I normally wouldn't cross-post the same thing in two threads, but I think with this thread being RVU there is a benefit to having this post in it for future readers:
I also had a 4k upgrade today as part of my movers deal. I was upgraded to a new dish with the RB LNB, HR54, and had them install two Samsung KS8000 2016 4k RVU TVs.
The first thing the installer did was discuss changing to client C61k instead of using RVU. I shared that I had read/discussed with 3 people using the 2016 Samsung on RVU and they are satisfied. In fact one has a RVU and a C61k and said they are almost the same but the RVU being slightly faster (which is hard to believe).
I'm happy to report that I am impressed and quite satisfied with the RVU setup. The interface response is adequate and comparable to the client box (slightly slower than the genie). Like the client boxes the UI seems to be standard def graphics. The channel changing and starting of playback is comparable to a client and starts most things in 2-3 seconds. Slower than the Genie but functional.
I like that with it integrated into the TV everything is native resolution without really delaying for the receiver/TV to change resolutions. It seems to flow between resolution changes (including 4k) pretty well.
The RC73 remote works well and operates just like on the client/genie.
I am glad I went with the RVU setup, it is smooth and no client box. So far it operates just as well as my C51 did.
I received a HR54 upgrade, free HBO/Max for 3 months, and free Sunday Ticket Max for 2016 as part of a mover's deal as we bought a new home and moved recently. They did offer C61k boxes for free, but I really wanted to try the RVU on these new TVs and they did not have an option to do that install for free. They did give me one free, so I paid $49 for the two RVU installs. The RVU install is essentially connecting a broadband DECA to the wired ethernet port on the TV and activating it as a client box. I could have done this myself, but many customers could not, and I understand why they require installation for RVU.
I did watch a replay of the Olympic basketball game from yesterday for a few minutes and the picture was spectacular. I feel like it is 2006 again and I'm anxiously awaiting the launch of additional HD channels, but now 4K. I would imagine that ESPN and HBO may be some leaders in this, but haven't ready anything about them moving into live 4k broadcast. Lastly I would share that 4k is working with my Xtra package, and I hope it stays this way as I have no interest in Ultimate and would likely end up going back and forth when there is live 4k programming I want to watch. Requiring Ultimate is a ridiculous requirement and I hope DirecTV reconsiders this decision.
