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 compatibility on page 27).
l
Ensure that the video source is properly connected to the projector.
l
Press the Input Select button on the remote control or ECP 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 is not detected, out
of range of the projector’s support video
modes or 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 synchronise. Some video signals require a
longer synchronisation period, cycling back through inputs to the one that you want also
helps image synchronisation.
2. If the image doesn’t synchronise, check the cable connections to the projector and the ECP.
3. Ensure that the image signal is compatible with the projector (see Video format compatibility
on page 27).
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
that they are not causing the video signal loss.
5. If your projector still doesn’t show a source signal, contact your authorised SMART reseller.
