Ah, you re-posted an earlier graph - I missed that, and was therefore confused.
Hi,I have updated the download link for the HDR10 patchsets.
You can find these two additional CMS patchsets if you re-download the ZIP, useful for HDR10 manual cal:
HDR10 CMS 50% REC2020 @ 100 nits
HDR10 CMS 50% REC2020 @ 203 nits
(50% of WRGBCMY @ 100 nits, aka 50% SAT / 50% STIM REC.2020 HDR10)
I don't think it will work because LG has a broken CMS processing of the regular TV CMS controls.Okay,btw
Can LG OLED'S HDR 10 be manual cal CMS?
On the older version of ColourSpace, I encountered color discrepancy as mentioned by @thoth when I first calibrated at video range (with 0-255 patches scaled by CS), then calibrated a PC input on the same display at PC range (full 0-255 patches without scaling). To my surprise, I found I needed to make adjustments to RGBCMY CMS controls, 75%/75% patches were off, all in a similar deviation from the video range settings. At the time, I passed this off as the display doing some transposing between limited and full range inputs.The small inaccuracy was affecting the verification (when Video Levels patchsets was used, for full range was OK), not the manual CMS calibration.
The issue has been fixed with ColourSpaceZRO 188.8.131.525 release, so now, it has bit-perfect the custom patchlist import and target calculation.
Now the patchsets are not scaled.
About the Dark Skin patch used as an example, at the right side of the picture, below you see the HDMI capture of the PGenerator signaling. (ColourSpace patchscale 16-235 / PGenerator RGB-Full)
Ted, thanks for this.1000 Point volumetric verification run using ColourSpaceZRO
A question for the more experienced calibrators -Here are the post calibration results for Sony 65X950H, in Rec.709 gamma 2.2. Manual calibration by me.
Hi,A question for the more experienced calibrators -
The CMS blue hue setting that gives me the plots above results in a noticeable band in the color ramps gradient (the vertical color ramps pattern on Ted’s iso). However, fixing the band visually requires setting the hue slider in a position that results in higher dE for several points in the 1000 point color checker. Essentially the tangent for those points are now in the wrong direction instead of “on axis”.
Which one do I want to prioritize? Lower dE or a smoother gradient in the test pattern?
Hi,Which patch/triplets are recommended when doing a two point HDR white balance on an LG CX? Also, is disabling the tone mapping recommended?
