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 help image
synchronization.
2. If the image doesn’t synchronize, 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 they are
not causing the video signal loss.
5. If your projector still doesn’t show a source signal, contact your authorized SMART reseller.
