142" 2.8HP.
I definitely recommend getting the 1.03 firmware. I'm glad to see it made it's way around the world.
I just received the latest set of BenQ glasses, but finding that they don't block the red flash as well as the Optoma ZD201's. I am very sensitive to this, maybe due to the high brightness in 3D mode with the HP screen. The W7000 is around 1100 lumens in 3D mode x 2.8 = I can see the red flash easily through the glasses (if the glasses allow it to pass). For some reason, the ZD201's are perfect in this regard. I have some more testing to do, but for now still recommend the ZD201's for best performance with the W7000.
The True Depths are also a good choice, they perform well (minimal Red Flash leakage) and are quite cheap here in the US, not sure if they are avail in the UK. We only have 1 place in the US that imports the ZD201's, the price is around $105 US.
I've demo'd/setup/owned a number of the current models and none perform quite as well as the W7000 does in 3D. The W7000 does a fantastic job at displaying the 3D image with no perceivable crosstalk/ghosting.
