VGA Distribution Amplifier: Real time relaying of one VGA signal to multiple devices simultaneously

A VGA Distribution Amplifier splits the video signal from one VGA source into two or more signals. It takes the signal from the source, amplifies it and then displays it on two or more VGA compatible monitors, displays or projectors. Working on plug and play functionality, this device can be installed in seconds. A user needs to connect the VGA graphic port on the computer to the amplifier’s input and the display devices to the output. VGA cables are used to secure these connections. The display devices which can be connected depend upon the number of ports the amplifier in use has. These devices are available in 2, 4, 8 and 16 port versions.

Depending on the model of the VGA Splitter, enhanced features are also available such as selectable gain and peaking, active PC audio buffering, and selectable input and output sync impedance. By daisy chaining two or more of these units together, a larger distribution can be achieved. A key feature of this amplifier is to boost the signal to the needed level thereby preventing signal loss and picture degradation. These amplifiers display the same image on multiple display devices simultaneously. They are available desktop and Rack Mount form factors.

Specially designed to work with specific type of video signals, these amplifier units come in composite video, S-Video or HDMI Splitter formats. The latter distributes the HDMI input into identical outputs in real time. HDCP compliant, these devices support 640x480,800x600,1024x768,1920x1200 resolution VGA video and HDTV resolution of 480i/576i/480p/576p/720p/1080i/1080P. The input video signals of these devices range between 0.5 to 1.0 volts p-p whereas the input DDC signals are 5 volts p-p. Even though different models have different sizes and weights, all versions are FCC and CE certified.

Since these amplifier units allow one computer to drive multiple monitors for simultaneous viewing, they are ideal for all applications that require high performance distribution of computer-video signals. The VGA Distribution Amplifier finds its use in training and monitoring facilities, conference and board rooms as well as in digital signage applications.
