The PT-MA-HD44-QV 4x4 MultiView HDMI Matrix Switcher is the only completely independent HDMI system that can dynamically distribute four HDMI multimedia sources to up to 4 displays and arrange them individually in a total of 6 different modes, such as Picture-in-Picture or Quadview. Each source signal can be scaled individually and switched without delay or black screen. The HID input (mouse) offers extensive control features like cropping, drag & drop, and zooming in/out. The video wall function allows for the display of a complete image across multiple screens. This is the ideal solution for A/V switching, distribution, and transmission.
