If you find the Standard color profile doesn't fit the bill, Custom 1 typically does (only available in user picture modes). Or you can load the 709 profile that Manni created a long time ago in his calibration thread. Cutting your light output by as much as 20% for less than 1% gamut coverage seems rather silly to me. Typical dE's for 709 at 100% saturation on a calibrated JVC is well below 2 and typically below 1. Usually the only issues are the hue shift in 100% green and saturation tracking above 60% with red.

I owned a N7, after I applied Arrow’s custom gamut setting, I have to agree that there is negligible difference between a BT 709 (projector default) versus the custom gamut. As such I revert back to BT 709 colour profile for my SDR.

Absolutely not. The lens cover was nice, but you really don't need it. My rs4500 and none of my Sony's had the auto lens cover.

Not mine... @Javs

Personally, I won't be using the color filter with SDR and I don't recommend that laypersons do either. If you read back in the thread you will see that I have been quite vocal about this

Entirely possible that I don't understand!
You can still set manual iris levels on the N5. It will just set the maximum that the dynamic iris can open. I seriously doubt this will be a problem for anyone.

Does anybody have any information on when the new units will really start shipping in the US? It seems like a few trickled out, and the ETA for a significant number of people getting their units is anywhere from a week to a few months (and that's pretty much an assumption on my part). Is something going on at JVC, like they have backlog of untis to QC or something? Does anybody have an idea of what is going on or rough timeframes?

a. Sony VPL-VW385ES
b. JVC NX7
c. Benq HT9060

The Sony is native 4k and isn't a DLP (so no rainbow effect). My questions are about the JVC and BenQ. They both are DLP, so...
1. They both may have the so-called to rainbow effect...right?
2. How are they achieving native 4k if there is no native 4k DMD available from Texas Instruments? Are they using something else?

The Texas Instruments DLP660TE has a 2716 x 1528 micromirror array.
http://www.ti.com/document-viewer/DL...ct#DLPS0721610

The BenQ clearly shows this on their features page, although the JVC doesn't. My apologies if this has already been answered in this thread somewhere.





Huh? Since when JVC becomes a DLP projector unless you are talking about the entry level JVC which has a DLP tech? If you are talking about the NX series projectors, all of them are using DiLA. It’s actually a LCoS. Same as Sony but implementation is different between JVC and SONY.

I will make your MKII dolby atmos DIY project for myself, but before start to working on that, I need to choose a center, rears and back speakers also. I just want to match them all, but honestly I dont have enough knowledge and experience. My fronts currently JBL E80s and my receiver is onkyo nr686, can you help me to which path that I have to follow please? I already open a thread about all my project steps on this thread plz check it... (https://www.avsforum.com/forum/155-d...rus-audio.html)

Thank you

rifat

PS: I guess it will be my 13th post I need 2 more post after that I can send you PM

U need download the JVC autocal software. Download the ver 11. Then got to Import/Export option to load in the custom gamut profile.

But before that, make sure u power on your projector and connect the Ethernet cable between the projector and the laptop/PC (this is one method). Next select the picture mode of your choice and colour profile first before hitting that Import/Export option to load the .prof file.

The JVC app of course throws a connection error at this point. The HDR mode was completely screwed up after this since it wasn't loading the full data and I ended up just running a new autocal to correct it. I guess it's not the end of the world that I can't restore this as I'm having it professionally calibrated in a few weeks but still very annoying.
The restoration process on my RS4500 took about an hour. I'd make sure your network connection is super stable. Are you perhaps using wifi?

I wouldn't let the exclusion of an automatic lens cover in any way, shape or form bother me or influence my purchase one way or the other though.
I have had good luck using an eye glasses cloth. I only had to clean the lens when the projector was new so far. It seemed to have some guck on it. Gently wiped it down with a dry eye glasses cloth.

I mean who is seriously going to be "blinded" by 450 lumens of output? That's really dim even if your screen is only like 90".

JVC have been made aware of this!!!

As your unit is an N7 its obviously not just related to the NX9..
I really think you should post the steps to repro this. It's important for people to know what *not* to do. Preface it with "do not do these things" or something. Lack of information is more dangerous than providing it.

I think you should look for @GregCh posts on this. He just upgraded from a 385ES to an NX9. The NX9 and N7 will be very similar. So you can get an opinion from an owner of both basically.

Here are a couple of things I noticed this weekend:

1) Lucy 4K DVD playing through the Pani 820 tone mapping to my DLP projector was STUNNING. Man if my RS2000 is even better I can't wait. Get it for a test disk if you don't have it. I got mine from Amazon for $12
2) I had to turn down my brightness on my UHD65 4 notches because it was too bright. I am getting 38Nits on my StudioTek 130 with the projector 19' from the screen. I can't imagine what it will look like with the RS2000. Not sure how 50+ would look like. I may need to wear sunglasses. I think this may be a good argument for bias lighting. I may try it sometime.
3) If you have an Oppo 203 and getting a Pani 820 to go with your new NX projector hang onto the Oppo for a little bit. The panni had trouble with a couple of disks and I had to use the Oppo
4) Installed my new Chief mount for the new projector. That mount is rock solid and I highly recommend it. Much better than my other projector mount.
5) Last while looking at my empty mount someone reminded me that MANY weeks ago it was stated that JVC said it will take until at least the end of March to fill all the back orders. Depending when you ordered it may be in the next few weeks or it may be end of March or first of April.....they must have sold a lot of these things.

