I tried to make a Resolve 3D-LUT with a Decklink studio 4k connected through HDMI to a Panasonic OLED FZ800 tv, with a i13D probe.
I set the decklink output to Full range and accordingly to HDMI Full on the tv.
I put BT gamma on both dispCal and TV and I slightly corrected the tv luminosity to see the low pluge bars and I deselected apply vcgt. As a spectral correction I used WRGB LG OLED.
I did the 3d-LUT (after a quite perfect White balance and cd/m2) but the result does not seem that perfect, in particular on the triangle gamut edges R,G,B considering the OLED has 100% REC709 coverage.
I attach the zip results.
What I made wrong/ could do to make better? (I expected a quite linear full Rec709…)
thank you.
I have a similar problem. I’m trying to calibrate an LG Oled B7 with I1 Display probe, using Resolve as a pattern generator. Using Decklink SDI and a BM SDI to HDMI converter which has a built it LUT, generating a 33×33 cube LUT.
Been trying for quite some time but cannot get anything remotely close, the verify results are wildly off as well as visually. The monitor is already visually close without calibration but using the LUT makes it a lot worse. I am doing something majorly wrong…
Is there a step by step workflow to follow, or a checklist and what to do and what not to do. It’s just a jungle of all sorts of esoteric settings and no way really to get clued up on it.
BTW I am using the same probe to calibrate the computer system monitor, a Dell UP3216Q, with very good results, it works just fine, there isn’t anything wrong with the probe. It’s either the LUT generating, or the probe is just not working with the OLED spectral response – there are different correction matrixes for the B7 which I tried but didn’t make a difference.
@Frank10, that CCSS is broken. It is not just that that CCSS matches or does not match an WOLED TV… it’s just broken. Plot it.
The one who created that CCSS did it in the wrong way. There seems to be at least 3 versions of that file, same date, and just one it’s OK.You may try instead:

but unfortunately it is a CCSS from an OLED in rec709 gamut emulation.. it should store native backlight instead
@All, newer versions of DisplayCAL have a combo box in profiling tab to maximize difference in brightness between patches so it helps to avoid automatic brightness level in consumer OLEDs. Make sure you use it.
Another way is just to use C7 WOLED from DisplayCAL:
or E6V model. Unfortunately all of these store the same Rec709 gamut emulation with this exception:
https://colorimetercorrections.displaycal.net/hash/e141c25a997b2130c84343172be412d4/OLED%20E6V%20Colormunki%20photo%20wide%20gamut.ccss
This one seem s very close to what a WOLED native gamut spectral power distribution should like.Thank you Vincent, I tried the E6 ccss, but it’s worse, especially in the green point.
I tried also the first one you posted (JETI B7) but it seems to be similar to my result: red is over the correct point of CIE triangle and blue is a bit inside the triangle. And always about 96% Gamut coverage and 97-98% Gamut Volume.
I’ve not understood what do you mean with “Rec709 gamut emulation”: shouldn’t be correct using 709 in SDR content and rec2020 in HDR ones? So a 709 ccss shouldn’t be ok for SDR?
Have you some good 3d-lut graphic that has good coincidence points in CIE Gamut? Just to see what is the optimum to aim with these OLED LG panels…
And always about 96% Gamut coverage and 97-98% Gamut Volume.
Maybe what is wrong is Rec709 emulation inside the TV (from native WOLED gamut to Rec709, “native gamut to Rec709” calibration from factory) and what you measure is real. Your TV may actually behave in that way when you use its Rec709/sRGB modes because if an inaccurate factory calibration to those target colorspaces.

