I have a question for the gamers here.
Hypothetical
If one plays a porn movie to get their girlfriend or spouse in the mood, is that considered gaiming? If so:
How would lag be measured then? Certainly not in ms.
How should the measurement be made and what is the metric?
Would the lag vary by projector in such an instance?
Would the measurement vary by 2D or 3D?
Thanks in advance for your thoughtful replies.

However, no projector-based home theater will ever equal a Kuro's up to 30,000+ to 1 CR and black level unless you have your home theater totally devoid of all other light sources (i.e.,no light coming through doors/windows, no room lights and even the panel lights from some electronic conponents may be too bright. With a front projection setup when you turn the projector off and with the room lighting the same as you use for viewing, then that is as dark a black as you will ever be able to get from your screen and any source of light in the room will raise the effective black level by reflecting light from the screen.

It is once again "over" the original reading of 180 lux in center in low lamp for 8.5' wide 16x9 AR screen area. It was at 182 this time, and as mentioned as high as 186 after 60+ hours. Aren't the 1st 100 hours supposed to drop the most in lumens? But maybe the only 10-12 lamp strikes for those 94 hours is keeping it fresh?

odd enough but i performed some experimentation late last night because i was not as impressed with eshift as i thought i would be. i turned down all MPC controls to zero across 3 of the eshift modes as well as the 'off' mode. when i flipped back and forth between all these eshift modes and the off mode i saw NO difference in the picture pixel structure from less than 1 foot away (though i would agree i did not see much pixel structure at all even with the eshift set to off). no effect on the pixel structure between eshift off and on. kind of disheartening. if i start increasing the MPC controls then i start to see a sharpening and can see some effects from 1.5+sw away. i would liken it to the darbee effect, though more prounounced (i had a darbee in line).
i unfortunately forgot to test if i can get this result even with eshift off but setting the MPC controls to something higher than zero.
all in all, i am wondering if perhaps there is something wrong with my unit's eshift mechanism. i can't believe people would be raving at the results if all units looked like mine. unfortunately i have used 3 out of the 4 hours on the AVS return policy allotment so am hard-pressed to do more testing. will wait to see other folks' impressions here and then likely give Mike a call tomorrow about what to do here.
anyone else test the eshift feature (with MPC controls set to 0) on and off and compare results?

Maybe I'm getting paranoid, but I checked mine today after about 30 minutes in my calibrated mode at -15 iris ( which was giving 100 Lux) and was disappointed to see that it was down to 92 Lux. However after about 2 hours I checked it again and it's back up to 100 Lux again and I'll probably check it again just before I switch it off later this evening. I'm only up to 25 hours so far done in three viewings (so only 3 strikes of the lamp), but I'm sure my old HD350 dropped a little bit in the first 30 hours when I put the second lamp in it, so I'm hopeful that the dimming will be nice and slow.
Did we ever confirm if the new lamp is DC or AC?

Lag in particular is a very real consideration for most who game to some degree and 80ms (which is what Zombie clocked the 46 at) is on the high side unfortunately.

But have left the projector running as I'm getting ready to watch Lakers probably getting their butts kicked again in NY on time shift. No spoilers please . Just checked it again for bleeps and giggles at 98 hours and it looked particularly bright with the white screen. 190 lux A swing of 20 lux. It does seem sometimes to pick up brightness with the long run times. It's not the meter, like I said the screen I could tell was popping. So that's 98 hours and I stay all around and sometimes over the original lux reading on low. Not sure what to make of it. Watch I'll get calibrated tomorrow and then all of a sudden the lamp's going to nosedive on me over and above what the calibration takes out.

Looking forward to first hand end user reviews of this new JVC, particularly with regards to 3D, brightness, and lamp life. All of the reason that I sold my RS40 and switched to an Epson 6010. I think that the Epson will hold me over until affordable 4K and/or laser/LED are out, but I have always liked my previous JVCs, so am still lurking in their owner threads.
BTW, I whole-heartedly agree with the posts concerning improvements from the 3DLUT calibrations with a Lumagen. I have the Radiance XS, Chroma 5, and CalMAN 5 Expert with auto-cal. Very easy to run through the calibration and the results are spectacular. PQ looked good before, but the new 125pt 3D color-cube calibration takes it to a new level. This additional feature has justified the original money shelled out for the hardware and software in the past. Kudos to Lumagen for providing new features at no cost. Very nice upgrade. If you can afford it, go for it!!!

I'm only up to 35 hours but my lamp hasn't dropped from the initial check I did at 1 hour last Saturday. I hope it's not too good to be true as if it could stay at this level for the next 1000 hours I'd be overjoyed (I'm sure this won't happen but it would be great if it did).

So hows it going so far... sounds good so far? I'm dying for Phil to put out that x75 review so I can give Mike the go ahead when I get my call (well... I already got my call earlier this week and gave it up to the next fellow AVSr!).

My son and I watched Quantum of Solace which looked superb (even if it's not my favourite of the 3 DC Bond films). Lamp still measuring exactly the same after nearly 40 hours run time.
Just as a reminder mine is the X35, incase I cause any confusion as this is the RS4810 owners thread, though similar enough I of course don't have the Eshift and my CMS is by Lumgen.

Focus... 99% perfect!
ANSI contrast biased on viewing... Slightly better then last years, Sony's are still better.

He's lucky, but not the only one like this judging by mine.

And lens focus the same as SOWK's....perfect. Waiting to hear from Zombie, or maybe he's posted by now....haven't got to his eagerly anticipated new model findings thread yet ..... headed there now
