I would also guess the 5v. As I took a shuttle Wireless nic and turned it into a USB plug, so that I could use it with my laptop. I would think this would be the wire that would power the unit up and down.
I have a Lilliput on order and shoud get it on Monday. I have read and read, but can't figure out if it uses a VGA connector or if it does the Video through the USB. It states on the sites that I read about them at that the Video also came through a USB connector is this correct?
Here is the exact one that I purchased and the site its from: http://www.industrialflowerfactory.c...ail.php?o=1396
Here is what it states:
Touchscreen LCD VGA and Video
2 Video inputs plus 1 Audio input
VGA input (USB interface)
Ratio: 15:9 wide TFT screen
1,152,000 pixels(2400X480 dots)
stand for mounting included
