Connecting to Projector in 2120 or 2122 Vilas

2120 and 2122 Vilas have identical projectors and connection options.

Instructor iMacs are connected to the room projector via HDMI. To use the projector simply power on the projector using the remote in the room. The projector will seek out the active display connection. Audio for the HDMI connection is sent to the projector from the iMac’s headphone port through the audio cable matched with the HDMI cable.

When connecting a device to the VGA connection, connect your device to the available VGA cable and connected audio cable, and power on the projector. The projector should find your device’s connection.

Volume is controlled using the projector remote.



The projector has no display:

  1. Is the projector powered on?
  2. Are all cables properly connected?
    1. The instructor iMac should be connected via HDMI in the back of the iMac. The connection should look like the image below (click the image to enlarge).IMG_0035
