The x770 is the same as the RS520.
I can only speak about my own experience; no one else has reported the same issue, although no one has confirmed they don’t have the issue either.
If yours behaves the same way, you would see the improved gamma right after calibration, but it will revert back if you switch modes or turn off the projector, even if you save the results.

Gotcha. Maybe I am missing it but I have run gamma and gamma/colour a few times and it seems to have “stuck”. I guess the way to test is to run it for SDR and HDR and then switch to my user mode and then run it again to see the baseline (blue line I think)

At the end of autocal you would normally see a blue line higher than the white line, which indicates that the gamma droop has been corrected by autocal. However, if you run it again immediately, you should not see the blue line as it would now be hidden by the white.

For HDR I would see the blue line every time.

A more conclusive test is to measure Normal gamma using the BT.2020 profile, after autocal. You should see a flat 2.2 gamma, but I don’t.

Yeah but for every non HDR picture mode or color profile there is just one gamma baseline that is calibrated? If that is true I am confused why Manni states that you need to perform a gamma+color calibration if the lamp mode or filter settings change. If there is only one non HDR gamma baseline then wouldn't only a single gamma calibaration be required if the projector couldn't store a different gamma calibaration for each lamp/filter setting you use?

There is one baseline gamma for each lamp/filter/CMD combination, meaning that for the same combination, calibrating Normal will correct 2.2, 2.3, 2.4 etc, as they’re all mathematically derived from Normal.
BTW, I believe CMD High/Low share the same calibration, which is different for CMD Off.

Ok. Well I can confirm I have ran it twice one right after the first time for both SDR and HDR and the blue line was under the white. I know that worked for me. However I have not gone out of autocal and changed user setting and watched for a bit and redone autocal.

On mine if you switch from HDR to User and back, the calibration would be gone.

Cool, that makes sense. I read many posts back that there was one baseline gamma that all gamma curves we're derived, that was confusing me from what I understood from reading this thread. If there is a separate gamma baseline for each cmd/lamp/filter combination then all makes sense again. Thanks for the help.

Ive got the X5900 ( I think it x590r ) 2018 software version 10 have any of these gamma and CMS issues been fixed ?

This is not really how to "create your own curves" which Arve's Tool is also able to do. I would love if someone could point me in the direction of somewhat "simple" Arve's Tool instructions from start to finish...maybe using Jav's as the start but going in further than just bbo and tweaking it to my specific setup. Anyone?

Also, has anyone used Spyder 5 with HFCR to do a) luminance nits testing and b) color calibration? I would love to hear from someone that has done this with those specific tools so I can continue to tweak this 5% left in calibration!!!

Creating a basic custom curve using Arve’s Tool

Creating a basic curve is fairly easy using Arve's Tool. Essentially, to customize it all you need to know is the peak nits you're getting on your screen when in the HDR mode. In Arve's Tool this is called “bm” (maximum brightness). You can create a curve and play with the different parameters without connecting to the projector, until you're ready to upload the curve.

Assuming you're already set up to upload Jav's curves, here's what you need to do to create your own custom curve:
  • Double-click on Menu.py to start the tool
  • Type "lp" to load one of the presets.
  • Select "3" (hdr pq 1200)
  • Type "ga" to adjust the curve
  • Type "p" to plot the default curve
  • Arrange the command line window and the plot window such that you can see both side-by-side. The plot gets updated as you change the different parameters.
  • Type "bw 25" to set reference white brightness to 25
  • Type "bm" followed by your peak nits; e.g., "bm 120"
You're done with the basic curve!

Next you can either upload it to the projector with "Pw", or save it with "s filename". If saved, you can later load it with "lf" just like you've been loading Jav's curves.

If you prefer the picture brighter or dimmer, simply adjust the bw value up or down accordingly. In most cases it should be in the 20-25 range.

Alternatively, you can also use the projector’s Contrast control to set the overall brightess interactively; see the following guide by lovingdvd:
https://www.avsforum.com/forum/24-di...l#post51467921

Most of the other parameters are for fine-tuning the highlight roll-off. They have a much bigger effect on 4000-nit curves than on 1200-nit curves.

