Troubleshooting Component Video

This section contains important information about correcting problems that you may encounter with your HP Digital Entertainment Center Component Video Setup.

The component video connections are the green, blue, and red connectors, labeled Y, Pb, Pr, on your HP Digital Entertainment Center back panel. These three connectors combine to form a

quality Video Out. (They do not transfer audio.) There are several types of Component Video Outs. The HP Digital Entertainment Center supports YPbPr Component Video Out only.

Component Video Out requires specific configurations for certain display types and resolutions. You can adjust the display for component video using:

The display wizard. See “TV/Display Setup Wizard” on page 5.

Or

See “HDTV Overscan Compensation” on page 10.
