itself at approximately 4AM unless a movie is playing on the unit.

Gefen & Atlona both make EDID learning devices which are small adapt-

very popular solution, another simple solution is to use a small HDMI switch
which maintains EDID. Be sure to remember NEVER to hot swap or plug
and unplug HDMI cables when equipment is powered up!
