Product overview A compact 3x3 video wall controller that splits one video input into nine outputs for building a large, synchronized display. Housed in a metal and iron case with a black finish, the controller supports 4K input and output at 30Hz and offers multiple splicing modes, rotation and edge masking for clean, professional presentations. Key benefits Simplifies multiscreen installations by converting a single source into nine synchronized HD outputs, reducing system complexity and cabling. Preserves image quality with 4K (3840 x 2160) input and output support at 30Hz, plus a stereo sound port for external audio devices. Flexible layout options and cascade support let you scale the video wall to larger formats without changing source equipment. Built from durable metal and iron for reliable, longterm use in commercial and public environments. Main features Item type: 3x3 Video Wall Controller Material and color: Metal, Iron; black finish Power: 12V adapter included Remote control: Remote included; requires 2 x AAA batteries not included Inputs and outputs: 1 input, 9 outputs (9way) Resolution: Input and output support up to 4K (3840 x 2160) at 30Hz and below Audio: Stereo sound port for external speakers or audio devices Cascade support: Up to 2 units cascade for expanded configurations Splicing modes: 16 modes total Single unit modes: 1x1, 1x2, 1x3, 1x4, 2x1, 2x2, 2x3, 2x4, 3x1, 3x2, 3x3, 4x1, 4x2 Dual unit (2 units cascaded) modes: 3x4, 4x3, 4x4 Image adjustments: 180 degree rotation, inverted image rotation, and edge masking to minimize bezels and reduce visible borders Operation: Plug and play; mode switching via remote control or front panel buttons How it helps solve common problems Eliminates the need for multiple source devices by routing a single signal to multiple screens. Reduces visible seams and alignment issues with edge masking and rotation tools, improving visual continuity across tiled displays. Supports scalable installations without complex reconfiguration through cascade support and multiple splicing modes. Maintains image fidelity at resolution while allowing external audio integration for immersive presentations. Use scenarios Retail digital signage: Create a large storefront display from nine panels to show resolution product imagery and promotional content with synchronized playback. Control rooms and operations centers: Combine multiple monitors into a single logical screen for map visualization, monitoring dashboards, or situational awareness displays. Events and exhibitions: Build a 3x3 or larger video wall for presentations, trade show booths, or live event backdrops with easy mode switching and audio output for onsite sound. Package contents 1 x Video Wall Controller 1 x Remote Control 1 x Adapter 1 x User Manual Installation and operation Plug and play setup. For detailed wiring, mode configuration, and advanced settings, follow the included user manual. Use the remote control or front panel buttons to switch splicing modes and adjust rotation or edge masking. For cascaded setups, connect up to two units to enable 3x4, 4x3, or 4x4 layouts. Compatibility and recommendations Designed to accept common HDMI video sources that output up to 4K at 30Hz and below. Recommend using frameless or thinbezel displays to maximize viewing continuity and minimize visible borders. Technical notes Requires 12V power via the supplied adapter. Remote control requires 2 x AAA batteries, not included. Supports definition splitting and synchronization across nine displays; cascade two units for larger configurations.
