The 1/4 inch square board adhered to the back of the case 4 inches to the left of power cable hole 1/2 inch to the right of 1 1/2 inch square black foam adhered to the case. Can be seen in image #20. The connected two thin wires are routed up and around hinge assembly. It connects to the second port down on the visible side of the motherboard. The port is on all motherboards but I have only found one display that has this small board, all other displays leave this port empty and do not have this configuration.

the thin 2 wires with the small board attached and adhered to the case a few inches to the left of the power cable hole. I have only found that on one monitor though they all have the port on the motherboard it is just empty on all the ones sans the thin wires and board adhered to the case. My question is... What is it and why is it not on all the displays??
