Troubleshooting your interactive whiteboard system
Some laptop computers deactivate their screens when you connect a secondary display device.
Refer to your computer's manual for details on reactivating the computer's display screen.

Unaligned projected image

Alignment errors occur when the projected image isn't perpendicular to the screen. Alignment errors
can occur when you mount your interactive whiteboard system on an uneven surface or a wall that
has obstructions, or if you swivel the projector too far from the vertical center of your interactive
whiteboard.
Use the instructions in the included SMART Board 480i5 interactive whiteboard system installation
guide (smarttech.com/kb/170553) to eliminate most image alignment issues.
The projector image can slip if the projector is moved often or installed in a location prone to vibration,
such as next to a heavy door. Follow these precautions to help prevent the image from becoming
misaligned:
Make sure that the installation wall is plumb and square and doesn't move or vibrate
l
excessively.
Make sure that there are no obstructions behind the projector's wall-mounting bracket, and that
l
the bracket is firmly secured to the wall according to the installation instructions.
Adjust the projected image. See the included SMART Board 480i5 interactive whiteboard
l
system installation guide (smarttech.com/kb/156695) and Adjusting the image on page 19.
