Video Wall Controller 2x2 is a professional video wall processor that splits a single HDMI full HD signal into four synchronized outputs for seamless splicing across four displays. It is designed to build a single large dynamic image from four HDMI displays while keeping color fidelity and simple control. Key benefits Create large, contiguous displays from one source: divides a complete HDMI 1080P image into four blocks and assigns each block to a separate display for a combined 2x2 video wall. Full HD performance and color accuracy: supports 1080P input and output with RGB 4:4:4 output for consistent color reproduction across all screens. Flexible installation and layouts: multiple splicing modes adapt to different display arrangements, letting you use 2x2, 1x1, 1x2, 1x3, 1x4, 2x1, 3x1, or 4x1 configurations. Easy control and orientation: local frontpanel buttons, IR remote, and RS232 control provide multiple management options; 180 degree flip supports rotated or inverted displays. Simple connectivity: accepts HDMI and DVI input and provides four HDMI outputs, all supporting 1920*1080P/60Hz. Features and compatibility Input: one HDMI or DVI input, up to 1920*1080P/60Hz. Output: four HDMI outputs, each up to 1920*1080P/60Hz. Automatic 2x2 splicing function for quick setup of a 4screen wall. Output color support: RGB 4:4:4. Control interfaces: RS232, frontpanel buttons, and IR remote. Multiple splicing modes: 2x2, 1x1, 1x2, 1x3, 1x4, 2x1, 3x1, 4x1. 180 degree flip support for display orientation adjustments. Practical applications Control rooms and monitoring centers: build a compact 2x2 wall to monitor multiple video feeds or enlarge a single feed for detailed observation. Retail and digital signage: create a single impact display from four screens to show promotions, product content, and dynamic advertising. Conference rooms and events: combine four displays into one full HD presentation screen for meetings, trade shows, or live events.
