What is the purpose of the usb connection? It seems to link to the Pi but I can’t see how or why? Can you link me to any details?
That display needs two connections to the Pi to work:
- The HDMI connection provides the video information.
- The USB connection provides power and the capacitive touch interface data.
There are more details on the product wiki page from the manufacturer.
Many thanks, that clears it up
Would there be any issues with using this display with a normal computer just as a small monitor?
Hah! If you want to use a GUI, that might be challenging… The description says you can cram a virtual 1920x1080 into the 800x480 via software; it would be interesting to see how usable that is. But also according to the description, it’s plug and play, with native five touch support in Windows.
