What You Need to Know about VGA Cables
VGA or Video Graphics Array cables have been around for as long as we could
remember. These cables were initially designed for IBM computers, but have been
adopted by other computer manufacturers as well.
VGA cables are used to transfer information from the computer to the monitor.
More recently, they are used to connect computers (both PC and laptop) to TV
screens.
Considering that there are new cables, specifically HDMI, that are out on the
market, a VGA cable remains to be the widely used cable in households and offices.
Not everyone has adopted HDMI technology yet, and if everyone does, there will
still be a process where a VGA cable will still be used--but this cable is not without
a problem.
As with any other cable, the biggest hindrance that you could encounter when using
a VGA cable is signal transfer. It is frustrating to spend hours setting up your
devices and troubleshooting errors, only to find yourself dealing with a substantial
loss of signal. This usually happens when you use a very long VGA cable. Like any
other cable problems, however, this challenge is easily solved by purchasing a VGA
extender. A VGA extender allows signal from the computer to pass through without
problem. It is advisable that one use a VGA extender when running a cable that is
more than 100 feet.
Sometimes, the easiest way to prevent signal loss is to check the VGA cable for cuts
and twists. A severed cable, as you would expect, cannot efficiently transfer
information from computer to monitor. Make sure that your VGA cable is away
from places where there is heavy foot traffic or anywhere near children and pets.
Also, make it a point to check the connectors at both ends of the cable for loose
thumbscrews. Poorly fastened and wobbly connectors could lead to signal loss. To
restore the quality of picture, simply remove the connectors from the computer and
monitor, and insert them to the ports once again--this time, making sure they are
affixed properly and securely.
Another challenge for VGA cable users is that this type of cable does not offer audio.
You will need a separate set of cables that you will connect from the computer to the
monitor to get the sound that you need. With the introduction of HDMI cables,

which carries both video and audio, many are hopping over to the HDMI
bandwagon.
Though a VGA cable may have its snags just like any other cable, it is a winner
when it comes to price. VGA cables are inexpensive, and you can easily buy them at
any cable store. But as always, quality often comes with a price. If you need a long
VGA cable, make sure that you are purchasing the high quality ones. Spending a
little bit on VGA cables won't hurt, since you will be able to use them for a long
time.
You can purchase high quality VGA cables online. All you need to do is search the
Internet for a VGA cable and you will see different cables to meet your needs.
