Hitachi's projection televisions are engineered to have the highest level of compatibility. Component video is a method of transferring video information using multiple, discrete signals. This allows video information to be transmitted as individual elements rather than combined together. It's the purest signal that TVs can receive today. Hitachi's projection televisions have component inputs that allow them to accept high performance video sources like DVD, satellite and digital tuners. All models are also built to receive multiple video/audio inputs, like composite, S-video (Y/C), and stereo audio, and can be connected to external audio systems for dynamically expanded audio performance. Hitachi's projection televisions include Auto Link, which detects an incoming signal and automatically turns on the television.??Hitachi's UltraVision Digital 61SWX10B HDTV Monitor delivers advanced digital television technology and high definition capabilities.
