Alright, here are my latest re-do calibrations. 70 inch P, firmware 1.2.23
. Copy settings at your own risk, results may not be generalizable to your display and viewing environment.
This set is not at all an easy set to calibrate but I think we have made some significant strides as a group. Shout out to Goober as I used his ALZ on method to calibrate, as I think the picture looks better this way. Calibration was done in calibrated mode as I am in a bright living room during the day and then dark at night, suboptimal. 8% 100 APL patterns in Calman through mobile forge from a FireTV.
A note about calibrating colors on this TV. If you have CalMan tutorial or basic, do not even bother trying. You absolutely must have the color saturation sweeps or you really have no idea what your changes are doing to the majority of your colors. I also am retracting my previous statement about contrast needing to be at 49. It must have been an artifact of calibration from last time.
Backlight: Per your environment, 25-75
Color Temperature: Normal
Black Detail: Off
Active LED Zones: On
Reduce Judder: 0-3 depending on your sensitivity to SOE. I have mine at 1.
Reduce Motion Blur: I have this at 10 without any noticeable SOE. I have not done any detailed testing you to see if its really doing anything to my non-30/60 FPS content.
Clear Action: Off
Reduce Signal Noise: Off/low
Reduce Block Noise: Off/low
Game Low Latency: On for gaming, Off for TV / movie watching.
Picture Size & Position: untouched / n/a
Film Mode: Auto / n/a
Color Space: Auto
As above, do not attempt unless you are using Calman Control or higher or HCFR and have access to saturation sweeps. You likely will do more harm than good.
Here are the colors after greyscale but before color calibration. The little boxes are what the colors are supposed to look like, and the circles are what they actually are showing on the TV:
The entire focus on colors this time around was skin tones. I spent great care trying to dial in the low range of red with 5% sweeps, and overall kept dE (Delta E 2000) <3 until you get to 90+ when all bets are off anyway as this set is very inaccurate at 100% red as we all know. See my red chart below, you can see my error in the low range is outstanding. For the non-calibrators, what you are looking at is a 5% color saturation sweep, meaning a stepwise increase in the red color spectrum. dE is the overall error in the color (how far away from reference/what the color is supposed to look like). You want this as low as possible. My errors are <1 from 10%-40% in that sweet spot for skin tones, and otherwise stays pretty reasonable until it jumps the shark at the end. I am still not convinced they are perfect though unfortunately.
And here is the final color chart post-calibration. You have to make some concessions along the way, but overall color tracking is reasonable. Again, the the bottom middle of the graph is tracking the overall dE for each color point, represented by that color on the bar graph. We are pretty much <1 for most color points until you get to the 100% patterns.
11 Point White Balance:
Red Green Blue Cyan Magenta Yellow
Hue 0 3 -1 -1 0 -3
Saturation -8 -9 -5 5 -4 -9
Brightness 13 1 4 -1 2 0
Offset 1 2 1
Gain 2 0 -22
As above, calibration was performed with ALZ on and the Goober workflow.
Here is my greyscale after 2 point white balance, which was done at 30% and 100%. You can see the artifact of the ALZ on the gamma curve. The yellow line represents our expected/desired curve and the grey is the measured:
Here is the greyscale after 11 point calibration:
Red Green Blue
5 4 4 4
10 27 24 23
20 24 18 14
30 18 18 15
40 3 4 0
50 -3 -11 -9
60 -16 -18 -20
70 -15 -16 -11
80 5 6 6
90 3 5 -3
100 3 0 4
edit: Changed the 5% values, work in progress.
As usual, these represent a work in progress and will continue to tweak as I watch more content. My wife however is convinced I am a crazy person
