Setting Up A Dvd Source - Extron electronics ISM 482 User Manual

If you are using a digital display such as an LCD or DLP projector, use the
1.
alternating pixels test pattern as a reference to adjust the phase and dot clock
on the display devices. Proceed to step 2.
If you are using a CRT display, use the cross hatch test pattern as a reference
to converge the display.
2. Set the ISM to output either the crop test pattern for 4:3 video or the
appropriate aspect ratio test pattern.
3. Use the display's positioning controls to position the image so that you can
see all sides of the test pattern on the display.
For the best results of this optimizing procedure, do not use the ISM's
centering controls to position the image.
4. Select an input. Use the ISM's size and center functions to fill the crop or
aspect ratio test pattern.
If the input source is a DVD, set the DVD player to output a 16:9 aspect ratio
(see "Setting up a DVD source" below) before sizing the image using the
ISM's size function to correct the aspect ratio.
When you are sizing and centering a letterbox movie video source, increasing
the brightness on the ISM makes it easier to see the top and bottom of the
active video.
5. If the input source is RGB, use the horizontal and vertical detail adjustments
to increase the sharpness.
6. For S-video and composite video inputs, set the ISM to output blue-only
video and to output the Color Bars test pattern. Using the blue Color Bars as
a reference, use the ISM's color and tint controls to adjust the video's color
and tint.
7. For RGB video inputs, set brightness and contrast levels. See "Picture
adjustments", earlier in this chapter.
8. Save this setting into one of the user memories using the User Presets menu.
See "User Presets menu", earlier in this chapter.

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 causes
the player to internally scale and compress the signal. The DVD player's scaling
and compression defeats the advantage of having 3-2 pulldown detection in the
ISM.
All sizing adjustments to correct the aspect ratio should be done using the ISM.
To change the output aspect ratio of most DVD players:
Enter the DVD player's setup or action menu while the disc is stopped.
1.
2. Select the 16:9 aspect ratio.
