JVC RS1000 / 2000 Anticipation Thread

[Cine4Home]

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.

Looking for some adult sanity over here!

I'll just wait till Seegs, Zombie and Kris get their projectors for reviews!!

The only thing I haven't seen yet "over there" is snarky little gamer 'its asking for lag times!!!

i always get confused with what max zoom means

if 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?

So at CES yesterday I made a point of having JVC shut the door and turn the audio off. The RS3000 is really quiet ! It seemed quieter in high lamp with 4K HDR than my RS600 was in high lamp. Just FYI. And I my face right in it's face - so to speak.

Being at minimum throw with the lens zoomed near maximum gives you more light / lumens and less contrast. Being at the longest throw will reduce the lumens but increase contrast.

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?

It is broken and I think it has something to do with the gamma modualtion and to me it looked as it did many wrong things even with the manual iris set to 0. But I only had a short time with it...

[Andreas21]

It measured 160 nits on a 110" 1.0 gain screen with the iris set to 0 and high lamp mode. This was in one of the user modes and custom color, grayscale and gamma (set to 2.3 measured at 2.4). I did not measure the brightest modes.

The contrast numbers i posted is calibrated numbers. 160 nits if brightness is uncalibrated, calibrated it was around 145 nits.

No, that was at mid zoom.

[Dylan Seeger]

Boy, I'll tell ya, some people act like a skittish animal. As I mentioned before in this thread, JVC seems committed at making their projectors function properly. They have a proven track record at releasing firmware files to fix issues, especially related to the dynamic iris. I saw at least one person has cancelled their preorder due to what they thought was an issue that's already been fixed. Now he has to wait at the end of the line if he wants to get a new projector. All I can say is any projector when thrown under the microscope will show issues. Most of these microscopic issues cannot be detected with normal video content.

Everyone calm down and take a deep breath, JVC will makes things right in the end like they always do. I see we're now getting a free lamp from this whole ordeal, so there's one positive thing to look forward to.

[AVSMike]

Yep, JVC already has new firmware for the iris.
