Red vertical goes in opposite directions on either side of the screen...

e.g.
Red vertical left of screen is to the left of the white vertical
Red vertical right of screen is to the right of the white vertical
Red centre of the screen is correct with white vertical

If you correct the right hand side of the screen the left side gets worse etc etc...
Only zone convergence can even this out. The panel(s) are slightly rotated in some way relative to each other which causes this.

Yea you have to either decide it's not bad enough to be a problem or you have to fix it with zone convergence.

Does MadVR have convergence correction? If not, that is a function that could be useful since the interpolation used in the projectors can surely be topped with better algorithms.
No, madVR doesn't have a convergence correction. But you'd be surprised just how well zone convergence actually works in real content. I think correcting with zone convergence is better than leaving the problem, if it's as bad as you say.

Try this. Make a copy of your lens memory as is. Then select it and adjust zone convergence. Then you can toggle between the two lens memories. One will have zone one won't. You can see which one you like better.

It's really strange to me that putting a filter in front of the light path could somehow give you a wider color gamut while blocking some of the light. I couldn't find any videos or technical documents really describing what a color filter does.
This is related to the old DCI Xenon lamp based projectors, but it is same principle.
http://www.loreti.it/Download/PDF/DM...CinemaTalk.pdf

Basically:
The lamp spectrum includes much more yellow light than in needed for D65.
When you split this into RGB to send to the panels this yellow light is still present (most gets left in G channel, some in R).
When you look at CIE diagram you can see that if you add green to yellow it brings the green further in towards yellow (away from the DCIP3 / REC2020 primary). If you have no way of limiting this yellow light then this limits how far out your green primary can get.
The yellow notch filter removes the yellow light, which allows the green primary to be further out.

I understand in the DLA-X series the filter is only in the green light path. In the new series the filter is in the red and green light path.

Depending on the exact match between filter / lamp / processing you can find you only have tiny CALIBRATED losses for filter in place. On my X7900 I only lose around 3% calibrated light output, because the extra light removed is mostly yellow which was unusable for D65 whitepoint. To truly know the losses due to filter though you need to turn off all the colour management in the projector (using profile off and forcing the filter into the lightpath using the D3 IR command) as the colour management in the different modes can also be responsible for some light loss.

This is encouraging.

The other complaint that has been reported on the new DI is that it doesn't close down on fade-to-black as small, or as quickly, as with the previous generation of JVC's. The net result is that the FTB isn't as effective as with the prior ones.

Has this new firmware resulted in better FTB performance, as well as addressing the yellow/gamma shift issue?

Hmmm. JVC just released 2.01 and we just updated it last week and now 2.04 is out. So when can we see this latest 2.04 be avail for existing users to update?

I'm very interested in this also. Since I am in Europe, I am also interested in knowing if there are any differences between US and EU firmware. I think it is not, but it would be nice to find out for certain. I ran the V2.01 update (I guess US version) on my N7, no problem.

Hi all

First post and fairly new rs1000 owner here, but I've lurked on the forums for some time. Had a few small hiccups with random vertical lines across the image requiring shutting down and restarting PJ but not a deal breaker. Assuming software will fix, no issues with image quality whatsoever.

I am however, having issues updating from 1.9 to 2.01 (and assuming issues updating to 2.04 when it's released as well). I've tried 3 different flash drives thus far all completely formatted to fat32 and followed the procedure for updating, but i always receive the "USB flash drive cannot be recognized" message. This was after my search for help on the forums (trying different flash drives).

I've tried quick formats and gone into disk manager in Windows and performed complete wipes of the flash drive as well with zero luck.

If anyone has a specific brand flash drive, not that I could imagine it'd make a difference, I'm all ears. Any help is greatly appreciated!

What size is your flash drive? I've had issues with other equipment (in the IT industry) that won't recognize drives above a certain size.

I thought that might be an issue as well. I've tried 2, 4, and an 8 gig flash drives all with same result

I had this same problem. I went through two before I found a third that would work. It was a newer drive. That’s the only difference.

Make sure you have the unzipped folder in the root directory.

Let me just say how impressed I am that JVC is doing these fixes so fast. For some it may seem a while but as any software engineer knows when you fix one thing you can break two and need to fix those also so it takes time. I can't think of another projector company that has responded so fast to issues. That in itself for me outweighs some other things I may like in another brand. Not to get off topic but I see all the conversation in another thread about the BenQ990 and my biggest concern is that it is a Church/Business projector market not a home theater projector so things we may need they may not fix. My Optoma you need to actually mail in to get a firmware update. No way I will ever get a projector that you need to do that with again.

Keep it up JVC

Thanks, it's definitely unzipped and in the root directory. I'll dig up another flash drive it keep trying!

Per the instructions, the flash drive should be inserted while the PJ is off and turned on with flash drive already inserted. I've followed those instructions but i'm really curious if that matters?

Mark is that just issue with this line - I have noticed as well an overall raising of black floor with HDR- Contrast is friggin amazing on SDR on my setup so it noticeable-
Its not just open iris either- even if I close iris to same level in HDR as I have on sdr (-10) its just overall brighter floor - as well bright corners are way more present with HDR material-
hardly any with SDR

Are there many RS3000 (NX9) in the hands of forum members yet? Hopefully, once the various concerns are worked out (software, quality control, etc), we can get some impressions of how the "big lens" is working out.

Quite a few forum members with RS3000/NX9's. Those were the first JVC's to ship.

Totally agree! Mortal Engines was the best 4K movie I have sent to date.

Lucy, Jumanji and The Greatest Showman were all really good as well.

I loved Mortal Engines. The 4K disc is incredible. It's my main go to disc with Lucy in second.


The dynamic range in Mortal Engines really shows what these new projectors are made of.

That is true, firmware updates do not come out that fast usually, especially back to back......

It worked for me with plugging in the stick while the projector was running and selecting update in the menu.

Red vertical goes in opposite directions on either side of the screen...



e.g.

Red vertical left of screen is to the left of the white vertical

Red vertical right of screen is to the right of the white vertical

Red centre of the screen is correct with white vertical



If you correct the right hand side of the screen the left side gets worse etc etc...


I have the same thing on my 1st rs3000 that i received. Jvc said this is considered to be within spec and to use zone convergence. They did agree to exchange due to a very noisy DI. I’m currently evaluating my 3rd replacement unit. Jury is still out.

One thing i will say is that the lens on the 3000 does appear to need a few hours to break in. Eventually, convergence improved drastically and i disabled all corrections. Also, dont even go pixel peeping until the lens has warmed up for about an hour.

Not sure if this video has already been posted.

Here's one of my favourite AVS posters, who calibrated the JVC for the demo, commenting about the projector (Kris Deering) along with SpareChange.

Edit: Looks like it has been posted so for those who missed it (like me) here it is again.

Per the instructions, the flash drive should be inserted while the PJ is off and turned on with flash drive already inserted. I've followed those instructions but i'm really curious if that matters?
Make sure the actual folder is placed in the root directory (not the files directly) and correctly named.

Yep, extracted and copied the exact folder (no changed names) to a freshly formatted flash drive (fat32) in root directory.

I'll keep trying other flash drives, just thought I'd see if anyone else is experiencing the same or had any other tips.

Appreciate the help

I think a lot of this has to do with the black floor on the signal coming in, I know when I had problems with this simply lowering the brightness setting on the projector down to -3 or so would get the DI fully engaged with credits and openings like that.

hardly any with SDR

Hmm maybe this explains why I’m not still seeing this problem as I’m mapping HDR to SDR in madVR before it goes to the projector, but when I was sending HDR to the JVC lowering the brightness level fixed this for me.
