The 3250HD can output video to the HDTV display in four resolutions:
480i, 480p, 720p, or 1080i. These resolutions, or scan rates, allow consumers
to select the scan rate best suited for their HDTV set. Consumers can
stretch and zoom the video picture to maximize its viewable area on the HDTV display.

For added connectivity, the 3250HD offers optional loop-through that provides
a set of component HDTV inputs, a composite video input, and both analog audio
and optical digital audio inputs. A consumer with limited inputs on their HDTV
can use the loop-through connectivity feature on the 3250HD to connect additional
