Official JVC - 20LTD - RS640 (x990/x9900) - RS540 (X790/x7900) - Owners Thread

Calibration suggestions for rs640, x990, x9900, rs540, x790, x7900


Suggestions for SDR Sources:

Picture Mode : Natural
Color Profile : Standard , Video or Cinema 1 (709)
Color Temp = 6500K
Gamma = Normal (alts = Gamma A, B, C or Custom 2.4, 2.3, 2.2)
Master Contrast = 0
Master Brightness = 0
Master Color = 0
Master Tint = 0
MPC Settings
4K e-shift = ON
Graphic Mode = 4K
Enhance = 0-3 (movies with heavy grain) 4 (movies little or no apparent grain)
Smoothing = 0
NR = 0
Blur Reduction Settings
[SIZE="2"]Low Latency = OFF
Clear Motion Drive = LOW
Motion Enhance = OFF
Advanced Menu
Clear Black = LOW (try HIGH for nice RC type detail boost in darker parts of the image)
Lamp Power = LOW
Lens Aperture = Manual -5 to -9 (0 if you like max lumen output)
(for max brightness and best dynamic contrast set Lens Aperture = 0 and AUTO 2)



Suggestions for HDR Sources


Primary x990 Settings

Picture Mode = HDR
Color Profile = BT.2020
Color Temp = HDR
Master Contrast = 0
Master Brightness = 0
Master Color = 0
Master Tint = 0

x990 ST2084 Settings

1 - My Favorite
Gamma - ST.2084
Picture Tone = 11
Dark Level = 3
Bright Level = -7

2 - Very close to ChadB #2 Bright Curve
Gamma - ST.2084
Picture Tone =7
Dark Level = 3
Bright Level = -7

MPC Settings
4K e-shift = ON
Graphic Mode = 4K
Enhance = 0-3 (movies with heavy grain) 4 (movies little or no apparent grain)
Smoothing = 0
NR = 0
Blur Reduction Settings
[SIZE="2"]Low Latency = OFF
Clear Motion Drive = LOW
Motion Enhance = OFF
Advanced Menu
Clear Black = LOW (try HIGH for nice RC type detail boost in darker parts of the image)
Lamp Power = LOW
Lens Aperture = Manual 0




UB820 - SDR2020 -> X990


x990 Settings:

Picture Mode = User 5
Color Profile = BT2020
Color Temp = HDR (6500k)
Gamma - Custom 3 (2.4 Gamma - alts 2.3, 2.2 to increase shadow detail) (also check out the B gamma)
Master Contrast = +2
Master Brightness = +2
Master Color (saturation) = 0
Master Tint = 0

820 settings

HDR Mode = SDR/2020
Optimizer =ON
Luminance Slider = 0 is good but you can push to +3 or +4 (as you push beyond +4, you might notice some artifacts, such as loss of detail in highlights, in surfaces or faces which can look over exposed)
Brightness = +1
White Tone Level = 0
Black Tone Level = +3


Here are recommendations from Kris Deering

http://forum.blu-ray.com/showthread....5#post15374135


UB820 - HDR2020 ->X990

Note: Based on owner feedback on a LS10500 projector calibrated by ChadB, he suggested trying 820 in HDR mode with the optimizer ON. This was a successful test using the 820 in HDR/BT2020 mode with the 820 optimizer ON, and with my favorite x990 HDR ST2084 calibration.

x990
Picture Mode = HDR
Color Profile = BT.2020
Color Temp = HDR

x990 Gamma: ST2084 Settings

1
Gamma - ST.2084
Picture Tone = +11
Dark Level = 3
Bright Level = -7

2 (Push the 820 dynamic slider a little more. These are settings close to ChadB #2 bright curve.)
Gamma -ST.2084
Picture Tone = +7
Dark Level = +3
Bright Level = -7

Master Contrast = 0
Master Brightness = 0
Color = 0
Tint = 0

820 settings
HDR Mode =HDR/2020
Optimizer =ON
Luminance Slider = +4 (push a little more 6, 7, 8 with #2 st2084 settings)
Brightness = +1
White Tone Level = 0
Black Tone Level = +3



OPPO 203


Oppo 203 Settings:

HDR off BT709
(HDR off BT2020 currently has issues with color gamut and color saturation. Use HDR off BT709 instead.)

Mode 3 & 300-600 on the luminance slider (higher number reduces highlight crush)


x990 Settings:

Picture Mode = User 5
Color Profile = HDR (using BT.2020 provides no benefit until OPPO fixes the bt2020 issue.)
Color Temp = HDR (6500k)
Gamma - Custom 3 (2.4 Gamma - alts 2.3, 2.2 to gradually increase shadow detail as desired)
Master Contrast = 0
Master Brightness = 0
Color (saturation) = 0
Tint = 0


Give these settings a test drive. Feel free to report your feedback.

Grats!

I hope to have my X9900 in a couple weeks and will be doing an in depth shootout between it and my X9500.

