3x3 HDMI Video Wall Controller Overview This 3x3 HDMI video wall controller distributes a single HDMI or DVI input signal to nine HD displays simultaneously, creating a single large dynamic video wall or digital signage display. It is designed for reliable multiscreen presentation and control in commercial and professional environments. For results, use professional video wall displays rather than consumer TVs. Key benefits Create a unified 3x3 video wall from one source for monitoring, presentation, or advertising. Maintain full 1080p at 60 Hz output across all screens for smooth motion and consistent image quality. Flexible layout and easy switching of display modes with included IR remote or RS232 control. Edge mask and 180degree rotation options reduce visible bezel impact for a cleaner multiscreen image. Simple integration with existing HDMI and DVI source devices and professional video wall displays. Main features Input and output Accepts one HDMI or DVI input device, supporting resolutions up to 4K at 30 Hz on input. Provides nine HDMI outputs with maximum output resolution of 1920x1080 at 60 Hz. Independent SPDIF audio output for soundbar, speakers, or amplifier connections. Resolution and compatibility Compliant with HDCP 1.4 and HDMI 1.4 standards. Designed for use with security cameras, DVD and BluRay players, TV boxes, streaming sticks, game consoles, computers, satellite receivers, and other HDMI sources. Recommended to set each screen to 1080p to ensure consistent operation and image quality. Splicing and layout modes Supports up to 12 splicing modes, covering common horizontal and vertical arrangements: Horizontal modes: 2x1, 3x1, 4x1, 3x2, 4x2 Vertical modes: 1x2, 1x3, 1x4, 2x3, 2x4 Composition modes: 1x1, 2x2, 3x3 Switch modes remotely with the IR remote or via RS232 for automated control systems. Rotation and bezel management 180degree rotation available for HDMI outputs 1 and 2 to orient thin bezel edges toward the center and reduce visible center bezel thickness. Edge mask function helps minimize bezel visibility and improve the perceived continuity of the image. Note: 180degree rotation applies to all multiscreen modes except 1x1 and requires output resolution not exceeding 1080p at 60 Hz. Control and installation Mode switching via IR remote or RS232 command set for control room or integrated control systems. Simple wiring: one HDMI or DVI source to the controller, nine HDMI runs to displays. Ensure all displays use the same resolution and refresh rate for stable operation. Practical applications Control rooms and monitoring centers: Combine multiple camera feeds or data sources into a single large display for situational awareness. Retail and digital signage: Create eyecatching promotional walls in stores and malls with synchronized content across nine panels. Conference rooms and public spaces: Present largeformat video, presentations, or broadcast content across a unified multiscreen canvas. Technical reminders Use professional video wall panels for edge alignment and visual quality rather than consumer televisions. Set all displays to 1920x1080 at 60 Hz before operation to avoid resolution conflicts. Input sources can support up to 4K at 30 Hz, but outputs are limited to 1080p at 60 Hz. This 3x3 HDMI video wall controller provides flexible splicing modes, reliable 1080p performance, and multiple control options for professional multiscreen installations.