WOLED panels or LED backlight panels have a native gamut. For example last CCSS showed WOLED native gamut spectral distribution with ~9x% DCI P3 gamut.
They could have several OSD preset with smaller gamuts, they are called emulated gamuts modes (you can call it by many names, this is just one).In these emulated gamut modes each “new” R G & B emulated primary is a linear combination or 1 to 3 “native” RGB primaries.
For example if you plot that spectral power distribution data for Rec709 modes CCSS and for native gamut CCSS (last one) you can see that RED channel (emulated Rec709 channel) is a combination of the 3 RGB OLED channels in its native gamut configuration.
—————–
People “usually” profile their monitor/displays at native gamut, then build software LUT3D to “limit” that big gamut to Rec709 or P3 or whatever (portion of) colorspace you want as target. This is one way to (if possible) avoid what you experience.
What OSD modes in an WOLED TV allow you to use native/P3 gamut… IDNK, check TV manual if there is an SDR P3 mode. Profile it, then use DisplayCAL to compute LUT3D for Rec709 of whatever you want in whatever format you wish (madVR, resolve…). Then validate it (measure).Excel, Numbers, Libreoffice… save 4 rows without their indexes (1,2,3,4) in a text file. Change spaces by “,” (or “.” to “,” and ” ” to “;” in some countries). Then you have a CSV file. Open it in a spreadsheet. Add another row on top with wavelenght information (that “SPEC” numbers). Transpose, add W,R,G,B headers to the 4 columns, plot it.
Another option is to build an application to do that from CCSS… maybe it can be a nice feature to add to DisplayCAL in future versions, a “visual check” of a CCSS made by user before blindly trust in it.PS: I said red, but it’s actually green when you can “see” it in a more clean way in a plot. My mistake
PS2: Has the E6 CCSS with native gamut WRONG order in rows? Seems to be “WRBG” instead of usual order WRGB.
Anyway, you can see how green channel is a mixture or native R , G and B (with different ways).
It’s not a bad practice to plot a CCSS before using it… some users seems to fail th build them properly.Another option is to build an application to do that from CCSS… maybe it can be a nice feature to add to DisplayCAL in future versions, a “visual check” of a CCSS made by user before blindly trust in it.

specplotdoes plot CCSS spectral curves (although channel naming may not be correct).I didn’t know that functionality, thank you!
It seems that each channel plot is color encoded.Do yo know if Argyll measurement apps (for i1d3) is order sensitive about CCSS? I mean, will Argyll tools work OK if you feed them with “RGBW” ordered CCSS like in OP’s 7zip file?

This one is native gamut “WRBG” (wrong order?)
and this one is emulated Rec709 gamut (WRGB order)
As you may see, green channel is a combination of “native” primaries (and red too). This way you “emulate” Rec709 gamut.
Maybe is your TVs “Rec709” osd mode (or whatever similar OSD mode you used) what is limiting gamut in blue because of “wrong” factory calibration (wrong combination of weights in “emulated” primaries)…. so if you are concerned about Rec709 % coverage as it seems form your message, try to make a profile in a wider gamut OSD mode, then build LUT3D to limit to Rec709.

