3-7 System 7SC • Operation and Configuration
Optimizing the System
For optimal performance, follow the steps in this section in order when setting up
the System 7SC 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 setup 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 will defeat the advantage of having 3-2 pulldown
detection in the System 7SC.
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.
