Ideally if you do single pixel adjustment and can't see the convergence issues from a few ft away then leave it. The colour shift in greyscale however can be seen from very far away.


Without zone adjustment the pattern would not look as good. I can’t use a single click do to the nature of my convergence issues. Itnis fine at center. On the left side of the screen, the white vertical lines show a very visible line of red to the right side of the lines. On the right side of the screen, the red line is on the left side of tue vertical lines.

Can you elaborate on the greyscale shift and why zone and fine pixel adjustment messes with it?

I am mainly going to assess sharpness and focus uniformity.
My RS4500 I got today doesn't have perfect convergence either. I let it warm up for 2 hours then did a zone alignment on RED and looked hard for the artifacts caused by zone alignment and honestly see none. Now the convergence looks great.

Also on focus, one way I was focusing the RS4500 today is on a pure white screen at 1 foot from the screen looking for the pixel grid and just focusing to make sure the pixel grid is visible all over.

Some zones needed 8 clicks to get red in line and on average i would say 5-6 clicks per zone. Flipping back and forth from on and off for pixel alignment on the qbf pattern did make a noticeable difference, especially for white on black text. With pixel align on, it appears to be a tad bit sharper. Please note, i was limited to 4k 444 at 8bits.

Is there a test pattern that can show the color shift?

Hopefully you get a good sample. PM me when you've had a chance to test yours out. I'd like to hear your thoughts.
Will do! Still confused with the tone mapping feature. Hopefully I will get some benefit vs what I was already doing with the integral.

Here is something for you guys to test out Check the low end.

I found it to be to bright. So Brightness need to be turned down to -3 to -4.
If not this is done you measure in 2.4 gamma liniar from 5-100% gamma 2.4 but 0-5 % like this 1% 2,1, 2% 2,15, 3% 2,4 4% 2,4 and 5% 2,4

Then you get very much noise in the dark end of the picture.

Just need to verify if its like this with all units out there. Have tested this with 2 units with same result. You actually see it on test patterns. That its to bright and that you clearly visible even form sitting position, you see bar 17 way to bright in brightness patterns.

Projectors JVC NX9 :) , JVC X500, JVC RS400, Cine9

Colorimeter: Klein K10A, Spectroradiometer: Jeti 1501

May be your first projector but its not your first display devise. There are pros and cons to every machine made, they all have flaws, you just have to pick the right machine for yourself and the flaws you can live with. JVC has proven thru the years they make the most solid projector while providing the best picture available which will last thru the years. These units just came out and we have no where near the user feedback needed as of yet to really pass judgement.

Its not greyscale solid colours its actually fine textures in greyscale, your images honestly dont show much of an issue there... You can see it here, there are a bunch of differnt colours appearing when it should all be grey. Thats visible from miles away to me anyway... But honestly it doesnt show up much in content.



If you are happy with your adjustments then leave it. I generally dont and wouldnt use Zone though, but thats me. I would prefer to pick a full screen adjustment that is the lesser of all evils rather than do zone.

Looking at your images, it seems like your lens is pretty good! The text is not overly blurring in any one place vs another at least from these images, you dont seem to have text fringing and bleeding. Looks good man.

At an implementation level; I'm not sure how familiar you are with the workings of these projectors. The root cause is that one or more of the panels are fractionally mis-aligned in some direction. But there aren't any mechanisms hooked up to the pixel adjustments that actually move the panels. All the adjustments are achieved by modifying the pixel values.

If you have a uniform full (or close to full) pixel mis-alignment in one or more channels then you can just "slide" all the data for that channel in the correct direction. This is a good solution.

However, this doesn't address slight misalignment, which is where the fine adjustment comes in. You clearly can't slide a whole pixel a small amount on the panel; and I'm not sure exactly the algorithm used, but basically I think a small proportion of the R or B pixel value is slid into the adjacent pixels, depending on how high you dial up the settings. This counteracts the mis-alignment to an extent, and works reasonably well so long as you don't have a very fine pattern of alternating lines as then the "trick" used becomes obvious.

The reason zone adjustment is less favoured is that this applies varying amounts of this pixel value "sliding" in areas around the screen, giving you areas on screen now which are being treated distinctly and much more chance of spotting the trick in action as there are now edges to the "trick" in the frame, which might be revealed by the content. Test images will very quickly expose it, and depending on the usage scenario (eg PC desktop / graphics / device menus /etc ) you might well spot it in action.

This is a good explanation, but I've done a pretty good zone alignment and it looks great in real content, desktop, text, games I can't see any evidence of it anywhere. When I zone aligned my sony, I remember having greenish splotching all over light grey patterns. And I remember when I had like a windows explorer window up and moved it around I could find spots where it was greener than others. That seems not to be the case here.

Figured rs4500 too big, didn't think about these hitting limit. Ah well, not full race harness, but at least wearing cute little lap belt for last leg of journey.

Agree shipper could still have a "head on crash".