EDIT - I have my unit now, so here are my thoughts all collated... My unit is not a good sample, I will be replacing it and will update my thoughts on that unit, most of this was shot from the center of the screen though so for the most part its still going to be a very relevanty comparison, since both my lenses are sharp in the very center. Its the outer edges I have issues with with regards to this lens.

----

I am disappointed overall, and its mainly a gut feeling though, a few things stand out, but it seems to gain a couple steps in one area we give up one or two steps in another area.. I am torn on weather I will keep this projector.

There, got that out of the way.

Here is what my shelf looks like right now...




Eshift buzz is definitely reduced since when I first turned it on, it sounded dead set like an electric razor at first, by the end of the night, 4 hours later it was about the same volume as my old unit, unless you put your ear right up to the 9900 and then the frequency was a bit different. No big deal here.

The 5 seconds improve sync time in Low Lag mode is very nice. 11.8s in low lag mode ON, 16.8s Low Lag mode off for a 4k Desktop to appear.

Turns out this lens is not as sharp as my 9500, once I studied all the corners of the lens it was clear it wasn't quite as sharp. My 9500 lens is pretty much pin sharp in all the corners, this 9900 lens appeared to be, but when I had both projectors stacked, they were both super sharp in the center, but the 9900 slightly less so, and was a couple clicks less sharp on the corners and this could not exactly be brought in line with the sharpness of the center. Both of these lenses though are still far out sharper than my X7000 lens ever was, so I would still say both these lenses are excellent and would quality for hand selection for the 9XXX series projectors, its just that my old one is better than the other.

However because the left side has perfect convergence, the pixel delineation appears to be stronger, however the focus grid is sharper on the X9500 in person, no doubt about it..

X9900



X9500



The chromatic aberration on the right side of the lens I have come to decide is unacceptable. I think this will be the basis of at least exchanging this unit to try another sample. While the 2/3rds of the left hand side are perfect, I would actually prefer if the panel alignment was out, that it be out by a consistent amount across the whole screen, my last two JVC's were both exactly 1 pixel blur out vertically, which is easy fix, this would require zone alignment and I am not doing that with an MSRP $10k projector.

EShift 5 with text is better than EShift 4, but in real data in video, I am not sure it can be seen at all.

My X9900 is DIMMER than my X9500 is right now at 700 hours. I'll let that sink in for a moment.

I have to run the X9900 on iris -9 and contrast -2 to brightness match the X9500 currently at iris -10 contrast -1. This is a shame, because my X9500 was at least 10% brighter than this when it was new and has dimmed itself since new. So the 9900 starting out where it is, its not looking good here.

There is some ugly super warm colour temp cast over just the menu screen, the X9500 menu screen looks like a correct calibrated almost 18% grey menu, I don't know how else to say that. I did calibrate both grey-scales on the projectors, there still seems to be a slight colour difference on screen however despite very quick cal, the menu doesn't seem to be affected by calibration at all, so that ugly red bias grey menu seems there to stay...

HDMI SYNC TIMES:

When Low Latency mode is on, my projector was syncing in 11.8 seconds for a 4k desktop image to appear, and 16.8 seconds when Low Latency mode is off. Thats also a repeatable 5 seconds quicker than the 9500 was generally. All modes seem to be between 2-3 seconds quicker syncing vs the 9500 when low latency mode is off.


LOW LATENCY MODE: This seems like it needs to be left ON at all times, at least on my unit, its sharper with it, there is some effed up blur ghosting artefact with Low Latency off, yes you read that right, Low Latency needs to be on for sharpest image. Its totally odd but the pics don't lie.


Perhaps my unit is misbehaving? It did come at default switched to On OOTB. EDIT - This has actually be corroborated by other owners, this may be a bug, but for best quality Low Latency must be off, oddly, cycling CMD on then off again removed the ghosting... but how long does that stick for? Perhaps on next power up the ghosting will be back, best to leave it ON.

ESHIFT 5 DOES NOT HAVE LESS MOSQUITO NOISE THAN ESHIFT 4. It just doesn't. The fine buzzing noise with your face to the screen is identical on both models. Sorry to see this, it was one of the things I was hoping to see improved, for a calmer image, but no.

Windows Desktop at 4k/ Still not native on either machine but no doubt the 9900 is getting closer to where it should be.

Rollover

http://screenshotcomparison.com/comparison/121495


Now for this, lets look at Eshift 5 vs 4. At first your eyes may be drawn to the vertical lines being far sharper with actual gaps between then on eshift 4 and you would be right, but look at the letters and words... eshift 5 kills it with high density 4k text. But it seems to give up something all the same while doing it... which is a lesser evil? I really don't know, I am truly torn here...

I have begun the process of RMAing the projector, hopefully the next sample is better, if its lackluster again, I will either try get a refund or sell it on, if the lens is excellent and convergence is at least consistent, meaning if it required adjustment I can do the whole screen at once, not only one side, then I will keep it.

