These are real 4K issues Ken.
My initial plan was to edit and drive the 4K footage with an Apple Mac Pro that can drive 4K displays with HDMI. Not HDMI 2.0 yet, I believe.
That plan is now in limbo as the Mac Pro continues to be back ordered.
Now with both GH4 and Blackmagic 4K production supposed to be available soon. One wonders which really will be in the stores first.
Still, all three sub $3,000 cameras have issues. None can do 60p in 4K, have HDMI 2.0 or some sort of 4K recorder accessory.
Currently, you cannot put 4K content on an USB stick or hard drive to plug onto the Sony XBR65X900A.
Only ways to play 4K on the Sony are through the Sony Media Player, Youtube 4K files via Youtube Sony app and Netflix using the Sony app on the set.
Another is with a computer that has 4K resolution graphic cards. Not many can do 2160p at more than 24p. Mac Pro can do 2160p up to 60p. That will cost over $7,000.
So, we wait.
I still have the Sony FDR-AX100 on order from Sony and placed my name on both the Blackmagic and GH4 waiting list.

This is a question that's bothered me for some time since I'm planning on getting a 4K UHD TV this summer. There seems to be little out there in terms of knowing, with any degree of certainty, if a given type of personal 4K material (e.g. 4K camcorder output) can be played on a particular 4K display. We know the AX100 would be fine with the Sony, but what about a 4K display like the Samsung? What about the GH4 compatibility with a Sony?
I'm leaning heavily toward the 2014 Sonys and part of that has to do with their compatibility, media server and color palette. It seems that Samsung and Sony have slightly different philosophies in their 4K displays. Samsung 4K displays seems to lean toward a higher apparent sharpness whereas Sony leans toward a broader color palette. I'd like to retain the beautiful colors of the AX100 in 4K and whatever other capture device I might get in the future. But there is a concern that one capture device may have no way to output in 4K to a given 4K display.
I don't think compatibility with HDMI 2.0 clearly addresses this issue. Do you have any additional insight into this?