You can also "design" your curve using HCFR. The main advantage is that HCFR includes the black compensation feature of BT.2390. I've developed an Excel Macro that will produce a jgd gamma curve from the HCFR data file. Note that the jgd files are used with the JVC AutoCal software, not Arve's tool.

Using the Spyder5 is no different than using any other meter in HCFR, other than having to load the driver.

In some cases it may be easier to connect the projector to the network hub instead of directly to the PC.

When I try to check the network connection in the JVC software under Setting, I get "Connect NG" (what is NG)
The IP address entered in the software is the same as I have set on the projector
When I click the Import/Export icon, I get "could not setup LAN connection"
What am I doing wrong?

NG=No Good.
Try clicking on SET again and see if the IP address changes; is so, enter the new address in autocal. Sometimes you have to power off, physically unplug the AC cord, and then reconnect.

I finally worked out how to import gamma curves (better late than never)
I watched the opening battle in Saving Private Ryan with BT.2020 as the color profile
I knew the blood shouldn't be that red because of the desaturated look of the movie
So I changed the color profile on the X5000 to Standard
Does that sound right? It looked right to me
Even though my Panasonic UB900 said that it was BT.2020
This is all new to me

Does anyone know what axis position corresponds to in the JVC color management system. I assume Hue, Saturation, and Lightness map to HSL, but not sure about axis position, or maybe I have it all wrong?

This previous post by Manni shed some light on the use of JVC axis position adjustment, or rarher, why not to use it:

I calibrated white balance and gray scale using Calman and gamma using JVC Autocal. The test patterns were calibrated with source in YUV mode and if I change the source to RGB it throws off white balance, gamma, and color. Is that normal?

This guide encompasses every step you need to load custom curves onto your projector and get rocking with 4K HDR. All of this is reversible and none of it is permanent, so no worries. A custom curve will significantly increase the quality of your HDR content and it only takes about 30 minutes to follow the instructions below for the first time.

In step 3 I link to a couple different curves on this forum to download. Feel free to choose your own if you find one, there is no harm in trying different curves, the projector has 3 slots for custom curves and you can overwrite them as many times as you want. You can also make your own but that process is a bit different. More information here. If you are fresh to 4K now is the time to replace your HDMI cables or you will probably have problems, more information here. I have links to posts in my sig for a reason, look at them.

This is the quick and dirty guide and will get you what you want, quickly:

1) This is the JVC Calibration Software you want to import premade gamma curves, you can also use it later to do color calibration if you want. Install this software on a PC connected to the same network as your projector. Do this first. Connect your projector to your network, check the IP address of your projector in the settings menu and enter it into the settings screen (the gear) on the software and click 'check' to verify connection. (The PDF in step 4 explains this in more detail if you need it)

2) Download the BT2020 color profile from here. Its under step 2. (You might already have this loaded on your projector)

3) Download and try some curves from this post (download via his Dropbox link) (Thanks Javs) or this post (Thanks Manni) or this post (Thanks Dominic). Full credit to Javs, Manni and Dominic on these curves, I did not make them, they did. (Or feel free to use any other curve you find on the forum)

4) Use these Import Procedure directions to load the BT2020 profile you downloaded in step 2.

5) Use the same process as step 4 to load the custom gamma curve, but you select 'gamma' from the pull-down menu on the import/export screen instead of 'color profile'. If you really want brightness, I'd start with Javs "Javs 1200nit V3" gamma curve inside the "Autocal Versions" folder in his dropbox link and/or Manni's "Manni-HDR10-BC1K" gamma curve in his zip folder into and/or "Gamma3_30_Adjusted" into Custom 3 from Dominic. (Or feel free to use any other curve you find on the forum and load them to whichever custom slot you choose)

3/4/5 alternate) You can also load a curve or two using the ARVE tool and JAVS curves. This process is a bit more complicated but his recent V3 curves are very good. Curves and steps here. Javs has also provided the regular curves to import in step 4 but the Arve tool method will technically yield a slightly better result if you like his curves. (I personally saw no difference between the loaded curve and this method but it is ‘technically’ bettter).

