g To resolve signal loss issues
1. Wait approximately 45 seconds for the image to synchronize. Some video signals require a
longer synchronization period.
2. Ensure that the image signal is compatible with the projector (see Video format compatibility
on page 27).
3. 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.
4. If your projector still doesn’t show a source signal, contact your authorized SMART reseller.
