The StarTech. com PC99 3-in-1 Extension Cable allows keyboard, monitor, and mouse cables to be extended without the mess and tangle of 3 separate traditional cables. Our exclusive design takes 3 separate extension cables and fuses them into 1 neat tangle-free cable. Each connector end is color coded according to PC99 specifications for ease of identification when connecting the peripherals. The video component of the cable is constructed with high-quality mini-coaxial wire for crystal clear video quality at any resolution. Double shielding and a ferrite core on the video cable virtually eliminate any external signal interference. If a speaker extension is also required, check out the StarTech. com 4-in-1 extension cables.
