The ADP-MV-1117 is a professional-grade HDMI 4×2 Quad Multi-Viewer and Matrix Switcher. This device is designed to take four different HDMI input sources (like cameras, PCs, or media players) and display them simultaneously on two separate screens.
It is particularly valued in security monitoring centers, broadcasting studios, and high-end conference rooms because it supports a smooth 60Hz refresh rate, ensuring that motion remains fluid across all windowed views.
