C61K 4K output mode
I'm trying to connect a C61K to two TV's via a HDMI splitter (CELabs UHD 260). Both TV's direct connect fine and will run 4K but when I introduce the splitter it all falls apart. The Sony Z8H goes black and loses the input anytime I bring up the menu or guide.
It seems like the C61K is flipping to 720P at certain times causing the TV's to lose the HDMI/HDCP handshake. I've tried removing 720P as a display resolution but it keeps coming back.
@TexasBrit any ideas on this one? I've tried three different HDMI splitters so it seems to be something the C61K doesn't like.
Thanks

HDMI splitters are a mixed bag, especially for 4K video. You've tried three different splitters, so you may just need to try another one.

At bare minimum what the TV needs to support along with the powered HDMI splitter is HDCP 2.2, HDMI 2.0, and 60 FPS. However, there is no guarantee as it was not intended for this setup. DirecTV has been built to connect boxes directly to their TVs which you pay for each authorized TV. Splitting to multiple TVs is outside of their billing model and equipment setup so is always at your own risk.

Both TV's are definitely HDMI 2.0, HDCP 2.2 and 4K/60. The weird thing is it is fine until you bring up the DirecTV menu or channel bar, that's when the C61K wants to go back to 720P.
@ litzdog911 I ran it like this way for years using component cables so that's how my family has been trained to use it (unfortunately). It was stupidly simple for all that time but now it's become a real thorn. I guess my next steps are to buy a non-4K splitter or breakdown and run another coax for another receiver which is the least palatable option.
Thanks again for the ideas!

The issue is that networks now require High-bandwidth Digital Content Protection (HDCP). What the intention from this is to prevent people from recording HD (or higher) content. Even if the splitter is compliant, the further problem is HDCP is finicky when it is not a direct connection.
Think of it as a secret handshake. If one device in the chain messes up, then info is not communicated. The days of splitting simply with no requirements are dwindling. The digital world does have a bit more control.
If you do have them install another box, on the plus side you aren't forced to watch the same thing as the other TV. If you have the HR54, though you can get another C61K, you can only have one of them tuned into a 4K channel at a time. Alternatively, you could see about an HDDVR to gain 2 tuners and 500GB recording space so you don't eat another tuner from the Genie. If you have the Genie-2 (HS17), then Clients is all it allows. Whether HDDVR or Client, it is $7 for the additional TV either way.