Please let me know if you need me to rephrase anything or what have you. I’m not good at putting my thoughts into words, which my opening statement kind of shows lol.
I’ve attached my most recent profile if you want to compare yours to my 2016 model (E6). I have 99.84% sRGB coverage with this profile but have had 100% with a few different settings. More about this at the end.Sorry, this might get long. 😛
Vincent, just an FYI, the CCSS file used by the OP was made by Zoyd (HCFR dev). According to others on the HCFR forum it seems to be a good match for any of LG’s WRGB panels, not just the B7 he made it for.
I use this exact ccss for my E6 (2016 model), along with an alternative white point provided by Dwayne (D-Nice).Speaking of Dwayne, he has done a number of calibrations across various LG OLED models and has developed alternative white points to help with deal with metamerism failures (measured white on multiple displays matching yet obviously different to your eyes regardless of equipment used). You don’t NEED to use any of these alternate white points. He mostly said these alternate white points not perfect but overall closer than without one.
For 2016 models he uses x=0.3039, y=0.3214 (except B6 and curved models I think)
For 2017 models, x=0.3076, y=0.3261 (except curved).To me his white point creates a closer match to my LG LM7600 (LCD) display, which looks much better than what I got trying to tackle metamerism failure by eyeball.
Zoyd also recommended one (x=0.3089, y=0.3284, for B7 used for his CCSS file above).
And Tyler Pruitt, from CalMAN (aka Wifi-spy on avsforums), also recommends one (x=0.3073, y=0.3214) but I don’t know what model(s) it was for.I’ve done extensive behavior analysis for my panel and have discovered a number of interesting behaviors, but I don’t have access to a newer model to check so these may not apply to your model. Here are a few things I’ve noticed that might effect others:
There are TWO kinds of “dimming” on the 2016 models, one of which we can turn off in the service menu.
This one is called “TPC” in the service menu, and is really a power savings/temperature regulator. It dims the screen if there is not enough “changes” to the screen for a period of time, screwing up measurements (think smartphone dimming after X seconds). There are various ways to enter the service mode to disable this (if interested, search avsforum for the thread titled “How to: Turn off ASBL on LG OLED TV”. If you have an Android phone with an IR Blaster I have a post in there with a remote layout for IRPlus (a free remote app)).
The other type of dimming depends peak brightness and how much of the screen is X nits. Basically use HCFR and measure 100% white in a 6% window and then in a 90% window.This 2nd type of dimming cannot be disabled at all, and should be much less noticeable on newer models.
If I use default options (Contrast 85, Brightness 50) no mater what I put OLED light at, there is always a ~65% drop in peak white between a 6% and 90% window (ex: 6% at 120 nits, 90% at ~45-50 nits!)
This dimming is controlled by CONTRAST, not OLED backlight.
My E6 can have contrast as low as 51 WITHOUT effecting image quality (50 and lower cause bit depth reduction).I use contrast 55, Brightness 51 and OLED at 67, giving me a ~120 nit white, and dimming does not happen until about an 80% window (a 90% window is ~100 nits and a 100% window is ~90 nits) which is a HUGE improvement.
Without this trick, actual content is always dimmer than it should be for 2016 models (many on avsforum calibrating for 170-200 nits for dark room viewing which gives an average peak in real content ~80-90 nits).Do you use any ICON modes, specifically the “PC” Icon? It is the only way to get 4:4:4 chroma (otherwise 4:2:2 is max for all other modes).
HDR + PC Icon mode = restricted to rec.709 gamut. This is a firmware issue that LG has not addressed. I downgraded firmware on my E6 to one that did not have this problem (read: PC Icon with bt2020 gamut for HDR, not rec.709). Gamut was changed after WebOS version 3.3.XXXX, so this effects any device with this so I don’t know if downgrading to fix this will be possible on 2017 models.For SDR, WIDE is the “native” gamut for 2016 models. I don’t know what it is for 2017 models, but you can use HCFR and run the 4-point luminance colorchecker pattern to see which gamut is correct (the 4 points should be in the same area of the CIE chart and not expanding or shrinking).
I’d also check how the COLOR control works as well. If you can increase it WITHOUT clipping, then do so until you have excess luminance on which ever RGBCMY is under target. Yellow was my lowest so I boosted color up to 60 (and now 65 since it was still under in the attached profile).Adjusting COLOR alone should get you 99.9% or 100% sRGB coverage. See what the default setting is for COLOR and GAMUT for the PC Icon mode with and the Expert Bright/Dark and use that as your starting point.
For my E6, this is 65+WIDE in the CURRENT firmware, but 55+NORMAL in the older firmware I went back to.To improve measurements, you need to manually insert a black pattern after every measurement.
These OLEDs are “unstable” by design (the thermal and voltage regulations done internally and a power circuit that would deliver cleaner and more stable power would go a long way here…), meaning everything shown in the last ~10-20 seconds is still present on the screen even if your eyes can’t see it.
This is VERY easy to see with HDR. Just show a dark grey (30,30,30) background in Windows and enable HDR. Then open the display’s menu and let it stay on the screen for about 60 seconds then close it and you can see the background glow where it was. This still happens with SDR, just not as noticable.Ted has a great post HERE on avsforums that covers this better than I can.
The profile I attached took ~20 HOURS to finish. With a black frame inserted after every other pattern, this display remains very stable, and there is no image retention/persistance happening allowing for even more points to be measured.
You should MANUALLY calibrate the display (grayscale only). You will not get accurate calibration results because of the stability issue mentioned above (no black frame insertion possible during “calibration” at this stage.
I asked Florian about this in another thread and he basically said to talk to Graeme about proposing this kind of thing for AgryllCMS. Until AgryllCMS gets it we’re stuck with manually adding black patches to the test chart.To improve profile results, based on my own experience only, I actually recommend AGAINST using Auto-optimized test chart and only use the “Vary RGB difference” and Interleave/Shift+Interleave patch sequences when creating any new patch sets. Again because of the stability issue mentioned above. Repeating this because it’s important.
I’ve had better results NOT using the Vary by Luma/Lightness sequences, because they gradually increase average panel luminance over time instead of trying to maintain a particular level from start to end. Stability issues on the 2016 models snowball very quickly the brighter the screen needs to be which is problematic.Again, please let me know if you want me to rephrase anything, it may not make sense to you and is likely my fault.
I don’t know what I’m going to do with HDR at the moment. The few test runs I did indicate that it will need some seriously long patch sets on my E6 and I’m waiting for a new version of HCFR where Zoyd has allowed for a max time of 2 minutes for black frame insertion (I THINK that should be long enough to do automatic measurements without image retention caused by 300+ nit patterns).
Either way HDR needs a LOT more measurements for these OLEDs in HDR because of LG’s funky tonemapping (in 2016 models this prevents manual calibration of EOTF as luminance is tied to WHITE sub pixel which is mostly controled by the BLUE subpixel and not green, causing a weird dip in green and spike in blue if adjusted to match EOTF up to ~690-730 nits).TL;DR:
a) Check display’s GAMUT options with HCFR, use whichever is largest (mine is SDR=WIDE and HDR=Normal).
b) Raise COLOR control until clipping happens, then lower by 2-5 (purpose: to have lowest of RGBCMY above target and over saturated while having NO clipping; mine is 65).
c) Manually calibrate grayscale, don’t “calibrate” with Displaycal
d) Insert black patches after every measurement manually (“export” as “0..255.csv” from chart editor and open with notepad, add then add 0,0,0 every other line, then drag’n’drop file back into chart editor).
e) ????
f) Profit!Vincent, just an FYI, the CCSS file used by the OP was made by Zoyd (HCFR dev). According to others on the HCFR forum it seems to be a good match for any of LG’s WRGB panels, not just the B7 he made it for.
I use this exact ccss for my E6 (2016 model), along with an alternative white point provided by Dwayne (D-Nice).I’ve no claims against its “accuracy”. My clains are:
-will a CCSS work with ArgyllCMS tooks if it is in RGBW order? IDNK, hence I asked Florian.
-it stores a emulated Rec709 gamut from WOLED backlight. I see no benefit from doing it in that way. All colors are are/should be a linear combination or native primaries spectral power distribution… use them as CCSS.
I remember a conversation in AVS Forum between Graeme and another one about this. Someone wanted to use specfiic correction taken from each OSD mode, Graeme wrote “Just use one taken at native gamut” and I think that he is right.
This one is RGBW emulated rec709 you want to use:
The text I pasted is just WRGB, same spectral information:
I see no point using them if you can use this one, but WRGB ordered if it is needed:
A native gamut CCSS will work for whatever OSD mode you use: P3, Rec709…
Do yo know if Argyll measurement apps (for i1d3) is order sensitive about CCSS? I mean, will Argyll tools work OK if you feed them with “RGBW” ordered CCSS like in OP’s 7zip file?
Order should not matter. A CCSS can also contain more samples than just WRGB, e.g. see CRT.ccss from ArgyllCMS.

