Step 6 — Peaking and Level

Adjust the image sharpness using the Peaking control. Increased peaking compensates for mid- and high-frequency detail loss. The LED lights red when minimum (zero) or maximum peaking is reached.

Adjust the image brightness using the Level control. View the image and adjust either control for the best image quality.

Step 7 — Skew Compensation

Pair skew can be measured with test equipment or by viewing a crosshatch test pattern. The SEQ receivers have built-in skew compensation capabilities. Adjust the equalization as follows:

A.Set the skew delay to zero for red, green, and blue by using a Tweeker or small screwdriver to press and hold the Select button for 3 seconds. When the Red, Green, and Blue LEDs all go out, release the Select button.

B.Use UTP cable test equipment or examine the displayed image to determine which video signal — red, green, or blue — is shifted furthest to the right.

C.Adjust the furthest left video signal by using a Tweeker or screwdriver to press and release the Select button until the LED for the left-shifted color lights.

D.Slowly rotate the Adjust control clockwise until the shifted color is properly aligned.

E.Repeat steps C and D to align the third color if needed.
