The box runs into a Vizio 5.1 sound bar then out to the TV with MonoPrice 4k hdr certified cables. One port on the Vizio izio says hdmi in, other hdmi out (ARC).
The other ports have my Shield on 1, Sony 4k 800m2 on 2, hdmi switch on 3 running a bunch of various things, X1 cable box non 4k on 4.
I'm beginning to think that the box and TV just don't want to play nicely together but I might be missing something considering how picky hdmi can be.
Occasionally it will come on fine in the morning but most times not.
Tempted to try and get a new 4k non dvr box to replace it anyway but would be nice to figure it out. The sound bar has optical and coaxial digital inputs as well.
