The Home screen provides a list of sources that are available in the classroom. These sources will vary depending on the room type. In this image, you will see that you may choose to display the following sources

• Room PC (the instructor’s computer)
• Laptop HDMI (a cable to connect media that uses this type of connection like a laptop or an extra DVD player)
• Doc Camera 
• Air Media (wireless screen sharing)
• Wall Plate (additional HDMI inputs)
• Camera (room recording)
