I also noticed if you are not running 4k then you get 4:4:4 chroma on HDMI 3 at 1080p, YAY for that one. That is also the port that i set the EDID information on, You can only seem to add it to port 2 and 3. Now some draw backs only being able to choose between 1080p 720p and one 4:3 resolution so i may undo that part. And tell linux manually what the tv is capable of and set my default on the boot loader onward as i lose a lot of possible resolutions doing it that way. I have to learn how to do that though. Live cds also have the issue so that wont fix it there though. Before tv would go out of range and monitor text be all garbled and screwy at the boot loader / grub onward until i logged in and fixed it by changing the tv resolution to one my graphics card can support.
We need a Smart TV Jailbreak. Please Please someone out there Jailbreak our tv's!
