Your image doesn’t fit the interactive whiteboard
If you’re using a SMARTUF70w projector with a wide screen interactive whiteboard, verify that
you’re using the correct aspect ratio mode for the interactive whiteboard:
Interactive whiteboard Aspect ratio mode
SMARTBoard M685 interactive whiteboard 16:10
You can set the aspect ratio mode using the Native DLP Resolution setting in the Projector Functions
menu (see Adjusting projector settings on page 12).
The image from your connected laptop computer isn’t projected
Laptop computer settings can interfere with projector operations.
Some laptop computers deactivate their screens when you connect a secondary display. 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 awall that
has obstructions, or if you swivel the projector too far from the vertical center of your interactive
whiteboard.
Use the SMARTBoard M600i6 interactive whiteboard system installation guide
(smarttech.com/kb/170555) 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
unaligned:
l Make sure that the installation wall is plumb and square and doesn’t move or vibrate
excessively.
l Make sure that there are no obstructions behind the projector’s wall-mounting bracket, and that
the bracket is firmly secured to the wall according to the installation instructions.
l Adjust the projected image. See the SMARTBoard M600i6 interactive whiteboard system
installation guide (smarttech.com/kb/170555) and Adjusting the image on page 19.
