Following up on Ian’s comment above, Look at the Sony X800 for example. You can can take the picture to the TV in 4K. Seems the digital coax output will output multichannel bitstream according to the manual pages 22 and 23. Unclear if this will be 96K high-Rez or converted to 48K.

I don’t have a 4K TV or 4K player so could very well be mistaken. Someone here should know. Will a 4K TV have a multichannel capable coax or optical output?
