Optimizing the System

For optimal performance, follow the steps in this section in order when setting up the USP 405 and its input and output devices.

Setting up a DVD source

To get the best results when using a DVD as a video source, Extron recommends that the DVD player itself be set up to output an aspect ratio of 16:9 and not 4:3. Because all DVDs are mastered as 16:9, having them set up for anything else will cause the player to internally scale and compress the signal. This scaling/ compression by the DVD player defeats the advantage of having 3-2 pulldown detection in the USP 405.

To change the output aspect ratio of most DVD players,

1.Enter the DVD player’s Setup or Action menu while the disc is stopped.

2.Select a 16:9 aspect ratio.
