Check your connections!

1. Check the cables and connections - make sure the cable you use is connected properly and solidly to your laptop or adapter.

All our classrooms have a VGA video connection. Many rooms, but not all, also have a HDMI connection. It is your responsibility to determine what type of connection your laptop uses and ensure your assigned classroom has the corresponding connection.

 This is a ANALOG or VGA connection
 This is a DIGITAL or HDMI connection

2. On the Podium Touch Panel, make sure you have selected the correct input button for your connection type.
