http://www.cablewholesale.com/products/dvi-products.php | DVI to VGA and VGA to DVI adapters can help newer computers and older monitors, as well as older computers and newer monitors, work together. Getting the right cables and a good quality adapter is important for several reasons that we’ll detail in this document.

1. DVI vs. VGA: What’s The Difference?
VGA (Video Graphics Array) and DVI (Digital Visual Interface) connectors transmit video from
your computer or other output source to your television, monitor, or projector. VGA is an older
technology, but it is still commonly used. DVI is newer and is rapidly supplanting VGA.
The primary difference between VGA cables and DVI cables is that VGA cables transmit analog
signals; DVI cables carry analog and digital signals. An easy way to distinguish DVI and VGA
connectors is by color – VGA connectors are typically blue while DVI connectors are normally
white.
In VGA connectors and DVI connectors alike, signal quality is affected by the distance the signal
must travel. The longer the distance, the more signal quality will degrade. DVI cables can run for
longer distances than VGA cables with less quality interference. DVI boosters can help mitigate
signal degradation in long cables.
Other factors can also impact signal quality. VGA cables are more vulnerable to electrical
disturbances than DVI cables, meaning that a VGA cable running close to other cables may
experience a decline in signal quality.
Although DVI is the newer technology, there are some advantages to VGA monitors. VGA
monitors represent fast motion better than DVI, and also more accurately represent color,
keeping these monitors popular among graphic designers and some gamers.
Differences in equipment may make adapters necessary. Some older computers still in service
may only have a VGA port, making an adapter necessary if you have a newer monitor. A VGA
to DVI adapter can connect the computer and the monitor, allowing them to work together.
Although a VGA to DVI adapter will make your older computer’s video available on a DVI
monitor, the picture quality will not be DVI quality.
If you have a newer computer and an older monitor, you can convert DVI-A signals to your
VGA monitor with a DVI to VGA adapter. Quality will also be an issue with this connection.
Good quality cables and adapters can make a world of difference when it comes to signal quality.
When purchasing cables or adapters, be sure to read online reviews of the manufacturer you’re
considering, as well as reviews of the company’s products themselves. By doing a little quality
control, you can avoid buying faulty, cheaply made cables that won’t get the job done.
