A Video Graphics Array (VGA) Extender (sometimes known as a VGA booster) is a device that increases the signal strength from a VGA port, most often from a computer, when it is necessary to run multiple monitors off a single VGA port, or if the cable between the monitor and the computer is excessively long.
VGA specifically refers specifically to display hardware first introduced as part of the IBM PS/2 line of computers in 1987. However, because of its later widespread use, VGA has also come to refer to an analog computer display standard, the 15-pin D-subminiature VGA connector or the 640'480 resolution itself.
VGA Extenders alleviate the problem of display quality loss associated with running multiple displays from a single source or extending the distance between computer and monitor. In such cases, pictures appear blurry which is why VGA extenders or boosters are used.
VGA extender allows long distance transmission of VGA video over standard Cat5, Cat5e and Cat6 cables while maintaining a crisp, clear screen resolution of up to 1900 x 1200.
VGA Extenders are ideal for hospitals, airports, schools, restaurants, hotels, conference centers and various commercial configurations.
