Going into the Picture Settings, scroll down to Color Gamut while watching 4K content from Xfinity. What is displayed as the color space? Is it greyed out and unadjustable?
OK, so, to get to color gamut, I had to change the picture setting from standard to custom/professional so that pro settings were not greyed out. Once I did this, the colors came back from the change in picture setting. So, really, problem solved right there. But, I wanted to learn more, so, I went into pro settings and this opens up more options.
So, if by color space, you mean color gamut - it is not greyed out now and displays: Rec. 709.
There is also Contrast A.I., W/B detail adjustment, color detail adjustment and Gamma detail adjustment.
So, I will probably go back and run a calibration and/or run a bit different settings when watching 4K content(it's not like there is much stuff to watch right now anyway).
Thanks for the help!!!!!
Any other advice for picture on 4K is much appreciated!
Guess I can keep this display for now
