I hope too, but it must be a real boost.

Read this article and you can see there are a brightness loss around 70 % between 2D and 3D (50 fL on 2D against 15 fL on 3D).

"With two 300W UHP lamps, this baby is brightTom measured nearly 50 foot-lamberts at 100 IRE with both lamps on! That's way too bright for 2D material, but the glasses reduce the amount of light reaching your eyes by about 70 percent, which results in a 3D peak-white level of about 15fLjust what a projected image in a dark theater should be and a lot brighter than any 3D flat panel and most commercial cinemas I've seen."

A better solution if you like SONY SXRD pannels, is the CF3D from LG.

Where can I post my order for a new JVC 3D projector? loL...
Can't await it... xD

so i guess there is little hope that mitsu will boost the lumens output till the final series.

Let me spell it out. Shutter glass technology eats up about 83% of the light available in 2D. That means for a 1000 lumens 2D projector, through the glasses you will get about 170 lumens. For a say 1200 lumens projector which is about the max a projector in the current packages of the JVCs would be about 1200 lumens giving one about 200 lumens. Improve the glasses abit and one will get a little more. Now I wil repeat there are things one could do for a 3D mode to incease the brightness. Overlaping the RGB,boosting the temperature of the white point. There are tricks and since JVC when they told me awhile ago about their models didn`t mention anything about using such tricks. So such tricks are not under any NDA with me. You better believe they are using one such if their brightness is significantly better than the competition. 3D colors are screwed up anyway if you calibrate in 2D. 3D calibration must be performed through the glasses with the glasses on and a spot meter type colorimeter or spectroradiometer must be used. Lets see the best buy ISFers do that.

The commercial standard is 2 to 4. What don`t we not get? People like bright, just as I prefer it in posters but I am more than willing to settle. Buy a Titan ultra 3D Reference, you can get all the 3D lumens you want. But you have to spend the BIG bucks. I don`t have them. The masses including me will just have to be satisfied getting the commercial 3D standard re brightness at home. Things can be goosed with color accuracy destroying tricks and the masses really don`t care about accurate colors. So some manafacturers will use the tricks and the masses will say wow.

Lets rough it and ay twice as many ft lamberts BUT if you want to double the perceived brightness you must quadruppple the ft l that means from 6 you would need 24. Its a squared function so doubling the foot lamberts would give a perceived brightness of about 40% more, not a hell of a lot That why the big projectors use two bulbs for 3D and only one bulb run less than full for 2D.

What motivated my remarks are that I really do like a bright pic, > 20 ftL, and Mark H's prognostications about the brightness (or lack thereof) suggested that this is simply not in the cards at present for a 3d pic. However, we may all be surprised next week.
