Touch Extension Issues
When connecting your Clevertouch Board to your computer via HDMI or VGA connection, you may find that you are unable to control your computer via touch input from the board while the USB touch extender is connected. If this happens, check the ports on the right-hand side of the board. If your USB touch extender is plugged into the port labeled “TOUCH 1”, or is unplugged, plug it into the port labeled “TOUCH 2”. This should allow touch input to pass through to your connected computer.
Alternatively, connecting your computer via USB-C handles video, audio, and touch transfer all in one.
