That would actually be really useful to see Craig, if you're happy to post Chad's report. If you had it calibrated 6 months before, it should show perfectly whether there was any gamma or greyscale drift over that 6 month period, as I assume your first calibrator would have dialled both in correctly.

Sure, Cobra (a French chain of A/V stores similar to Best Buy though much smaller) can be trusted for displaying an accurate picture of a lamp for a projector that isn't even for sale yet...

Why would you trust the picture when the description is still the related to the previous models, including the previous models reference?

This is clearly a placeholder, the picture could be from any lamp for any model for any brand:

"Cette lampe JVC PK-L2615U est compatible avec les vidéoprojecteurs JVC DLA-X9500. DLA-X7500 et DLA-X5500.

Lampe pour JVC DLA-X9500. DLA-X7500 et DLA-X5500

Cette lampe JVC PK-L2615U est compatible avec les vidéoprojecteurs JVC DLA-X9500. DLA-X7500 et DLA-X5500. Il s’agit ici d’une lampe officielle JVC. et non d’une copie bon marché. Retrouvez les performances originelles de votre vidéoprojecteur série DLA-X grâce à cette lampe JVC PK-L2615U."

I'm not saying there is no change on the lamp. I'm only saying that this Cobra placeholder for a product page is the worst possible source to make that kind of speculation and then post it here as if it was fact.

This thread needs more facts, not more speculation.

Yes they are some bright like original, but you must buy "High Diamon" who is special for JVC and not they "Black Diamond" .Black Diamond is 3D universall glasses who works with JVC too but they are a bit darker compare to High Diamon and lighter than origibal Epson glasses if you have Epson projector.


They are incredibly lighter than original JVC. :-)

BTW, I appreciated your PMs, Woof. You have some of the best points of reference to report on the NX9. Depending on what you find, it may give me cause to wait it out or cause to cancel my pre-order. No pressure. Lol. I was contemplating getting a B stock RS4500 but didn't. I also don't have a hush box.

If you have a 1.0 gain screen at 120in diagonal, you'll need about 525 lumens for 12ftL. Which is low, many prefer 16-18ftL, which is 700 to 800 lumens. Factor in HDR, where you will need at minimum 25ftL, which will be around 1000 lumens.

Now using your screen that is 2.8 gain, a jvc can go as low as 200-250 lumens. With a 120in wide screen that is 2.8 gain, you'll get less than 10ftL with the aperture completely close. Of course increasing the aperture will give you more brightness, but it's almost impossible to be too bright. I have a 2.2 gain screen and appreciate getting 20ftL with 100k+ contrast on all my content.
Starting with the 400, 500 & 600 series forward, you can't get a lamp based JVC with new lamp down to 250 lumens, even with iris at -15 and longest throw.

If it has the power cable and the remote, then that is all a new one comes with. JVC like everybody else, stopped sending manuals, years ago. I think the year of the RS45 was the last year for printed manuals.

Weren't the Panasonic players condemned to 60FPS hell for streamed content? Or have they fixed that? That would be a big shame if you had to go to 60FPS with 3:2 to get colour/ luminance that works.

If the video is supplied with DV metadata then it may or may not be possible to calculate correct HDR10 metadata from the DV data. Especially HDR10 metadata that matches what the original master for blu-ray intended.

This problem is only going to get worse because more and more flat panel TVs are going to support DV. This may lead to the death of HDR10 metadata for streaming devices if they quit supplying HDR10 metadata.

It may be like the betamax / VHS wars. As a result, for streaming, DV may win and HDR10 just won't be available except on UHD blu-ray disc where it is required. Unless that changes over time as well.
I think it is "only" on AppleTV that DV has managed to really get a stranglehold, isn't it? Plently of other platforms stream in HDR10.
The Sony UBX800 UHD player does netflix HDR10 but it annoys me because it switches framerates during the previews which renders the UI almost unusable on a JVC with long sync times.

I'm not sure if I've said this in this thread or another, but there is nothing at all difficult about calculating MaxFALL and MaxCLL. The pseudocode algorithm is less than a page of A4 for both in the CEA spec. All that is stopping this being done properly is the will to do it (as Apple could clearly (if they wanted to) play the stream through the DV -> HDR10 conversion and pump the resulting frames into the algorithm, then store and retrieve at playback time the correct data.

There is much more to it than this though. There is a fair bit of content which works OK, which leads me to think DV converted could work fine, the problem is that there is either someone somewhere applying the wrong settings, or there is some version of encoder packs which creates broken streams. That Daredevil S1&2 are broken, yet S3 is fine, with all three being DV, says there are probably just monkeys at the wheels somewhere (either writing or driving the software).

