Questions
Is there anything I should do to optimize the
video quality for my particular cable?
LongView automatically tunes its circuits to
optimize video performance for your specific
cable length. However, for optimum performance
at the maximum distances, particularly for high
video resolutions, Cybex cable or Belden 1583A
or 1585A Datatwist is recommended.
Category 5 cables have different twists-per-inch
rates for the four pairs of wires within a cable to
reduce crosstalk. These rates vary by
manufacturer. In cases involving maximum length
cables and high video resolutions some
manufacturers’ cable may cause the red, green,
and blue colors to be “misaligned” such that a
vertical white line shows up as a vertical line of
two or three colors in parallel. In this case, you
may be able to improve the video by making your
category 5 cable more closely match Cybex or
Belden cable by using a special adapter available
from Cybex.
Note: Before modifying your cable, connect your
monitor directly to your computer to verify that
any misalignment is not caused by the computer
or the monitor. If the problem persists, contact
the manufacturer of the monitor or the video card
for assistance in improving your video quality.
If the problem was solved when the monitor was
directly connected to the computer, you may
have a power problem. See Appendix B for
information on troubleshooting power problems.
If you wish to proceed to optimize your cable,
contact Cybex Customer Support, describe your
problem, and inquire about a special adapter.
