See our KnowledgeBase article on using your PC with an HDTV.

Converts VGA video output to Component video (YPbPr). If the source is a PC, additional software may be required. Recommended for multimedia PC and desktop PC applications.

The Model 9A60 allows a VGA-type RGBHV video source such as a PC or set-top-box to be connected to an HDTV display with YPbPr component video inputs.  The 09A60 permits HDTV images from  a PC (or other VGA source) to be displayed on an HDTV that is compatible with the image format being produced by the source. The 9A60 converter is not recommended for laptop computers.  For laptops, consider the model 1365 compact scaler instead.

If your VGA source is a computer, the 9A60 will make the necessary electrical conversion to component video, but computers do not normally use standard HDTV resolutions, so you must adjust the computer's output signal to be compatible with your TV. Third party software is required for video compatibility and image adjustment. For Windows, use PowerStrip by EnTech Taiwan; for Macintosh, use DisplayConfigX.

The 9A60 is not a format converter or  scaler. It simply passes the horizontal and vertical timings and image content to the output without modification. For example, a 1080i RGB video source  will require your HDTV monitor to accept a 1080i YPbPr component video input. Typically, 1080i, 720p and 480p sources, such as set top boxes, are compatible formats and will be displayed on HDTV monitors. However, not every combination of source and HDTV will yield an image.

If you are uncertain what formats your PC or HDTV can accomodate, consider the model 1365 compact scaler instead for these applications. The 1365 can scale a computer image to a compatible HDTV resolution, but software may be be required for over-scan image adjustment.