I did spend a lot of time calibrating, and Autocaling the new unit today and kind of general trouble shooting, I didn't touch the calibration on the old unit, there was a tiny bit of colour shift, but I have slightly kicked the colour in Lightroom around a tiny bit to make these comparisons closer.

Good news is Autocal works great! Arve tool works too, just need to hit ignore a couple times on some errors but works.

Oh the Low Latency shadow wierdness bug for me seems to have gone away, as far as I can see now both Low Latency on and off look the same.

OK pics...

Here is one you can definitely see more fine detail in, again this is text only, but hey its real content as it were!

BT2020 Mode. This is covering pretty much the entire P3 gamut. HDR mode without the filter for added brightness at the cost of coverage...



----

OK here are pics of my lackluster lens and convergence! Yay!!

I literally dont even have to tell you guys which is which!

Left side of screen:

X9500



X9900



Right side of screen:

X9500



X9900




Left side of screen, both projectors at the same time.



Convergence, X9900:






What happens when I correct the convergence with zone alignment... This is a single 1080p pixel horizontal line pattern, gee this artefact looks SUPER familiar.

X9900




X9500 with normal panel alignment:



Obviously the 9900 can show that screen as clear grey too, but if I want panel alignment to be correct, I get artefacts, yay!

Oh and here is real content, top corner of screen:

Can you add the 20LTD to the title as well? ..and perhaps just like in the past the 440 should have it's own thread.

Actually yeah the 440/590/5900 needs its own thread. It does not share a whole host of features with the higher models.

No P3 filter, no dual iris, no lens cover, no THX etc... significantly different contrast levels etc

Can't wait to see how eshift 5 compares, according to JVC it seems they have pretty much perfected the tech and also fixed the bugs and added the missing features to this refresh. Shame I have to wait another couple of months for my LTD.

Nice! I guess you will try and get some hours on the LTD before shipping it up to Javs.

Curious to see at what brightness the max contrast is achieved on the X9900 vs the LTD. Wondering if the LTD's irises are shut down that much more. Javs is sure to uncover the secrets.

Look forward to his findings.

I think it's due to the panels otherwise if it doesn't reach deeper at the same iris settings it wouldn't be much of an advantage?

If it is the light engine(less irises) panels/light path components, then there is a possibility this level of performance will filter down to the X9900 down the track.

The speculative little devil in me says, the easiest way to meet this LTD spec is to reduce the aperture a bit more, although at a lower light output.

None of us will experience max contrast unless we are at the longest throw, with the irises clamped down, projecting on to 90" screens.

Do 200.

Droop will be hitting hard by then. I rather wait for the best time, get your droop totally sorted when you send it, not when its going to keep slipping for another 200 hours... Which is may do so anyway.

I think my droop has now stopped on my JVC at 600hrs. which is good... for the next owner lol.

No but if you look at the 7900 vs 9900 or the 7500 vs 9500, the contrast is not just more at the low end, it begins right from wide open iris.

The 7500 vs 9500 can/does have as much as 10/20,000:1 more on/off wide open (sample variance) and up to 40/60k sometimes more iris closed... the benefits are felt all the way through the range.

At my light output I use now, at completely minimum throw, I used to get a measely 55k:1 at 15fl on my X7000. My 9500 in the same exact spot is hitting about 85k:1 in the same 15fl... Sure I probably had a 'weak' 7000, but it goes to show the premium you pay for the best is certainly real.

Well I hope you are wrong BTW that is one of the reasons why I am building a complete new cinema building to suit the best PJ throw distance/location and get the best out of my equipment etc..
We shall see, it's only a shame though that we have to wait much longer for this beast to arrive, I believe that is due to a separate production run which might be a good thing!

Yeah that's about correct my droop settled at 700 hours the only issue is I can't autocal it as even JVC have no idea what issue is, annoying.

My x790 should be here in a couple of days but I haven't decided on a screen size. What is the minimum ftL you guys would consider optimum for HDR? If I go with a 9' wide matte white 1.0 gain screen, based on the x7500's calibrated measurements, I would be getting about 23 ftL (78 nits) with the projector on low. That's usually how I like to watch SDR at, so I'm not sure if that would be ok for HDR.

It will be in a light controlled room, with velvet on walls.

Thanks,
Mike

It Arrived!

Ok, funny that I pre-ordered last month but was expecting it much later. What a nice surprise!
Anyway, I'm hoping to post my first impressions of my X990 tonight.

More than any projector can do on a reasonable screen size. But frankly I think the talk of "minimum nits" and all is overblown, or maybe I should say, it's made to sound more strict than it really is. Just try to get as much light as possible and then calibrate as best as possible.

If you need all the light just to be happy with SDR, you're going to have a tough time with HDR.

Quick newbie question guys, sorry about this...

What exactly is the difference between the RSx40 series and the Xx90 series? I know they are sold through different channels, and I believe only the RSx40 series has the gold lens ring, but is there anything different when it comes to warranty? The internals of the machines?

Do people just buy whichever one they can get their hands on?

Thanks!
