Quick question. I have a x900e and ps4 pro. On the ps4 pro, it says that I am limited to 2.0 speed and so the YUV/RGB range is limited.
Can it be the cable which limit the maximum speed? Or do you think I am missing something else?
That should not happen.
Straight from the OP,

BASIC SET UP INFORMATION *************PLEASE READ**************
1) Connect your Pro or other 4k/HDR gaming devices into either HDMI ports 2 or 3. HDMI port 1 and 4 will not allow 4k/60hz w/HDR at full 4k.
2) Turn on Enhanced HDMI. Click the home button on your Sony's remote, scroll all the way down to settings. Go to input. Change HDMI to ENHANCED. This turns on 444 and HDR at full 4k.
3) Go to your PS4's settings -> Sound and Screen -> Make sure everything is on automatic. And then go to video output information and make sure it says : 2160p - 60hz. RGB HDR: 2k/4k. If it says something other than that, something is wrong.
4) You can leave many of the PS4's and TV's settings on auto. The TV and Pro do a good job of communicating with each other for the optimal picture depending on the software being used.
5) When playing HDR enabled content, the TV should automatically increase brightness (which is what it calls it's backlight setting) to MAX. If not, do it manually. Of course, when you exit out of HDR enabled content, the brightness should go back to your standard defaulted non HDR settings..)
6) Set the TV to GAME MODE pitcture setting to reduce input lag.

If you have followed these instructions and still have the error, yes the cable can also be the problem, particularly if it is long. Also, if you are going through an older AVR you would see this issue as well.
