Unknown/Unrecognized video source

Input measurement window

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:

1Connect the projector to the video source and make sure that the power is on.

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

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

4Check 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.

Input Measurements

V Sync: 72.00 Hz

H Sync: 78.00 KHz

Lines: 1057 Sense: HLHL

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.

5In the Source mode menu, select the source mode closest to the values recorded in the preceding step.

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

7Close the menus to save these settings.
