Technical Overview
This video wall processor accepts a single HDMI input at resolutions up to 4K Ultra HD (3840x2160) at 60Hz, then processes and distributes the signal across four HDMI outputs, each delivering 1080p Full HD resolution. The 2x2 video wall mode spans the source image across all four displays to create a single large canvas, while the splitter mode mirrors the same content identically on each screen.
Control and integration are facilitated through RS-232 serial and Ethernet (RJ-45) ports, enabling remote management, scheduling, and automation via third-party control systems. A USB port provides additional configuration options. The device supports EDID emulation to maintain consistent communication with source and display equipment, preventing handshake issues and simplifying installation.
This section brings together practical product details such as HDMI In, HDMI Out, Network (RJ-45), Input Voltage, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
