Why USB port?

The VGA slot is important for connecting the projector to the device. You can find, however, that the external monitor already has a single VGA slot on your laptop. So, if you want the projector and the external monitor to be connected simultaneously, you have to have access to the USB port. In addition, for the same reason, you will also need a USB to VGA adaptor. On the other hand, most projectors come with a USB port, so you don’t need to worry about connecting to laptops via USB.
