I haven't solved it yet. I had read somewhere that if you have a Harmony remote, programming it to turn off the cable box BEFORE the receiver was the way to go... I gave that a shot but no-go. I might spend more time with it (ie: increase the delay between commands) but it is super-frustrating for sure.
Surely the box itself could use a permanent save setting as well - it's not like power is being completely cut off by the receiver (for example, the TV listings/channels are all there and dont need to be reloaded).
In the same way the receiver saves other preferences, the 4K box absolutely needs to save the UHD setting beyond initial set-up.
Sorry, that meant to say:
In the same way the *4k netbox* saves other preferences, it also absolutely needs to save the UHD setting beyond initial set-up.
