Ultima HDTV Video Cables from Cables To Go are specifically designed for digital and next generation, high definition analogue video applications. The Ultima HDTV Video Cables are constructed from three individually shielded, 75-Ohm coax cables, which provide a performance connection that maximises colour and image. The Ultima HDTV Video Cable meets the rigid standards of everyday use. Please note: These cables are not compatible with Y/Cr/Cb video and are not compatible with all computer monitor ports. Make sure your graphics card supports Y/Pb/Pr component video or that your video source provides a YPbPr component video signal from the HD15 port to use this cable.
