I read about this in the 2016 P series calibration thread. It seems that anytime you change the Yellow brightness or saturation in the color tuner, you would see block pixilation in areas where there was yellow. All you had to do is bump it up by 1.Well I hope nothing is, or was, wrong with it, lol.
I had a tech replace two boards inside, and things seem to be better than before.
I have noticed some anomalies and wondering what everyone's thoughts are.
I keyed in your settings and things look great, however, in certain scenes I have noticed some severe macro blocking, almost pixelation, of certain scenes. This seems to happen when there are yellows, or brightness. And it seems to happen when using the warm color temp setting.
I have attached two images to see, from the movie 13 Hours on blu ray.
I am using all of your settings, and in the first image i use Normal color temp. In the second I use Cool.
You can see that with Normal, the areas around the fires look blown out and pixelated, and then in Cool they smooth out and do not show any issues.
Has anyone else noticed this behavior? I had a similar issue before, and ended up having to have two boards replaced inside. This issue doesn't seem as significant as before, but it's noticeable.
Anyone have any thoughts on This?
I apologize that the images are upside down, I was unable to fix it on my phone.
I noticed this with some of my earlier calibrations, but have not noticed with Rev 4.5 - at least on my set. Remember, that when you change the color temp, the TV loads a separate CMS table for that temp; and zeros out any settings that you inputted to the color tuner and 11 point. That is why the anomaly goes away. When you return to the normal temp, the TV reloads that CMS table with the settings, and the anomaly returns.
When I look at the Rev 4.5 settings, I made very slight adjustments to yellow in the Color tuner for Brightness and Saturation, basically bumping yellow about 5%. The variances between our panels might be why you see a yellow bias in some things whereas I do not; and the meter would have pointed that out to me during the calibration workflow. When I ran the saturation sweeps, yellow only needed a little help. Maybe on your set, it's already running a little hot.
TRY THIS and let me know: With the color temp set to "normal", go into the color tuner and set yellow to zero for both Brightness and Saturation. Yellow hue is already at zero. Replay that example scene again and let's see if the setting change cleared it up.
EDIT: Keep all the other settings for Rev 4.5 the same - just changing yellow.
