I apologize

I should have stated “it has optical cables in it”, which bend radius can affect

(Because the display sits flat on the wall, as in little to no space behind it, so the cable from display back to wall hole needs attention not to bend it too tight)

Yes maybe the copper is there to power the display?
Or add pull strength to the cable?
Or is the ARC Channel offering quadraphonic stereo?
Maybe just for electrostatic discharge?


Or is there a special ultrasonic infrared flux capacitor in that tiny yellow box that converts light to electrical power?
