The Video Splitter is a signal booster and splitter that is used to take video input from a single source and direct it to four video outputs for monitors using digital/ analog DVI signals. The signal boost obtained by using the GVS164W6 allows you to not only split the signal but to extend the distance so that you can send the signal to about 215 feet away. This is no small feat, your average DVI card, over a standard DVI cable, sends a clear DVI signal approximately 25 feet. Dividing this between other displays reduces the video quality. This is why IOGEAR's video splitters are the best choice for allowing you to carry and split the video signal to more that one display with the same quality as the original signal. Bandwidth is the term that is used to describe the signal capacity of these units. In general, bandwidth is directly proportional to the amount of data transmitted per unit of time. These units have a bandwidth of 300MHz (which is 300 million cycles per second) and that is50 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 1600x1200 in 24 or 32 bit true color mode.
