I have an ACER GN276HL 3D Monitor. I bought an NVidia 3D vision 2 Glasses kit w/IR EMMITER. As I read the instructions in the owners manual of the monitor, under 3D setup it said I need an additional USB cable between the PC and monitor. It dose not say what cable. I chatted with ACER help, and they knew as much as I did. There is only one jack on the back of the monitor for something to plug into. It looks like a headphone jack, but I know it's not.
