Unknown/Unrecognized video source

Occasionally, you may encounter an unknown or unrecog-
nizable video signal while using the projector. If this should
happen, use the following steps to connect and adjust the
projector:

1 Connect the projector to the video source and make sure

that the power is on.

2 Select User A or User B for a custom setting (Advanced

menu).

3 If it is not already selected, select Computer input from the

Source menu.

4 Check the Input Measurements window and record the V

Sync, H Sync, and Lines values for the incoming video sig-
nal. Consult your computer documentation for the Video
Data Rate (dot clock) specifications.

Note: The Lines value is larger than the vertical lines of
data displayed. This is due to additional vertical lines that
are sent by the video system for video processing timing
purposes.

5 In the Source mode menu, select the source mode closest to

the values recorded in the preceding step.

6 Make adjustments as necessary to fine-tune your display.

7 Close the menus to save these settings.
