Abstract: Circuitry is disclosed herein for coupling VGA analog video signals Red, Green, and Blue from a computer to a first signal conditioning circuitry including signal splitting circuitry for providing two sets of the VGA signals. One set of these signals is provided to a color monitor located proximate the computer, and the other set is provided to a cable up to 300 feet in length and having a plurality of discrete conductors. The conductors are coupled at an opposite end of the cable to a second signal conditioning circuitry and to an analog monochrome monitor, the second signal conditioning circuitry including voltage reduction means for reducing the Red, Green, and Blue signals to a reduced, different voltage level for each signal. The reduced signals are then summed to form a monochrome video signal that is provided to the monochrome analog monitor, the color signals each displayed thereon as a different shade of gray in accordance with a reduction factor of each of the voltage reduction means.
