Resolving image issues
To resolve common image issues, complete the following tasks:
l Ensure the computer or other video source is on and set to display a resolution and refresh
rate supported by the projector (see Video format on page61).
l Ensure the video source is properly connected to the projector.
l Press the Input Select button on the remote control or the projector keypad to switch to the
correct video source.
If these tasks don’t resolve the issue, refer to the following sections for additional troubleshooting
information.
Loss of signal
If a video source signal isn’t detected, if it’s out of range of the projector’s
support video modes 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 signal loss issues
1. Wait approximately 45 seconds for the image to synchronize. Some video signals require a
longer synchronization period. Cycling back through inputs to the one you want also helps
image synchronization.
2. If the image doesn’t synchronize, check your cable connections to the projector.
3. Ensure that the image signal is compatible with the projector (see Video format on page61).
4. If there are any extension cables, switch boxes, connection wall plates or other devices in the
video connection from the computer to the projector, temporarily remove them to ensure
they aren’t causing the video signal loss.
5. If your projector still doesn’t show a source signal, contact your authorized SMART reseller
(smarttech.com/where).
