I see one NX9 owner is saying his unit measures in at roughly 30,000:1 at the telephoto end of the lens. I'm hoping most of the other units measure this way too. Hopefully only a small loss after calibration.
You mean NX9 with longest throw? I would assume 30,000:1 realistic yes, but with light loss and maybe ANSI loss due to the zoom of course.
Yes, the lens using the least amount of zoom possible. Usually this is a contrast number I provide when reporting on/off contrast. That and the amount of contrast available using maximum zoom.
i always get confused with what max zoom meansif im at minimum throw distance but have the pic zoomed all the way in....to create the largest screen possible....is that max zoom? and negatively effect light and contrast output?
Yes that's max zoom. The opposite is true for minimum zoom. Max zoom normally means lower on/off contrast, the most lumen output and most ANSI contrast. Minimum zoom normally means more on/off contrast at the expense of lumen output and ANSI contrast.
A friend of min got an NX9 yesterday and I was over to look at it today and it looked good apart from a few small details. We also measured it at Max zoom to 29000:1 and at -12 to 90000:1 and -15 to 115000:1 so he has a good sample when it comes to on/off contrast. It was also like all new JVCs close to perfect out og the box as soon as we set the gain in the PJ. What I find dissappionting is that JVC ships out these projectors after quite a long delay with a bug so that the DI does not work at all.We will do a side by side test with my Cinecersum BW2 soon and then we will be able to measure it at longer throw.

From what I've read it seems the bug occurs only if you're using a manual iris setting past fully open. Is that true? Are you forced to use the iris fully open to get the dynamic iris to work?
Thanks for the update. Do you have the matching lumen results?
