VGA Extenders
A VGA extender is a device that extends a VGA cable’s range without sacrificing quality. VGA extenders are often used in audio/video applications that require a source to be connected to a display device over a long distance. They are usually in the form of a small box and can often extend a VGA connection over 300 feet. VGA extenders may also include other features, such as converting VGA signals to other types of cables.
How VGA Extenders Work
VGA extenders are made for VGA (Video Graphics Array) cables and consist of a small box with a VGA cable connected to each end. One VGA cable is connected to a source, usually a computer, and the other is connected to a display device, such as a monitor or projector. VGA extenders create a bridge so that the input VGA cable’s signals can safely pass to the output VGA cable without interrupting the connection.
Applications
If someone wishes to connect a computer to a projector in another room and the projector is incompatible with wireless technology, he/she can use a VGA extender to run a VGA cable along a wall or floor and into the other room without limitations on quality or distance. VGA extenders can also be used in situations that involve connecting a VGA-based input device to a display device that is not compatible with VGA. This is because VGA extenders have multiple types of cable connections and a method of converting signals between one cable and the other.
Advantages
VGA extenders are relatively small and can usually be set on top of a counter or desk in between the input and output devices. They are inexpensive and can be outfitted with a variety of cable connections in order to transfer signals from a VGA-based device to a non-VGA-based device. Additionally, VGA extenders have the primary advantage of extending the distance that a VGA cable can be stretched across. This increases a display device’s mobility and use if it is not equipped with other means of transferring data, such as wireless technology, a direct line-of-sight infrared device, or more popular connections such as USB or Ethernet cables.
