First of all, I apologize in advance if this has been asked before (as I assume it has.) I've just taken the plunge into 4k televisions and am quite overwelmed with how complicated it's gotten. I've looked over previous threads and can't figure out what my best option is. My current setup (I am currently out of contract.) (1) HR44 (1) C41 (1) C51 (2) HR21 (on HD but not 4k tvs) All wired. I've purchased 2 4k tvs and plan to add third and am considering calling DirecTV about a 4k upgrade but I have no idea what to ask for. As best I understand it, if I get the HS17, then every tv uses a client and only 2 can have a 4k signal at one time. Can I connect 5 tvs to the HS17? I am not as familiar with the HR54, but understand that the primary tv it's connected to cannot receive a 4k signal? That doesn't work for how I have my house configured. So based on my current situation, what do you guys recommend if I want to have the ability to watch 4k on 3 tvs (not all at same time) and have HD on the other 2? Thanks!
