Toggling Between Desktop Computer and Laptop / iPad 

The desktop computer is the default computer source for the classroom. However, the auto-switch will automatically send the audio-video signal from the most recent connected device. If that device is disconnected, the auto-switch will revert to the last connected device / next available source. If there is a need to manually toggle between the desktop computer and the laptop, press the HDMI OUT button until the desired source is selected.
