The CSC-750 Scaler is designed to upscale digital/analog video signals from Composite, S-Video, PC, Component (HD) and HDMI input sources, to digital HDMI output of a wide range of HDTV and PC resolutions including 1080p and WUXGA (1920 x 1200). As well as upscaling video, the scaler box also converts digital/analog audio signals to digital format, which can then be output either through HDMI combined with the video signal or separately via the discrete Coaxial S/PDIF output. The CSC-750 has a comprehensive on-screen display (OSD) menu that allows the user to select a variety of output resolutions and adjust them for the best picture quality. 2 year warranty.
