Product overview A compact 2x2 video wall controller that splits a single definition source into four synchronized HDMI outputs, creating a single large dynamic display from four HDMI screens. Designed for easy setup and reliable operation in commercial and professional display installations. Key benefits Create a seamless large screen: Divide one HDMI, DVI, or USBC source into four HDMI outputs to build a 2x2 video wall for presentations, signage, or monitoring. resolution support: Handle up to 3840 x 2160 at 30 Hz input and output 4K at 30 Hz or 1920 x 1080 at 60 Hz for clear, detailed images. Flexible orientation and layouts: Continuous clockwise rotation available in 90, 180, and 270 degrees and multiple splicing modes let you adapt the display to different content and installation directions. Note: when rotating, both input and output cannot exceed 1920 x 1080 at 60 Hz. Robust, lowlatency design: Metal enclosure with good heat dissipation, antiinterference and corrosion resistance, plus goldplated interfaces to reduce signal loss and maintain stable transmission without visible delay. Simple control and installation: Plug and play operation requires no drivers. Adjust settings using the supplied IR remote or the builtin front panel buttons.
