DISPLAY LAPTOP

VGA

1. Remove 15pin VGA cable from the rack drawer located in cabinet or black box.
2. Connect your laptop, using the cable, into either the LAPTOP 1 or LAPTOP 2 input jack.  If using Computer Audio, please also connect the 1/8” stereo mini connector to both your laptop and the wall jack.  If you are using a Mac laptop, you will need to provide your own VGA adapter, as Classroom Technology Services does not provide Mac adapters.
   LAPTOP inputs vary in location, but are most likely located at the front of the room and/or in the equipment rack.
3. Turn on your laptop.
4. On the Extron control panel, choose the LAPTOP button corresponding with where you plugged in the cable (LAPTOP 1 or LAPTOP 2).  Even if this button is already lit, deselect and then reselect it now.

1. Connect a DVI cable to your laptop and the DVI input jack (if you do not have your own DVI cable, please contact Classroom Technology Services at (617) 353-3227).
2. On the Extron control panel, choose the DVI input button.
   DVI capabilities exist in only the following rooms:  PSY-B47, SOC-B65, SOC-B67 & STH-B20.

DISPLAY DVD OR VCR

1. Insert your DVD or VHS tape into the player.
2. On the Extron control panel, press the DVD or VCR button, depending on which you want to display.  Even if this button is already lit, deselect and then reselect it now.
