Change the skew setting for an input or output as follows:
NOTE: For best results, set all three skew values to 0 ns (see steps 2a and 2b below)
before adjusting for misconvergence.
1. Use UTP cable test equipment or examine the displayed video image with a critical eye
to determine which video signal, red, green, or blue, is most shifted to the left.
TIP: A crosshatch test pattern is ideal for evaluating pair skew.
2. Monitor the displayed image. Increase the skew setting for the left-shifted video signal
2 ns at a time as follows:
NOTE: The skew compensation function cannot shift a video plane farther left than
the 0 ns setting.
a. Click drop box for the desired input or output and the desired video plane. A drop-
down scroll box appears (see figure 70).
NOTE: The red video plane is selected in figure 70.

b. Click and drag the slider or click on the scroll up button or the scroll down
button until the desired value is visible.
NOTES: • A 2-nanosecond adjustment is very fine. Up to 10 nanoseconds of delay
may be necessary before you detect a change in the display.
• As an alternative to step 2, or to watch a display as you make
adjustments, click on the up button or down button.
3. If either of the other video signals is misconverged, repeat steps 2a and 2b.
