I just put in a move order with upgrade to 4K. The rep on the phone seemed a little confused and kept talking about the small genie as my 4K receiver on my main TV. I kept explaining that I wanted the larger, HR54 box for my main 4K TV because the mini clients are stupid slow. I mean to the point of wanting to throw your remote across the room because you can't enter in 3 digits for a channel without it freezing and going to a 2 digit channel instead. It's an awful experience and one I shouldn't have to put up with period. But if I do, it better not be on my $1700 tv. The rep seemed very hesitant to explain any of this as it sounds like I would need 2 boxes at my main 4K tv? Is this really true?
