Haha nice, you're the best person to be asking then.
So you do have your PC connected to HDMI 2 or 3, with an HDMI 2.0 cable, with Enhanced HDMI enabled on the TV? Its looks to be that way but I want to confirm.
This is almost a dealbreaker for me. Oddly though there wasn't really mention of this exact issue over in the
X800D thread at AVS forums so I asked there as well. All the people just seemed to mention not being able to get 4:4:4 chroma and all that, and they had to turn on the Enhanced HDMI setting so I wanted to see if it was related to this issue.
Seems like this would be a bigger deal to people. Do AMD users experience this as well? Xbox One S seems to be detecting native 4k correctly based on this thread, so that makes me wonder about the EDID thing. I may not get this TV as a result of this. :\
