I apologize in advance for even raising this topic again. 4K threads remind me of the endless negative HDMI threads we've all read and/or participated in. I did not attend Cedia this year, so I'm hoping someone saw or heard anything about 4K sources. Is there anything available today in the residential market that delivers 4K outside of the Sony 4K player? I hear about Directv offering 4K, but also heard it only works with select Samsung TV's. Is this correct? Our showroom DTV receiver won't even show the 4K channels in the guide. It is connected via HDMI to a Sony 4K TV for what that's worth. I also hear about Netflix streaming 4K. What source devices support this feature? Is this only available when using the internal Netflix app on certain Smart TV's? Are we all out of luck showing 4K DTV or Netflix content on a front projection 4K rig?
