Prebitchin is better than bitchin after delivery. Actually prebitchin is very therapeutic. You don't have to experience anything. Nor do you require any expertise. A completely free bitch.

I am feeling fine and I will wait from the actual production models to hit and be measured before I load, unlock, and fire.

Do I read several defensive against the prebitchen posts?

Is this such a post?.

You of course can bitch all you want about this post. Its delivered when I press the submit button.
Bitch, bitch, bitch.

I would still maintain any preorder because it commits to nothing and actual measurements of production models should be out there from those purchased from a West Coast dealer before the product is ready to be shipped by your East Coast dealer.

And there's one of the people I was referring to. wink.gif

Nice perspective Mark! smile.gif

I would wait until we hear more information from the other pre-production samples that are being previewed.


Cine4home saw all the new models and didn't mention anything about them being dimmer than the current models.

Last Monday at JVC in Friedberg:
The Ultimate D-ILA compared X30/X35/X55/X70/X75



Area DVD also did a preview of the pre-production models compared to the current models as well.

regarding 3D gamma - did anyone else notice this?

"The two top models gamma settings of 2 points were extended to 9 points, wherein the two smaller models it remains at two points (A / B). "

I wouldn't worry about it. He couldn't find anything else to contribute and was tired of sitting on 32 posts. Seemed like a viable option to him at the time.

Im' guessing that it will help to understand the brightness of the SONY :

I've noticed an inconsistency in Kraines posted numbers. His posted Lux numbers do not jive with his posted Lumen numbers.

Perhaps Kraine can clarify.....

3.65m ~ 12' (this is near the close end of the zoom range and should result in near max light)
Hi Lamp ~ 470 Lux

and in high lamp mode 569 lumens
The lamp as 18 hours.
It's definitly less then the HW50ES in the same condtions.

106" Screen - is this diagonal or width?
12' Throw.....same as above
Hi Lamp ~ 569 Lumens
Lo Lamp ~ 387 Lumens

Assuming 106" Diagonal Screen:

106" D = 52" T x 92" W => 33.22 Sq-Ft

Lumen = (Lux * Sq-Ft)/10.76

-> (470 * 33.22)/10.76 = 1451 Lumen - This does not equal 569 Lumens
-> (302 * 33.22)/10.76 = 932 Lumen - This does not equal 387 Lumens

Assuming 106" Width Screen:
106"W x 60"T = 16:9 => 44.17 Sq-Ft

Lumen = (Lux * Sq-Ft)/10.76

-> (470 * 44.17)/10.76 = 1929 Lumen - This does not equal 569 Lumens
-> (302 * 44.17)/10.76 = 1239 Lumen - This does not equal 387 Lumens

Maybe... if you don't have anything to actually contribute here you should go back there.

So what PJ do you own? I noticed in your posts you like to spray to all fields.

"Zoom mini 3m65 distance 470 lux High Lampe mode
Zoom max high lampe mode 144 lux"

Not to mention the above is a ~70% reduction in brightness basied on level of zoom used?

I know that should not be right...

RS45 (previously Epson 5010) and Panasonic TCP65VT50 and TCP55VT50 (plasmas if you are so informed)

With Darbys (of course)

Does that "qualify" me

GaryB from JVC UK has just posted some measurements taken from 2 random X30 they have, plus a later X35 sample:
Quote:
I've just carried out some very quick checks on a couple of random X30s followed by our latest sample of the X35. At the centre of screen in our workshop test room using the white screen from the Service Menu after a 10 min warm-up we got:

X30 - 520 lux
X30 - 500 lux
X35 - 545 lux

Just FYI, the colour temp on the X35 was 6476 degrees.

Both of the X30s had less than 50 hours on the clock.

The X35 we have is a pre-production sample. I understand from Japan that the one tested by Kraine is somewhere between engineering sample and pre-production.

