CHAPTER 5
CABLES AND CONNECTORS

Minimum requirements and guidelines

Use only VGA cables that meet the following requirements:
Requirement
Have all pins in the
connectors fully
populated and wired
Are no longer than
23' (7 m)
In addition, look for VGA cables that meet the following guidelines:
Guideline
Have a gauge size
appropriate for the
cable's required
length
Have a minimum of
95% overall braid
shielding
NOTE
See Cable best practices on page 40 for general guidelines.

Third-party options

Details
The VGA cable connectors have multiple pins. Lower-cost cables might
not include them all, and this can cause operational issues.
Running a VGA cable longer than 23' (7 m) is not recommended
because it may degrade the video signal quality. To extend the video
signal properly, use a powered solution. See Video cable extenders on
page 65 for more information.
Details
When running a VGA cable less than 10' (3 m), a thinner cable
(about 12–15 mm) will work. However, use a thicker cable if you need to
run the cable 10'–26' (3–8 m). Consider using a cable that also has
smaller ferrite beads on the ends.
The cable's shielding should be, at minimum, a 95% overall braid or
even better, use a double braid with good bonding on the shell. The
braid should be either soldered or mechanically attached to maintain
constant contact. In the absence of a specification from the
manufacturer, you can only determine the degree of shielding through a
destructive test of a cable sample.
