This is strictly an exercise in keeping the device (display, equipment) cool and happy.
As to the light sensors most are in the bezel along with the IR remote control receiver so you won't be covering up the bezel.
Also I find many disable the light sensor.
can you place an edge lit tv in an enclosed entertainment
center with open back for ventalation
was wondering if being enclosed that maybe the light sesors for the edge light might be somewhat blocked by the edge of the entertainment center
or would it be better to hang it or set on top of a stand vs having the sides blocked
