"This SXGA/UXGA Monitor ""Y"" Splitter cable provides an inexpensive alternative for splitting the video signal from your PC's VGA port to two high-resolution monitors that use standard 15-pin plugs. 75-ohm coax conductors used for RGBHV signals allow for use with monitors with up to 1600 x 1200 resolutions. Perfect for laptops to display on a separate, larger monitor. Use for short-distance applications only. For applications that require longer distances and highest resolution, see B114-002-R or B114-004-R."