One good thing about delay past holidays: UPS not using all the extra young kids, er "runners" they employ during rush to throw packages, er "deliver" onto concrete porches lol My sons friend (who can break anything) actually got uniform, but luckily for customers rush was over before he started lol.


Sorry for diversion. Thanks for heads up.

Let me start off by saying that I don't know the answer, but I have read contradicting posts on this subject. The majority have said something along the lines of what you do here, that any use of zone correction will have overall negative consequences. But I also recall reading the opposite, that despite many recommending not using it, there is really no harm with zone adjustment.

Has this been demonstrated objectively anywhere, one way or the other?

It's super easy to test. Load a textured pattern and play with it and have a look at it. More classic example, look how Sony's display those patterns from factory. It's the same exactly thing as a zone correction but an extreme case.

I'm not commenting on quantifying how good it might or might not be, merely explaining how it works so folk can see why it might have a negative impact in some images. I guess it will depend to a large extent on how much of the adjustment you use, how many distinct zones are dialed in with radically different values, etc.

Out of interest, did you ever find any good real-world examples? We all know you can find a test image to expose pretty much any image processing algorithm; alternating single pixel lines has to be one of the least likely patterns to occur in nature though.

Correct me if I am wrong but all UHD movies exist at 420 as the cost/file size of 444 would be astronomical and the visual difference imperceptible.

This isn’t passing judgment. This is an actual thing going on. Yes, these units just came out and so far 3 users are reporting issues with a clicking noise. I personally don’t see this as a flaw I could live with, considering the price I’ll be paying. If I continue to see more issues with this I will cancel my pre-order and go with something else.

I ran into the same issue with JVC's new DLP 4K but besides the Clicking there was a LOUD Buzzing when E-Shift was on. Clearly heard during most content short of Bombs or screaming Dinosaurs. You could even hear it coming up the Stairwell 15' away! Tried installing two different units before giving up and switching to a x790r.

I strongly agree with you...and with a NX9 going up in the air on Friday, I'm hoping I'll get a pass on that issue. If not, the individual concerned will not tolerate such since that pricey big girl will almost be directly over the seating (just ahead actually).

If you’ve already set up Spyder 5 with HCFR then it’s just a matter of projecting a white pattern and measuring the luminance (in nits or ft-L). The link in my signature provides some more details.

I think folks should be entitled to be weary of issues, we are all spending a lot of money.

We still don’t know what the problem was that stopped production! This could be it and maybe the firmware did not fix it completely? I don’t think we will ever know because jvc did not identify the problem publicly.

I’m starting to think jvc pushed this year units out too quick, maybe they would have been better off waiting one more year.

It makes me think about waiting till fall until they release a revised edition.

If it was the iris, it should sound the same in high and low lamp and HDR/SDR. Now it may be harder to hear in high lamp, but the iris sound should not change going into high lamp. If it does, it is probably not the iris making that noise.

Yea I’m debating the same thing. I’m in no particular hurry.

Gives me pause as well. It is beginning to look a little like quality control roulette. (At the rate these are trickling out might be waiting for the NX5 until fall anyway).

The Integral does not strip HDR. You can continue using the Integral to get your UB900 (I assume you have this) to send SDR BT2020. The JVC will not do any tone mapping, just as your RS500 does not with SDR BT2020.

You can try sending HDR to the NX9 by simply changing the EDID in the Integral to Custom EDID 11. The JVC can then apply its auto-tone mapping.

Compare both to see which you prefer.

Question about zone alignment... does it cause image tearing? For example, if I had a single pixel vertical line that scrolled across the screen, would it momentarily disappear as it crosses into adjacent zones? Or would the line appear as a broken line if one zone is adjusted left and the zone below is left untouched? Or is the projector able to keep the picture continuous across the entire screen?

I suspect the projector keeps the image continuous... having several missing pixels in zone borders would surely be visible in content...

I used mine for about an hour last night. UPS delivered at 7:45, grr.

I heard no clicking noise whatsoever on default HLG and high lamp mode.

I did notice that my old Peerless mount I have used on my RS46 and RS600, was not up to the task of holding the beast though. When the fan kicked on HDR mode the picture actually began to move back and forth a couple of inches or so. Good thing I have the Chief to put in tonight.

I was thoroughly impressed with the picture in HDR, watching Dunkirk and the helicopter scene in Mission Impossible, even with default tone mapping I found the picture to be better than using MADVR and my RS600. Not only was there more detail to be made out, blacks did not appear to be crushed in some spots that previously had black crush.

I have less and less SDR content but it will be interesting to see how that looks. I feel that will be the the trade off coming from the RS600. Give up a bit on SDR and gain it back on HDR.

Pixels won’t “disappear” as the the adjustment shifts red and blue to align with green which remains untouched. Not only that, there should be no major differences in the adjustments between adjacent zones.

But I also recall reading the opposite, that despite many recommending not using it, there is really no harm with zone adjustment.

Has this been demonstrated objectively anywhere, one way or the other?

Hi Yoxxy,
Just curious, which Peerless mount do you have. I was considering the PRG_UNV, but am worried now it may not be up to the task
