Skew equalization
Skew exists between wire pairs when the physical length of one wire pair is different from
another. Skew affects the displayed image when the differential length between wire pairs
exceeds 2 feet. This causes the timing of the red, green, and blue video signals to appear out
of alignment (horizontal registration errors). The signals transmitted on the shortest pair are
shifted to the left if you are viewing white lines on a black background. A white vertical line
on a black field can appear as individual red, green, and blue lines that are close together.
The signal transmitted on the shortest wire pair leads the other colors and appears to the left
on the display. As the transmission cable length increases, the skew effect increases.
