Where ever you got your display it probably has some kind of control board so deal with that as best you can and find the needed pins. We'll need ground, v+ and av video signal line. thats all!
for the zero its easy to use the test pins under the usb to power it and the plug into the boost adapter since the display will be using much more power than a zero.
tuck everything into a nice case/box and connect your usb hub.
