SYSTEM
Resolving Image Issues
Computers, peripherals, source inputs and their connection cables may not be set up
correctly to transmit their signals to your SMART Board interactive whiteboard system.
Refer to Video Format Compatibility on page 34 and the following section to help
resolve these issues.
Loss of Signal
If a visual source signal is lost or if
the signal is being switched to a
different device or input, the
projector doesn’t show a source
signal and instead displays the
SMART logo on a blue screen.
To resolve
loss of signal issues
1. Wait approximately 45 seconds for the image to synchronize. Some video signals
require a longer synchronization period.
2. If the image doesn’t synchronize, check your cable connections to the projector
and the ECP.
3. Make sure that the image signal is compatible with the projector (see page 34).
4. If your projector still doesn’t show a source signal, contact your authorized
SMART reseller .
