Comments:
The AMX 8 button panel also switches HDMI inputs on the projector. This was tested and the desktop auxillary audio input can be used when the HDMI options are selected on the projector. The video input from the desktop to the projectors does not work because this input has been connected to the projection room at the rear of the lecture theatre to allow Art staff to use alternative input devices.
