PureAV RazorVision video enhancement cable has been designed with your convenience in mind. It will allow you to quickly make adjustments that will bring your TV or projector's video capabilities to life. RazorVision optimizes both standard and high-definition video resolutions and supports computer-video resolutions as well. The PureAV RazorVision cable processes the video signal coming from your source device and selectively enhances contrast and other picture elements to provide more depth to the images on your screen. Unlike the contrast control on your TV, which adjusts every pixel on your screen equally, regardless of what the image is, RazorVision uses proprietary hardware and software to analyze the image and intelligently apply change. The end result is more depth, more realism, and a highly improved viewing experience.
