Great, thanks. And also MadTPG and MadVR were just used to generate patches for profiling frm an HTPC? (driven by LS)

Yes, exactly.

There is a new videoscale filter which has been added for LG's 2018 1D/3D LUT, to the LightSpace Beta.

Using that filter, you can use 16-235 patch generation with CR85....and videoscale each 1D and 3D LUT's with that new filter before exporting to DeviceControl LG format.

That filter called 'VideoScale Sub Black', which re-scales the 100% White from 255, to 235. Its for LG only that filter, because internal LG LUT tables are 0-255 (0-1023).

The correct TV setting (as internally designed) is to have CR100 when you will send 16-235 patterns (because internal LUT is 0-1023 with the video black '64' mapped to '0' of the LUT) so when you have CR100... the 940 expanded to 1023.

With the new filter, the 940 will stay to 940 and from 940 until 1023 it will be interpolated, when you will measure with 16-235 patterns with CR85 setting.

So there available 3 ways to calibrate these displays for video levels via LightSpace and LG Template for DeviceControl:

1) 16-235 patch generation with CR100 (no filter required) HDMI Black 'Low'

2) 16-235 patch generation with CR85 (videoblack sub black filter required) with HDMI Black 'Low'

3) 16-255 patch generation with CR85 (no filter required) HDMI Black 'Low'

I will write the documentation and post instructions for everything, for LG Template to start being available...
Ted, are all 3 of these 'ways' equivalent in terms of accuracy and precision, or is one of them a bit better than the others (higher peak brightness, lower dEs, whatever...).

I understand that for those with existing TPG setups, they need to know which option works for the patch-types they are able to generate, but for those of us that have not yet selected a TPG solution, knowing which of the above 3 options is 'best' would help understanding what to aim for as far as a TPG solution...

All these options are available for users with various pattern generations, so they choose according to their patch generation levels they will use.

For Example if you have Amazon FireStick with LightSpace Connect, you can do RGB-Video 16-235 patch generation only, so using CR100 you clip 'headroom', with CR85 you allow 'headroom'

For PGenerator (Raspberry Pi based) users, they can do RGB-Video 16-235 or RGB-Video Extended 16-255.

If you have DVDO/Murideo/Accupel, you can do RGB-Video / RGB-Video Extended or YCbCr 4:4:4/4:2:2 (so 16-235).

If you are using MadVR, you can do RGB 16-235 patch generation.

Understand, thanks.

And the final results using any of the above options would be identical, right?

As far as I know and understand, it’s better to profile at CR85, because profiling at CR100 and then going back to CR85 when finished will give some gamma issue.

After further testing, restoring back CR85 after profiling using CR100 is not required, since its been added to LightSpace the VideoScale Sub Black Filter, so you always keep the same CR setting after profiling also.

Its up to the user if he will profile with CR100 or CR85.

LG OLED's 3D LUT Profiling using LightSpace Thread

I also find the sweet spot with my actual setup. Until my new gear arrives I can enjoy some movies now. We did a bunch of tests with a lot of different settings so everyone who didn't want to waste some time can use my settings as a guideline such as the one from sat4all.

LG 65C8:
- 04.10.31 firmware
- SM ASBL deactivated
- OLED Light 27 ~ 100 nits
- Brightness 50
- Contrast 85

Setup:
- iD3 Rev.B
- DVDO @ 16-235 4:2:2 and 12 bit
- Lightspace 10.0.0.2934
- DC with LG template
- 1D LUT: gray large + Gray large for Aug data
- 3D LUT: 17^3 Finseq + 10^3 Finseq Pre Roll
without Aug data (Aug Data for 3D LUT causes banding)

I used also the new Sub Black Filter for all my converting in LS.
















I want to thank especially Ted for all his efforts and help to make this results possible

I reprofiled my C8 with a K-10 A which I profiled against an i1Pro2. It was the first time with my OLED that I was able to overcome the red luminance issue during the FCCM creation. As you can see on the left bottom corner on my Chromasurf Screenshot it's in the NIST tolerance.



The 21^3 profile with pre roll just rushed through and only took 2h 40 and honestly I never want to go back to a id3



The drift improved also from the speed of the K-10A

So did you lift 2p low to reduce the black chrusch the LG 04.10.31 fw gives,i had to choose that way,since you now have a klein you can have a look at the darker sides of oleds
