i just tried it with a projector and used a digital camera as the control experiment
the bumblebee isn't mirroring the image
this is what i'm seeing when i use a digital camera and the bumblebee

this is with the digital camera
this is how i've connected the wires

the green wire isn't connected to anything
if i do connect the green wire to the black one (as per manual)

flickering image
the problem may just be me not knowing how to connect those wires to make it mirrored...
any suggestions?
