What made you "pull the trigger"? I remember that you were sold on the W7000 for 3D, due to brightness.
Are the Sharp G20 glasses that much better, or was the bang for the buck and 3 year warranty?
Will you still use the JVC for 2D or are you going with the Z30K as a single projector solution?
definitely still using the JVC RS55 for my 2D blurays. The 2D PQ of the JVC is outstanding, but I'll likely use the Sharp for HDTV and ambient light viewing. @ 1000 lumens in 2D, it does a good job lighting up my big HP with the lights on in the room.
There's several reasons I decided to give it a shot.Contrast
- I watch a lot of 3D movies, many of them are non-animations. The contrast / black floor on the Sharp 30k is better than the W7000. I did several hours of direct A/B comparison last night and the Sharp black floor in 3D is closer to the Sony HW50 / Epson 5020 which is a good thing. I've had several 3D DLP's using either red or white flash signals to activate the DLP link glasses. At this point, I'm convinced the DLP signal is damaging the perceived contrast as seen through the glasses. This corresponds with a test I did a while back with my original Acer 5360 720p 3D DLP. I used the Nvidia 3D vision glasses (IR) vs. a DLP link set (Acer uses white flash) and the IR glasses looked noticeably better in regard to black floor.Brightness
- Since I recently blacked out my room, I found myself turning down the iris on my JVC even further. My eyes quickly become adjusted to the dark environment and found myself squinting from the brightness of the HP. I have my projectors mounted very close to eye level on my 2.8HP and getting near maximum gain. With the pitch black room and the bright HP, I can get away with less lumens in 3D. I can also mount the Sharp ~4 feet closer to the screen vs. the BQ which helps a bit.Glasses
- strange enough, this is the main contributor. I may have decided otherwise if I didn't obsess over the Sharp G20 glasses. I've had many different 3D projectors in my HT and countless pairs of glasses. IMO, these are the Achilles heel of 3D projectors. I found glasses that performed well, but weren't comfortably and vice-versa. The G20 glasses are the 'Goldilocks' glasses for me... just right. They are feather weight and have the largest lenses I've seen on a pair of 3D glasses. When I wear them, they practically disappear with weight / comfort and the ability to not see the frames in my peripheral vision goes a long way to enjoying a long 3D movie.overall 3D performance
- 3D DLP's have 2 unique qualities vs. LCOS/LCD/SXRD. The first is they simply cannot display any form of crosstalk /ghosting, regardless of how intense the parallax is. The second is flicker as seen through the 3D glasses. I am hyper-sensitive to flicker. The worst is the JVC models, they give me a headache within 30 minutes of viewing. Sony HW50 is better, but still quite noticeable to me. Epson 5020 is the closest I've seen to the 3D DLP's. With the hyper-fast refresh rate of the DLP panel + glasses, the W7000 and Sharp 30K are rock solid in this regard. The image looks as solid to me in 3D as it does in 2D which lends itself itself to headache free 3D viewing.Noise
- In high lamp 3D mode, the Sharp 30k is a good deal quieter than the W7000. This isn't really an issue for me, but it is nice when the projector is quiet. especially when it's mounted 2 feet from my seating position.RBE
- less RBE on the Sharp vs. the W7000.
going back to the topic of grey scale calibration, I can assure the 30K owners that adding + gain to RGB will result in NO change on this projector with it's current shipping firmware. If the red is low, green and blue gains must be pulled in the negative to compensate. Perhaps PR had a different firmware at the time of their review that allowed positive gains to take effect.
