8) Calman is NOT the 'only' calibration software that works.
In fact, it is not regarded as the best, as many independent tests have proven that better results are attained via ColourSpace and LightSpace.
(A selection of independent feedback can be found here: https://www.lightillusion.com/forums/index.php?action=vthread&forum=13&topic=374
- as well as searching the likes of AVSforum - https://www.avsforum.com/threads/colourspace-cms-next-generation-calibration-thread.3049142/page-23#post-59708598
And for a lot of the described workflows, Calman Studio is needed, which is very expensive. Plus, all Calman versions have yearly maintenance fees – with the 'Home' versions having to be re-purchased every year in full.
(But, what do you expect from an Advertorial that is promoting sales bollox..?)
9) C6 Probe
The C6 probe is just an X-Rite OEM probe in drag, and far more expensive.
There is nothing special about the C6 probe, and even the supplied 'certification certificate' is inaccurate, as it is not NIST compliant.
(And it is just a certification, not a calibration certificate, performed with an expired meter, as shown here: https://www.avsforum.com/threads/c6-hdr2000-colorimeter-from-spectracal.2896137/page-7#post-60124571
Go with the standard X-Rite OEM i1D3, or even the i1D3 Plus, as both are identical, and a lot cheaper.
Additionally, LightSpace/ColourSpace has an EDR for WOLEDs that will work with any X-Rite i1D3 probe, and is not restricted as with the C6 options.
10) Calman and LG connection.
Rather than using Calman for the display connection, use the Free DeviceControl.
(To work with LG TVs DeviceControl is free to ColourSpace users.)
While Wifi can be used with LG Tvs, we do not not recommended its use for calibration.
There are far too many issues with interrupts, packet failures, and more, that may be missed during calibration, but will cause errors and artefacts in the final calibration.
12) Pattern generator.
While the CX does have an internal TPG (but older models do not), it has been proven to not be bit-accurate, and randomly flashes inaccurate colours, mainly magenta.
It is far better to use an external TPG so that the whole signal path is profiled. Profiling the whole signal path really is recommended.
Davinci can be used, or the Free PGenerator: https://www.lightillusion.com/pgenerator.html
- with a HD Fury as needed for HDR metadata.
13) TPC and GSR
Disabling TPC and GSR will not totally stop ABL type issues, so be aware...
(TPC is for static images as well.)
The LG will draw the same current even without disabling TCP/GSR, just it will not 'dim' the picture with paused frames
14) Connecting to the LG TV.
As mentioned before, the Free DeviceControl (for ColourSpace users) is better for LG management.
15) Calman Requirements
There are also a number of inaccuracies with the requirements for Calman use.
With some of the suggested approaches, an Ultralink card is needed, and that cannot be used with Calman LG Home, and needs the very expensing Calman Studio version, as well as paying yearly maintenance fees, as mentioned previously – be aware of overall costs, as they are not as suggested.
16) HDR Settings
The HDR settings within the TV should really be set to values that match the display's capabilities, not idealised values. But, as the LG is not a mastering display this is likely to be problematic... Probably sticking to fixed values, even if they are not actually correct will minimise issues – but this has not been explained well at all. The obvious error being the use of 1000 nits, when the display cannot make that.
17) C6 Probe again...
More bollox – it is JUST an i1D3 OEM in drag, with a very high ticket price.
18) Next, Next, Next...
Yeah, very restrictive and means you do not understand when things go wrong.
But, that is a user's choice – personally a less restrictive approach always generates better end results, as independent testing has proven time and again.
(It's also obvious Dado has no real idea what he is actually doing/saying, as he has connected to the TV as an 'LCD 2019'... the probe in use changes from a C6 to the later C6 HDR2000... and the 'Post Calibration' graphs show no calibration data at all, as well as randomly showing SDR Calman screens, when talking about HDR... Just more sales Bollox slide show images, with no valid information/data...)
19) Judd Vos Offsets.
No! The Judd Vos offset is for RGB OLEDs only NOT WOLEDs!
And trying to use it will never match the Sony Dado is so keen on!
20) Autocal dE Formula
No calibration system should EVER use a dE formula for calibration...
It really is that simple.
It doesn't matter what the dE formula is, it is just wrong to use it for calibration – ever.
The use of dE is just for an assessment of calibration accuracy, after the calibration has been performed, and should never be the actual basis for calibration.
This goes a long way to helping understand why Calman often has issues with calibration accuracy...
21) Legal Range during calibration
The TV actually uses 16-255 range for SDR, so be aware of that, as if that is not used the results will not be as expected. HDR is 16-235.
22) 3D LUT
No, a Matrix is NOT a 3D LUT, as it uses just 5 patches, and no, the patch sequence is not in the slightest bit important for a matrix – you have to use the same 5 patches regardless... That really is just 'sales bollox' to suggest otherwise.
Also, with the LG no 3D LUT can be used for HDR (as the instability of the display means the required profiling just does not not work with Calman).
A 3D LUT calibration would work with ColourSpace, as it has the required capabilities to overcome the inherent instability issues...
This is proven by the FSI WOLED displays, which use the same LG glass, and can be 3D LUT calibrated with ColourSpace/LightSpace, but not with Calman.
, where it states *Note: CalMAN can only be used for SDR calibration. The same is true with ASUS Proart HDR displays, with Calman incapable of performing calibration.)
For SDR a 3D LUT can be used, but still Calman can only work acceptable/reliably with limited patch sequences (Lightning LUT), while the best SDR results are generated with ColourSpace, and large profiles sets.
(See the previous links that compare the issues with Calman calibration vs. ColourSpace/LightSpace.)
23) Tone mapping
There is no mention of Tone Mapping at all, which again shows the lack of understanding Dado actually has with regard to calibration.
For any attempt as using any display for HDR work (rather than home viewing) any tone mapping must be disabled.https://displaycalibrations.com/lg_templates_for_device_control.html
(Ted helped Portrait/Calman correct their inaccurate PQ data.)
So, after wasting another hour or more of my life, it really is just paid-for sales bollox, with a lot of inaccurate statements, and little that would expand anyone's understanding or knowledge.
After the issue we have with https://www.lightillusion.com/forums/index.php?action=vthread&forum=13&topic=352
our work, I guess it is not really a surprise...
Some links for research to further understand the reality of LG calibration, and potential issues associated with different calibration approaches.
The LG TVs that can be 'calibrated' are: 2020 BX/CX/GX/WX/ZX, 2019 B9/C9/E9/W9/Z9/R9, and 2018 B8/C8/E8/G8/W8, and 2017 B7/C7/E7/G7/W7 models with Technicolor 'Studio' Firmware.https://www.lightillusion.com/lg.htmlhttps://www.avsforum.com/threads/colourspace-cms-next-generation-calibration-thread.3049142/page-23#post-59708598https://www.avsforum.com/threads/2020-lg-oled-calibration-and-user-settings-no-price-talk.3113174/page-42#post-60162967https://www.avsforum.com/threads/dedicated-raspberry-pi-pgenerator-thread-set-up-configuration-updates-special-features-general-usage-tips.3167475/page-21#post-60364650https://www.avsforum.com/threads/colourspace-cms-next-generation-calibration-thread.3049142/page-48#post-60106862
