Connecting to a Computer for USB Mouse Control
If you connected your computer to a Computer, USB-B, or HDMI port on the projector, you can set up
the remote control to act as a wireless mouse. This lets you control projection at a distance from your
computer. To do this, connect the projector to your computer using a USB cable, if it is not connected
already.

2. Connect the other end to any available USB port on your computer.
