Now this is interesting:

"There is also an integrated test pattern generator inside of the LG OLED models. If you’re calibrating with CalMAN, it can create its own test patterns so you don’t need to connect anything over HDMI and it can do it with full 10-bit triplets. You’ll still need software and a meter, but it makes the process that much easier and more reliable."

I don't suppose this is something we'll see being implemented on the older 2018 models?

Unfortunately the internal pattern generator is a 2019 TV feature only. It does however support SDR, HDR, and Dolby Vision Calibration.

Awesome feature, hopefully, this is something that will become standard across all displays.

I was wondering about highlights that are associated with color saturation, something I didn't know I was missing, until I actually did a color calibration. At the bottom of the article it is mentioned, but only concerning white boost being disabled. Ultimately, I prefer detail over brightness or a balanced approach.

The same functionality as the 2018 TVs. However now you can reset a CalMAN calibrated picture mode back to factory, without having to factory reset the whole TV.

Is this something that will be coming to the 2018 models? Resetting a CalMAN calibrated picture mode without needing to do a factory reset?

Also for the 2019 is it possible to have a unique custom tone mapping per picture memory as well as per input?

Is this TPG solution inside the TV (DDC) or is it a kind of client3 client?
Will it be usable only with CalMAN or also by anyone who knows how to control/activate it?

1. Unfortunately it’s only a LG 2019 TV feature


2. Each HDR picture mode can have three custom tone maps. The TV will interpolate in between the three that you set up. Say you set up tone maps for 1000, 4000 and 10,000 nits content, If you play 6000 nit content the TV will interpolate between the 4000 and 10,000.

The pattern generator is a part of the LG Alpha9 Gen2, and Alpha 7 Gen 2 chips in the 2019 TVs.

Yes, it is good enough. But, it will be even better if you can borrow/rent or buy an i1 Pro 2 to profile it on your screen. Then it will be far more accurate.

The main benefit is that once profiled, your meter will be far more accurate for that screen. You could do a quick search on Spectro vs Colorimeter and you will get good information.

I don't have an Oled TV. Someone with that model could chime in whether it is good or if there is room for improvement. Compared to what I have that looks great!

Like many others you used the wrong EDR for the meter. The OLED one is for RGB OLED only and not for WOLED like the one you tried to calibrate. You should definitely repeat with RAW XYZ.
L30Z3N and Rolls-Royce like this.

I did the hdr calibration again with my i1display pro profiled by the spectro i1pro 2 bought almost new on ebay.

I have a few question :

Is the white color accurate with i1pro2revb?

Do you calibrate hdr on D65 white target or i see some pro use a custom point? What's best?
I also think technicolor mode dont use d65.

Any tips to set up the custom tonemapping properly?
After calibration on hdr cinema mode i have a peak luminance of 765 nit.

I read that after upload of the custom tone mapping you should have tone mapping turn off is that correct?
I found the hdr image rather dull without tone mapping on.

Cheers

It’s 70% of peak luminance of the panel for the 1000 nit content metadata.

Most studios that I work with are setting it to 50% to better match the HDR mastering display (mostly Sony X300) (this is with dynamic tone mapping turned off.)

Thanks, that is what I assumed.

What I find interesting, is I currently have a 77 A9G and 77 C9 in the house and I calibrated HDR with the latest RC1 candidate of R3 and the latest LG firmware from this month and I find that the peak brightness was around 680-687 so I set the value in Calman to 675 for the panel peak. I have run the Sony Calman as well using PGenerator . I like to use the video below for some simple testing and if you look at the section 1:45 with the white glass figurine and look at the section I enclosed a SDR screen shot of and the section I have circled the LG tends to still clip that section, but the overall APL is good which the Sony seems to lower the overall APL a bit and maintain more detail in that one leaflet.The LG panel now has over 100 hours on it and I plan on doing another calibration and may set the panel peak brightness to say 650-660 to see of maybe it holds onto more details at the high end.

I am liking the overall DV and HDR presentation of the LG better an currently planning on have BB pick up the Sony, but I have another 2 weeks before they can come get it so I have been doing some comparisons. And while the Sony does handle some more extreme motion challenges better it is not frequent enough for me to keep it.

I would have thought this thread would have got more traction than it has, as it would be nice to share different settings, I'm a bit of a newb to this myself and would have thought many would have posted different settings at this stage. Pity
