The GVS62 is a 2-port VGA video splitter and a signal booster with IOGEAR's patented VSE (Video Signal Enhancement) Technology. It is the best choice for splitting and carrying a video signal to more that one display with the same quality as the original signal. The GVS62 VGA Video Splitter is used to take video input from a single source and direct it to two video outputs for monitors using analog signals.The signal boost obtained by using IOGEAR's patented VSE (Video Signal Enhancement) Technology allows you to not only split the signal but it also amplifies the video signal to increase the transmission distance to about 215 feet away. This is no small feat, your average VGA card, over a standard VGA cable, sends a clear VGA signal approximately 25 feet.Operating with a bandwidth of 250MHz (250 million cycles per second) that is almost 60 times greater than a simple TV signal. The high bandwidth allows for the transmission of large amounts of information at a very high rate of speed, thus allowing for the use of high resolution settings upwards of 1920 x 1440 in 24 or 32 bit true color mode.