Sorry, I didn’t mean to imply anything other than saying where it came from. There were a number of users, myself included, in the 2016 series calibration thread at avsforum where we were basically just using whatever us non-spectro users could find to see if it matched visually than what we were getting otherwise to help metamerism failure. Some were made wrong, others using the wrong observer, some with bad meters. I just wanted to let everyone know that this was from Zoyd so if anyone had further questions they would know who to ask. 🙂

I don’t understand this statement, but after my post last night I thought this might be related to the display firmware and/or Icon Mode the user is using.
My theory being to that it’s not the correct gamut similar to how the HDR gamut used ONLY for the PC Icon mode has the wrong gamut, and this was caused by a firmware update in the 2016 models (04.30.95 is fine and 05.30.02 and after all have a rec.709 gamut for HDR with PC Icon mode, other modes are fine). Whatever devices with WebOS version came with the latter seems to also have the same issue as per comments at places like MadVR thread at doom9, reddit, avsforum/avforum. I don’t know if downgrading firmware can be an option for 2017 models in this regard.Now, continuing on with my previous post.
I realized I forgot that I attached a short ti1 sequence (including black frames added).
The purpose of that was to start with this small set of 281 points with black frames inserted (523 total, takes 30-45 mins, estimated time on profiling tab is wrong).
Then use the resulting profile you made and set it as the pre-condition profile in the test chart editor and crank up the number of iterative patches and whatever else you want add. The idea being that this is like a ghetto version of to the auto-optimized cart.
Diminishing returns (DE2000) on my E6 started around 2000 points (~4000 total with ~2000 0,0,0 points, with ~2000 being actual patterns).
I have been including a full set (256) of neutral/grayscale ponts and a number vectors surrounding that axis hoping it will reduce chance of grayscale colorization in my profile test chart.
I’m still working on 70,70,70 and lower rgb values though, my OCD is not quite satisfied with results thus far.I generally don’t do this for LUTs but I found it absolutely critical that I needed to manually calibrate for my OLED display and not rely completely on the 3D LUT to correct grayscale or gamma/tone curve. My results showed too much error in grayscale that is not apparent if you focus exclusively on getting low DE values (colorization and a steppy luminance curve).
In the HCFR thread at avsforum, user Web Dove shared THIS video he made (his youtube link) which is quite useful for checking quality this range (0-30). This range also happens to be the area where the 2016 models are known to struggle with (can’t say for newer models).
The profiled I attached in the previous post is better than my manual calibration from a practical stand point. However I’m extremely OCD and I know there is still some room for improvement from my 2016 results. I simply have yet to find a combination of display settings and patch order that works best for the alternate white point I now want to use. This has been quite a tedious trial and error process (in retrospect I must have been really lucky in 2016).
Any 2017(8) models should be as good as that of mine, if not better.
