4k Box detecting wrong resolution upon startup

The 4k box reverts to 480p SD resolution upon restart after the television has been off for a few hours. This started happening about a week ago. Is there a solution, other than correcting the device video setting every time?

is your 4k box connected via HDMI directly to the TVs HDMI1 or HDMI2 (see owner's manual) connector?

It is connected directly via an Audioquest HDMI cable.

this has been reported by several others (one connect) as an issue.  The set top box needs to read the EDID (extended device ID code) from the monitor ((TV in this case). apparently the one-connect device does not keep/show/remember/allow reading the TV's EDID so the set top box resets. Sent many to Samsung's forum but no one has replied to the fix if any. Is there an extra HDMI on the TV you can connect to directly with the set top box?

What's interesting/odd is that on the video display screen that allows you to amend your resolution settings, the connected device illustrated in the upper right hand corner is Samsung 4k UHD TV.  That would lead me to believe that the Xfinity box is recognizing the device yet still displaying 480P resolution.  Unless, this is something that remains there from initial setup?

on your cable bill, do you see a line for HD technology fee or in the package description 'includes HD technology'? 

The package description does include the HD Technology Fee.
