Optimizing the Video

Perform the following steps, in sequence, after you have installed the DDS. This procedure will help you to configure the scaler for the best settings for your display environment. In a multi-screen environment, perform this procedure for each display.

See Advanced Configuration menu earlier in this chapter to select and output a test pattern and to select and output blue only video.

See Picture adjustments, earlier in this chapter, to make adjustments to the picture quality.

See Memory Presets menu, earlier in this chapter to save presets.

1.

If you are using a digital display, such as an LCD or DLP projector, use the

 

alternating pixels test pattern as a reference to adjust the phase and dot clock

 

on the display devices. Proceed to step 3.

2.

If you are using a CRT display, use the cross hatch test pattern as a reference

 

to converge the display.

3.

Set the DDS to output either the crop test pattern for 4:3 video or the

 

appropriate aspect ratio test pattern. Use the display’s positioning controls to

 

position the image so that you can see all sides of the test pattern on the

 

display.

 

 

Do not use the DSS’s center controls to position the image.

 

 

4.

Select an input. Use the DSS’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 DSS’s

 

 

size function to correct the aspect ratio.

 

 

When sizing and centering a letterbox movie video source, increasing the

 

 

 

 

brightness on the DDS 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 RGB video inputs, set brightness and contrast levels. See Color/Tint,

 

Brightness/Contrast, Size, Center, and Detail adjustments, earlier in this chapter.

7.

Save this setting into one of the user memories using the DDS Memories

 

menu.

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.

All sizing adjustments to correct aspect ratio should be done using the DDS.

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 the 16:9 aspect ratio.
