VGA switchers are designed for routing computer-video signals to a monitor or high definition display. Although VGA seems to be a dinosaur when compared to video signals such as HDMI or DVI, it is still used widely in multi-media meeting rooms, big screen display, schools and for other similar applications. There are many high performance VGA Switchers that are still in production used for cross switching multiple computers and audio signals.
The design of VGA Switchers uses the VGA 15-pin connector for the video signal I/O. VGA Switchers can easily be rack mounted; many come with rack mount ears. Many modern switchers have a front control panel, IR remote controller, RS-232 and the Ethernet control as an option. Laptops, desktop computers, graphic workstations are the usual sources for VGA Switchers. On the output end are projectors, TV’s and monitors that can be connected to the switcher. With the many video formats and resolutions, many VGA switchers have built in scalers that can upscale or downscale to a devices resolution specification.
VGA Switchers can be as basic as a 4 input by 1 output. Another type is a fixed input/output VGA matrix switcher that can be in a 4x4, 8x8, 16x16, and 32x32 or more chassis. A VGA matrix switcher will allow the user to control any input source and direct the signal to any output display. The next type of switcher for VGA would be a modular matrix switcher. A modular matrix switcher allows the user to mix and match inputs and outputs on any given chassis. A modular matrix switcher is a great solution for an application that is starting small for example, 4 inputs and 3 output displays on an 8x8 chassis; this option allows the user to add on more inputs and outputs in the future. Lastly, seamless VGA matrix switchers with PIP (picture in picture) feature are units that provide high performance switching and scaling of resolutions up to 1080p. In a professional environment, a true seamless switcher will allow seamless switching and selectable transition effects that will impress your peers.
Although the VGA era may soon come to an end, manufacturers are still developing high quality VGA Switchers. Many of these products have an EDID management system that is integrator friendly. We carry VGA switchers and also VGA matrix switchers (fixed, modular or seamless) from industry leading manufacturers such as Atlona, Kramer, Gefen, Shinybow, Avenview, Hall Research, TVOne and Vanco. Our knowledgeable representatives can assist and answer any questions you may have about choosing the right VGA Switcher.
