4x1 HDMI A/V Switching Scaler with Gennum VXP 

Key Digital's HDMI4X1 4x1 HDMI Switcher (with HDCP) based on Gennum's renowned VXP video processor switches any of four (4) inputs of HDMI A/V to one (1) output, also conveniently switching multiple audio formats. HDMI 4x1 is much more than a switcher, as Key Digital's® Clear Matrix Pro technology based on the VXP can scale the selected video input to match the native resolution of your display. All the video processing features you'd expect from Key Digital® are also provided. Use the convenient front-panel display and pushbuttons, the IR Remote Control, or RS-232 to easily control all features of the switcher. The HDMI 4x1 processing is all-digital, providing the absolute best, crystal-clear, and pristine switching and picture quality you can attain.  The KD-HDMI4X1 features vertical zoom that's ideal for use with anamorphic lenses.

Key Digital processors feature RS232 port for expanded control for integration to home automation systems and computer control software.