I see, so it's likely a full production unit? How are they getting these?

Are you going to be updating the calibration thread with the new Autocal info for these?

And by the way, which of these new ones do you have in your sights?

If I recall a conversation with JVC at Cedia correctly, the lamp for the new JVC's is the same as the previous models, in a new housing.

Yes, this is my understanding too. This is not the point riddle was making. He was stating that the reason for the new delay was that JVC had to change the new lamp housing for the new models (as seen at IFA/Cedia) to a further modified housing, and he was using the picture of a Nec lamp housing from a placeholder product page in a French A/V chain which description still pointed to the old models to back this speculation, as it looked different from the new housing as shown on JVC's website for the new models.

Just another rumor. I'm sure someone from JVC is reading these, shaking their heads and thinking " what the hell are these guys thinking " ! Too bad there isn't a free RS3000 if you guess correctly, but that would just start a flood of rumors !

This is a mainly and Apple TV issue because they have a lot of DolbyVision streaming content. Since streams aren't required to carry HDR10 Metadata along with the DV metadata, Apple calculates the HDR10 metadata from the DV stream. Unfortunately for many titles the calculation is incorrect or it changes multiple times during a program which isn't allowed by HDR10 standards.

I believe the NVidea Shield has no problem with this but I also don't think the shield supports DV. Apple supports DV but has issues with HDR10 metadata calculated from that DV stream. HDR10 content on the ATV4k is fine.
While the Panasonic UB820 in SDR/BT2020 mode will output BT.2020 for Amazon HDR content, I find that Netflix outputs REC709.

The only way I can get SDR BT2020 from Netflix is to turn on the SDR/HDR conversion option in the UB820. But this also results in all Netflix SDR content being converted to HDR that I don't want.

I heard they were implementing a new security cam feature to cut down on theft.

I hear they are adding an " auto crap mapping " feature, that gives you a blank screen if you try and project content that got below 35% on Rotten Tomatoes ( to protect your eye sight ).

I'm confused by your post with regards to obtaining Netflix HDR content as SDR/BT2020. Could you please re-state the settings that you use? The problem is that the RS500 doesn't show the actual color space, only whether or not the HDR flag is present. I didn't appear to have any success in getting SDR/BT2020 when the Fury was in the chain for Apple 4kTV or Roku, as prior posts have indicated that those streaming devices weren't capable of remapping HDR -> SDR/BT2020. BTW, did the Panasonic 900 have the same capabilities as the 820 for streaming media? Thanks.

Aside from too much brightness for SDR, the other question about this screen is whether it can resolve full 4K resolution due to the high amount of texture and grain. On my small 106" sample, the glass beads are very noticeable even next to the larger 1080p pixels. Never tried a 4K projector on this material to see how much the texture interferes with the smaller pixels. Of course the larger your screen (and pixel size relative to bead size) and the farther you can sit from it, the less noticeable any issues will be.

Also, people shouldn't assume owners of this material necessarily want a blindingly bright image. Some of us bought these screens more than a decade ago when most projectors were extremely dim compared to today. If I end up keeping any of the newer brighter projector models in the long run, I may replace this screen with something smoother and more transparent. Unfortunately, can't go bigger due to room size limitations.

That's a good point. I have a gut feeling that it's going to be okay, as I don't even notice any glass beads on my screen when I'm standing really close to it. On my particular screen, the screen material is quite smooth. And my seating position is pretty far back. But I'll really have to see what it's like when I have the projector and everything set up.

BTW, what material is your sample? Is it a Da-Lite HP from way back in 2007? If so, you're more of a pack rat than I am.

I've had this screen since 2003. It's the original 2.8 gain material. It also has several "hot" beads that appear to be 10x brighter than the rest of the screen. You need to to be sitting in just the right position to see them and displaying brighter colors. Like all screen materials, there's always some trade-offs that made sense when I purchased it. Most of the information online claimed they were discontinued due to inconsistent quality. Maybe mine is a dud.

I had a High Power for a while, and those " hot beads " would occasionally beam at me, like a tiny lighthouse. It a quirk of those screens.

I understand Mike, but nothing was wrapped in plastic bags, cable ties for the power cord, etc. Its the packaging, or lack there of that makes me think it is a road show piece.

So are we expecting anything from JVC USA today or is it pretty much now waiting until next week. So weird that European and Japanese dealers have pushed back their dates into mid December and nothing from JVC USA. Asia and Europe gets prototypes to review and pass around like fruit cake...they get updates on delivery times and we get nothing. Throw us a bone here JVC. Somebody has to know something
