Since I also recorded the game, I looked to see if my recording had any problems. Initially all of my recorded 4K content were showing up as 1080i. I rebooted my Hopper3 and the 4K recordings all played as 4K. After the initial reboot, the entire game played in 4K with no problems. This gets me to thinking that those who complain that they see no difference between the 4K content and normal 1080i may be watching in 1080i instead of 4K. I have now noticed 3 times that my Sony XBR-65X900E will play Hopper3 recorded 4K programs in 1080i. The solution is to reboot my Hopper3 and then the 4K displays correctly. It is probably a handshaking issue.
