VGA Switchers are developed for directing computer-video signals to a given display. VGA stands for Video Graphics Array, and its popularity was adopted to refer to any analog PC display standard, the 15 pin VGA connector or its 640x480 resolution. Since its development in the 1990’s, the VGA interface has gone through an evolution of interfaces including SVGA, UXGA, SXGA and XGA. The refresh rates for VGA can go up to 70Hz. All formats use the same HD15 connector, and they all relate to the resolution a monitor supports. Many VGA Switchers support all VGA formats and high definition video including 1080p resolution unless stated on their manual.
