Skew adjustment (X2-Silver and X2-Gold only)
The twisted pair cabling supported by the Gold Extender set (category 5, or
higher) consists of four pairs of cables. Three of these pairs are used by the
modules to convey red, green and blue video
signals to the remote video monitor. Due to
the slight difference in twist rate between
these three pairs, the red, green and blue video
signals may not arrive at precisely the same
time. This is visible as separate colour shadows
on high contrast screen images. This effect is
particularly apparent when using higher screen
resolutions and some types of category 5e
cables.
In this situation, the X2-Silver and X2-Gold
extenders provide internal skew adjustment
that can help to rectify the situation. The skew adjustment works by delaying or
advancing the timing of any of the red, green or blue colour signals so that they
are all delivered to the monitor at precisely the same time. For best results a test
pattern generator is available free of charge from the Adder website (see right)
and this should be displayed when using skew adjustment.
