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 29).

l Ensure 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.

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. 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 29).

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.
