Hi,

Z9D/A1/AF8, all these TV's have 10-Point RGB Balance controls.

Z9F/AF, these two TVs are coming with 10-Point RGB balance controls (and full CMS), but you can unlock two additional picture modes; Custom Pro 1/2; and 20-Point RGB balance controls when you will just install the CalMAN Bravia App. (It will not require to own CalMAN license for that)

After the installation of CalMAN Bravia App, these additional calibration options will be available to normal OSD menu for all users.

Then, you can use ChromaPure or any other calibration software you like to perform manual-cal using normal OSD menu 20-Point RGB balance controls.

I'm almost positive my understanding is flawed.
When you have available both 2-Point and 10/20-Point RGB Balance controls, its better to start the 2-Point RGB balance calibration first, using 100% White and 30% (or 20%...need some testing to see which one will handle better the whole grayscale), after a lot of back/forth, when the measurements will be stable (because when you adjust 1-point, it will required re-adjustment the other point also)...then you will move to 10/20-Point RGB balance.

When you perform 100% White calibration, use the RGB gains controls only to fix RGB balance errors (not use them to handle peak output), keep one color channel at zero (or untouched position....the one channel you will found that has less luminance compared the other 2 color channels...so reduce values from the other 2 color channels to calibrate the RGB balance); while using Brightness (which working as back-light settings to Sony's) you can handle your peak output.

There display which are suffering with some issues related with a un-align of available calibration controls (10-Point RGB Balance) to the working effecting range of the signal, for example when you display a 50% Gray patch and you dial 50% Gray RGB balance, internally to the display its not changing the 50% of Gray but another level...for example 42% or 56% etc...just for example.)

This makes the calibration more difficult and you will always introduce anomalies when you will finish a 10-Point RGB balance and you display a Grayscale Ramp, there will be visible issues there with strange color-shades.

There specific values (to each display) of contrast/black level controls which are align better the calibration controls and it will be helpful to measure with 21-Point Grayscale patterns when you calibrate using the available 10-Point controls you have. Doing this will be able to spot better any anomaly and prevent issues.

Its also a better idea to take full grayscale sweep and not do real-time adjustments, to be able to spot easier your adjustments how they affect the grayscale performance....so measure fully grayscale (with menu OSD off)....then look your RGB Balance / Gamma charts....open OSD...apply the adjustments you believe they will help...then close OSD and remeasure grayscale again.

To some displays, the RGB balance controls design in such way where they will align better to exact 10-p luminance levels when you will have contrast/brightness to default positions, to other models it will align better when you will have contrast at max position, this is something you need to test. That un-alignment can interact and shift each RGB balance controls to higher or lower affecting luminance range.

Hey Guys I'm a novice to calibration and have a copy of Chromapure 3 and have used an older spyder 5 meter to calibrate a cheap tv and an older 720p projector grayscale and gamma for SDR to some success. I have just purchased a new Vizio PQ65 and new i1 display pro and had a few questions before I dive into attempting to calibrate it. The proper steps if I'm correct would be to properly set brightness and contrast, move on to 11 point grayscale, gamma then finally color management? I think I have a pretty good understanding of the needed work flow for SDR (will tackle HDR after picking up some patterns and reading more). My only real pressing question is for a new quantum dot FALD set I'm not sure what the proper pattern size is appropriate whether it being standard windows, APL windows or small windows and at what color intensity? Should I be using standard windows with the default 75% color intensity? Thanks all

This is correct, except you'll probably have to go back-and-forth at least one round with grayscale and gamma. When you change the gamma that usually throws the grayscale off some, so will have to readjust that. The calibration steps for HDR are essentially the same, except you need to use 50% Color Intensity and 50% saturation test patterns in Color Management. Be aware that you will be able to calibrate grayscale to follow the PQ curve up to 60-70%, depending on the display's light output. Beyond that, allow the display to tone map.

When calibrating an LCD/LED for HDR you must use windows. I'd just use standard 10% windows. For SDR calibration on this type of display test pattern size is not really critical, but staying with 10% windows would be the simplest. BTW, I wouldn't try to measure black level on a FALD set unless you first turn FALD off. Otherwise, you are likely to measure zero for black.

Hi guys. I have an old license only for CP version 2.5.5. Does someone maybe have a download link? I emailed CP but I need to calibrate today.

Might be too late but you can try this link.

http://www.chromapure.com/distribute...chromapure.zip

It points to a version from 2015 so I think it is 2.5.

Edited to add Oh well, someone beat me to it.

just ran through my first calibration as a learning run. i finally got the disc to work in my Panasonic ub900. i had to burn the iso to an actual BD-R disc before it would work. DVD-+R and RW's didn't run. Anyways, I must not be doing something right because my Gamma flatlines at 0 and no matter what i do i can't get it to register. I ran through the entire calibration and it seems everything worked except the Gamma. So i don't know if the calibration even is correct. in the color gamut, with the exception of green and magenta, all colors are below 1.5 delta. green is ~1/9 and the magenta is ~2.0. i'm going to give it another try tomorrow but i need to know if there's a setting I'm not adjusting correctly for the Gamma to register. I have the Epson 5040, Pan UB900 and i1Display Pro.

Before you ask...i don't have any pics and didn't save anything. I will tomorrow and will post them. newbie mistake, sorry.

Post a pre-calibration and a post-calibration report, to have better idea of your calibration.

Calibration Report

I attached the pre/post report. I think I newbied my way through it but let me know if you see something really wrong. There were some issues with trying to get red and magenta close to 0 but I did my best. This was measured off the screen and next weekend I'm going to try off the lens to see if the results are better. I'm using the 5040ub shooting on a silver ticket with 1.1 gain in a totally dark room. Thanks for any suggestions or advise.

Yes, i see the same too for my LG OLED C7.

High dE in 5IRE and 10IRE. And the gamma / RGB is very unstable at 5IRE and 10IRE no matter what i try.

Should i just leave the 5IRE and 10IRE RGB levels at its defaults and just tune the GAMMA to 100%?

Once you have these points, if you go to our support page you can download a file that you subsequently import into Raw Data to create a custom grayscale list. Use this to perform the grayscale calibration.

which part of the HDR workflow should this be done? because there is precalibration and post calibration greyscale measurements, and will they need the "new values" from LG.

So, to elaborate on the earlier post as it was late at night and I just really wanted to get the file uploaded. I was having an issue with the Gamma not registering off 0 not matter what changes I made. I ended up uninstalling the software and reinstalling and it started working correctly. Not sure if there’s a glitch or not but either way I was able to get readings.

So, my base measurement was in Natural Mode default settings as this was the closest to hitting all the targets for where I should be. Thought was, that I would have to make less adjustments to get it as close to where it should be.

I own the 5040UB and some of the issues I find with the calibration for Rec. 709 Gamut SDR settings is that on my projector it is very difficult to get red, yellow and magenta to cooperate when adjusting the Hue, Saturation and Brightness settings. Must have spent 30 minutes or more on Red alone trying to get it close to reference but was unsuccessful. The same with yellow and magenta. My gamma control settings on my projector are, IMO, odd to get gamma to be spot on, or really close to being spot on. I might be overthinking the gamma, if I’m getting the readings I’m getting, I should be happy. All my settings are below.
