Check your connections!

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 VGA and HDMI connections. 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

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

PROBLEM

The projector displays the computer background image, but not the presentation content.

     + 
    This should pop-up a Dual Display menu similar to the one below. Repeating the keystrokes should switch between the different dual display modes. Select “Duplicate” and press Enter.

PROBLEM

My presentation content displays OK, but there is no sound.

SOLUTION

    • When using the Analog VGA connection make sure the correct audio cable is fully plugged into the headphone jack of your computer.
    • When using the Digital HDMI connection audio is carried on the HDMI cable, do not plug in any additional audio cables.
      • Close the program playing the audio, then re-open it.
      • Try unplugging the HDMI cable, then plug it back in.
    •  For ALL connection types increase the volume in 3 places: On the content window (such as a YouTube video), the laptop’s master volume, and the Program Volume on the Touch Panel.