Home Theater: JVC RS2000, Stewart 120" 2:35 StudioTech 130, Panamorph DCR Lens, B&W 802 Nautilus, HTM1, 4-B&W 805's for surround, 4-Martin Logan 22's ceiling speakers ATMOS, 2- PB-16 Ultra Subs, Marantz 8802A, MacIntosh 8207 AMP and Proceed AMP 5, Panasonic 820, Apple TV, XBox One, HTPC with MadVR, Qnap NAS

That is a valid reason too. Mike how many units have shipped so far? I've counted roughly 9 folks who have posted that have new NX9/RS3000 units. Though Arrow's wouldn't count for USA deliveries. Included in those numbers are 4 October 2018 built units with one December 2018 unit and 4 that I don't know build dates on.

While technically true that they aren't making them fast enough to meet demand, it is also technically true that *I* am not making them fast enough to meet demand.
It does seems like they aren't making them very quickly. I was an early September RS2000 order and mine is supposedly shipping this week some time, amongst the first batch of RS2000s to go out in the US as far as I can tell.

I believe that for new orders. However, I was told on Friday that my NX7 has arrived in Canada with a batch of other preorders and after clearing customs and going through a 1-2 day quality control check it would be sent to my dealer for pickup either by the end of this week or at the start of next week. I placed my preorder first week of November.

I would question that. It appears that JVC has made a conscious decision to bring their high end to market first; at the expense of the mid-range and low end. At some point their goodwill in the marketplace will evaporate. Speaking for myself, I am close to bailing. This kind of wait is fast approaching ridiculous.

Hmm, seems that they just have scattered the units already built last autumn, and the units from the new massproduction havent reached the markets yet? (Not in significant numbers at least).

In Europe not many unit have arrived to customers.

Same here, curious about that statement. Is there any documented proof about an extra iris and if so, which settings are there integrated for that extra iris.

The N7 and NX9 have a lamp iris and a lens iris. The lens iris is used in dynamic iris mode. The lamp iris is used when you set a manual aperture. If you go to the manual iris setting and start at 0 and work back towards -15, every other number will move the lamp iris. The lens iris is moved on the odds, the lamp iris on the evens. This is the only time the lamp iris is moved.

The N5 only has the lens iris that works the same way and also handles the dynamic iris behavior.

Add me to this list. I've asked on a couple of occasions for current owners to explain how that 2nd lamp iris works. Does it contribute to the dynamic contrast or is it just a fixed thing to allow for lower brightness.. how it is controlled (perhaps take a pic of the menu option)?

From what I've read on here and the anticipation thread is:

1) it is NOT the reason why NX7 has a "native' contrast advantage over the NX5 (i.e. 80,000:1 vs 40,000:1)
2) it is preferred for SDR content if your room is going to be too bright.

There is no direct control for the 2nd iris. The menu on the N5 and N7 will look identical. You have aperture, under the picture menu. And it's a slider where all the way to the right is default and considered 0. If you leave the iris in "auto2" or "auto1" mode, then the lens iris will be working dynamically based on content to increase contrast. The lamp iris is fully open.

If you set the iris from auto1 or auto2 to "manual", then the slider can be moved by you. The more you move it to the left, the darker the image. The lens iris moves on the odds, the lamp iris on the evens. If you leave it set to some point then set the iris back to "auto1" or "auto2", then the lamp and lens iris will be left there for max brightness and the lens iris will still clamp further for darker scenes for better blacks.

On the N5, it has no lamp iris, so everything is exactly the same except there is only the lens iris that does all the above. You can still get very dark with just the lens iris.

If your screen has high positive gain (like some folk on here are using) then yes, it is quite a bit too bright for reference SDR, you can put the numbers into a calculator and see what you get with 2-2.4 gain . If you care about having reference levels your only options then to reduce brightness are to strap an ND filter on the lens or to reduce the brightness digitally, losing some contrast. Neither are particularly good options so for small, high gain screens the 7 and 9 series are a better bet. Even then I recall one poster saying they struggled to get it dim enough.

It is at least part of the reason for native contrast differences between the 5 and 7/9 series units.
The lamp iris is (or at least was, in the previous series) a rectangular "window" that becomes wider as it opens and narrows as it closes. This cuts down the light going through the light engine, starting with the stray light at the outside edges. This stray light reduces contrast.

On my X7900 by being careful about shutdown sequence my projector seems to be tricked into leaving the lamp iris in the wrong place, which lets you do some experiments.
For example, at -10 iris the lamp iris appears to be responsible for around a 10% reduction in light output over when it is fully open. But is also responsible for about a 20% increase in the native contrast.

There is a writeup of the traditional JVC 2 iris solution here:
https://www.avsforum.com/forum/24-di...n-writeup.html

Until someone interested in such minutiae takes it upon themselves to document down to this level, assume most of what is written in there stands. For now one notable change seems to be the addition of a different "closed" or "max" level for SDR and HDR in the new projectors. @ARROW-AV has also noted what appear to be more "steps" that the DI is able to be set to (in the X7900 at least the DI control levels seem quite rudimentary), which probably helps in hiding the operation of the DI from the user.

Hello everybody,

Here in France, some people started to get their N5 projectors and they notice a long time between the switch on and the D-ILA logo appearing on the screen.
So far we have 2 reports : One with 1'55" and another one with 3' !
It reacts as if you use the "hide" button from the remote.

Firmware is 1.18

One of the user also reports a black out of the picture after 20 minutes (happened once), it looks like the iris is shut/closed.

Do any of you happen to experience these long time before the D-ILA logo show ?

We are waiting for reports from another guy who got his N7 yesterday.

Thanks in advance for your feedbacks on this matter.
