Students are moving the table closer to the booths or trying to connect other devices to the plugs on the pillars. If this happens then the TV has been turned off. There is a remote in the Tech Bits tub in the workroom.
When initially connecting your device to the Media Scape display, the puck may sometimes not light up with your number to connect. If this happens, disconnect the puck and try again. If this does not resolve the problem, hold down on the power button located in the puck's storage tray area. Then turn it back on.
Hit Flag + P to pull up the projection options. Most people will want to Duplicate their screen. More information
There is no sound. We have headphones that students may check out to use on their device or on our computers if they need to listen to a video.
That being said, someone may have turned up the volume. Grab the remote and turn it all the way back down to zero. :)
