      • Reported to cost less than 12usd
  • Diverging Lens?
  • USB to LCD processing ICs

Laptop to projector connectivity

  • Can the laptop talk to the projector via an exported X session instead of USB-to-VGA dongles? The projector will need to have receiving equipment (wifi or USB) and be able to run the exported X session on its LCD.
