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 page77).
l Ensure the video source is properly connected to the projector.
l Press the Input button on the remote control or the Input Select button on the pen tray 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.