6) Okay all done on the PC for now. Go to your projector and stick in a 4K disc get it loaded up so the movie is playing.

7) Now we're going to set up your picture settings for HDR movies on your projector. Press a User Mode on the remote (I have a few different profiles set up so my User 1 is for HD, User 2 is for HDR and User 3 is for 3D). Choose and press a user mode that makes sense to you, then go into the projector Picture Adjust Menu and change the color profile to BT.2020. Change Gamma to Custom 1 (or where you loaded the custom gamma from step 5), then right below that in the gamma screen, change correction value to Import. (Very important to select Import, otherwise it won't load the profile you imported in step 5). I'd also suggest turning on High Lamp, CMD Off, Auto Iris off, Iris Manual on 0 and Clear Black Low. (Iris, CMD & Clear Black is a preference though).

8) Going forward, once you put in a 4K movie, all you need to do is choose that user mode and it will recall all the settings from step 7. Then once the movie is actually playing, you just need to hit the gamma button to change from Gamma D to Custom 1 (the projector will always default to Gamma D). You can also rename the Picture Mode from "User 1, 2 or 3" to "HDR" or something to make it easier for you.

That's it. Basically, in recap, load in the BT2020 and custom gamma profile with the software, choose a user mode on the remote and select the BT2020 and custom gamma profiles.

All this will take about 20-30 minutes the first time. Its pretty quick. You can try different gamma curves in slot 2 & 3 also and overwrite them all as you see fit. Once you get the hang of it you will only spend like 2 minutes loading a gamma profile. REMEMBER, be CERTAIN the gamma correction value is set to IMPORT on the projector, otherwise it's just gamma normal.


On one hand I'm extremely thankful that Dreamliner has produced a quick-start guide like this.


On the other: it's pretty much all Greek to me. I have not ever personally calibrated my JVC RS600 projector. Or downloaded anything on to it. It looks to me like a whole bunch of ways I could screw up my projector!


This is why I've used a local professional calibrationist to do it for me. The problem is everyone is telling me a calibrator can't do UHD properly, that it has to be all this custom-done stuff...which I don't know how to do.



For instance, step 1: Would I be downloading the software into the projector somehow? Or would I be downloading it to a computer used to calibrate the projector (e.g. laptop)? Same question for any other downloading steps. Where is it going? (See...I really haven't done this before).



I thought the JVC calibration software was a no-go as it sucked?

Every few months when I go to use the JVC autocal software, my Windows 10 PC doesn't recognize the Spyder. To resolve it I have to reinstall the Spyder software (so the driver gets reinstalled I suppose) and reboot. Then it works. Until a few months later when I go to try again, and I have to rinse and repeat. I don't calibrate it enough to really make it worth deep troubleshooting, as it's easier to just reinstall the Spyder software than to worry with it. But while I was here I was just curious if anyone else has had this issue or knows how to solve it more easily.

If your calibrator is not familiar with these quirks and tools for setting up HDR on an RS500, just pay them for doing a great SDR calibration.

Most of them use the JVC autocal software for the gamma setup because it is more fine tuned than manual adjustment, but a few calibrators can do well without it.

The other steps and software described here are for getting HDR to work as well as possible.

Alternate methods:

1. Don’t send hdr to your projector. Use something like the oppo to convert hdr to sdr.
2. Take a trip down the rabbit hole and learn how to upload someone else’s hdr curve to your projector. It won’t be as precise as an experienced calibrator could do but it can work well. You’ll need some basic computer skills and a weekend of patience. (It can be done in an hour or two but the first time out, most of us ran into problems and had to post online for help, and wait for an answer or two....)

Hi all,

I'm a bit of a newbie to the calibration world and will be looking to calibrate my JVC first time over the weekend. I have a few q's I was hoping someone could answer...

1) It's been said many times on the thread to calibrate with Gamma normal. I'm happy to do that, but I use MadVR HDR to SDR mapping which requires me to set Gamma to 2.4 for the best results. If I do that, will I still get a calibrated image or can I keep the gamma to normal after calibration as the spyder and the software has already calibrated to 2.4? Very confused with that one.

Thanks in advance