For those who want to view the thread post # 77 onwards (just waiting for confirmation of screen size), but shows a slight increase over the X30, which is promising.

http://www.avforums.com/forums/projectors/1678363-hands-exclusive-jvc-launch-dla-x35-x55-x75-x95-d-ila-3d-projectors-3.html

Updated the screen size is 83" diagonal.

Yeah it qualifies you in that case as a fellow projector owner.....as should have thought it through better before throwing out a "JVC fan boy" blast seeming to enjoy our angst once again over JVC lumens, and being on the pre-order list to plunk down good money again for a new machine. Odd sense of humor if that's not what it was.

Updated the screen size is 83" diagonal.

For those of you who panicked and experienced loss of breath can breath a deep sigh of relief. The JVCs will be as bright or slightly brighter than before. cool.gif
post #169 of 795
Bare in mind that the X55 will be slightly less bright due to the Eshift that the X35 doesn't have, but that's 1300 lumens verses 1200 lumens according to the specs, so should only be about 8% less if taken at face value.

I want to be able to run my X35 with the iris clamped down enough to give me 12-14fL on a 1.5 gain 112" wide screen which my current (300 hours on the second lamp) RS10 can manage without fully opening the iris. These figures look like I'll be able to do that, at lower lamp power and still not have the iris closed down plenty for a nice contrast boost over what I have now. cool.gif
post #170 of 795
New wire grid you mean not eShift2...... but that's supposed to help ansi, not reduce light is it? Well sorry if I threw that out there too quickly....... does eShift in fact reduce light a bit over 1080P display?
post #171 of 795
I don't want to add any fuel to the low lumens scare, but IIUIC the Eshift (1 or 2) has an extra part for the light to pass through so this is (possibly) what causes the 100 lumes reduction in light output on the specs of the new (eshift) models and the older (eshift) ones too for that matter. I don't know if the improved wire grid does this, but I thought we had ascertained that the X55 doesn't have the improved wire grid (hence the same 50,000:1 contrast claims as the X35) so I don't think that is the cause.
post #172 of 795
The X35 and X55 share the same light engine according to JVC. Yet, the X35 is rated at 1300 lumens and the X55 at 1200 lumens.

So why the discrepancy?

Manni first asked GaryB to confirm and Japan confirmed the numbers.

Ergo, the difference in lumen specification is due to either the CMS or eshift lens (there aren't any other differences that we know of).

The improved wire grid has nothing to do with this (both machines share the horrible unimproved wire grid tongue.gif ).

post #173 of 795
Whoa....I thought it was 1300 lumens for the X35 and 1200 for the models above it? So maybe it is eShift.

I think you're correct on this having seen the UK brochure on the same thread I linked to earlier. smile.gif It says 1300 lumens for the X35 and 1200 for the X55/75/95. The light engines for the X35 and X55 are similar (ie not the 'improved wire grid), but the X55 has the Eshift so IMHO this is most likely the explanation for the small difference. If the improved wire grid made a further difference then the X75/95 would have lower light output specs than the X55, which they don't.

And I'm 100 lumens behind -- I've corrected my post.

The X35 has 1,300 lumens and the X55 has 1,200 lumens. The loss of 100 lumens is due to the E-shift. Nothing to do with the wire grid. smile.gif

While 1300 is 8% higher than 1200, and 8% brighter to yoru err "face", because of the way our eyes brain work, one will perceive only about a 3% increase in brightness. I doubt unless viewed side by side, the 1300 machine would look any brighter.

This is true Mark, but we don't watch projectors on here, we only measure them so the difference is important. wink.gif

Maybe you can talk with my lamp and convince it it's only be on for a few hours instead of the 600+ that is does have cool.gif
(although in this case it does have a laughable amount of time on it whilst I was measuring it.....lol.

I think I put maybe 50 hours on my RS10 when I first got into calibration. redface.gif Less though these days, takes me maybe 40 minutes doing the greyscale, gamma and gamut using my Lumagen & Chrompure and now I can do this automatically. cool.gif
