Make sure the projector is on. The switch is near the HDMI port on the wall
Point the projector remote (bigger one) directly at the projector and press the power button. This might take a few tries, the green light will flash when successful.
Use the smaller remote to bring down the screen, press the middle button to make the screen stop.
Plug your laptop in with the HDMI cable.If you require an adapter please let IT know what adapter you need so we can make sure we have the correct one.
