Jamnik, you should be getting about 1570 calibrated lumens in high lamp and about 1150 to 1200 calibrated lumens using low lamp, on a new lamp.
Here's an interesting tidbit for you all --kind of a head-scratch'er for me. On my 695ES, after reaching the 200 hour mark, the image actually got brighter.
Is that even possible? I measured contrast too and it was reading higher than when I first got the machine, presumably due to the higher top end reading. (By the way, I also had turned off the auto zone alignment in the service menu before that...but I don't see how that could be relevant to brightness increase.)
I'm using a Stewart Cima Neve 1.1 gain, 125 inch 2.35:1 from a throw of about 17 feet.
Nigel, for comparison's sake...as we await your findings
, here are my numbers at the 200 hour mark.
Picture Mode: Cinema 2
Contrast Setting: 96
Brightness Setting: 50 (default)
ANSI Contrast: 420:1
Iris wide open/DI off, Full On/Full Off Contrast: 9,125:1
Iris Clamped down/DI off, Full on/Full Off Contrast: 19,000:1
DI turned on: I know the 695ES is spec'd at 350,000:1 with the dynamic iris engaged, but the best I could get was 77,180:1.
My room is light controlled and blacks on my unit look very velvety; I have no complaints even coming from the black level reference, the older JVC, X990. And I have to add that the dynamic iris function on the 695ES is so invisible: no pumping, no brightness compression like on my past JVCs, and gamma tracks so well so that it doesn't melt away once the iris is doing its thing.
But the best thing about this projector, to me at least, aside from its three-dimensional look (high ANSI contrast maybe) and sharpness, is its processing of motion and motion handling in True Cinema. BRILLIANT!!!
I get the whole 300 lines thing. But on my past JVCs, for example, whenever there was fast motion sequences, I felt that motion was smooth but I was missing part of the content that was being somewhat smeared. Not so at all here. Hopefully the new JVCs are on par. I'm guessing it's the X1 processor and the responsiveness of the Sony panels that are helping here. Nigel, please test motion in true cinema too.
