This Video Wall Controller is designed to capture, convert, route and distribute all video signal formats to a video wall. It features HDMI and USB-C input with resolution up to 4K at 60 Hz and four HDMI outputs to create eight video wall splicing modes to be stretched either horizontally or vertically; 1x1, 2x1, 3x1, 4x1, 1x2, 1x3, 1x4 and 2x2. You can set display modes via front-panel buttons, the included IR remote or RS232 commands. The B119-1X4-4K6-VW supports Ultra HD 4K resolutions at 60 Hz with LPCM, Dolby Digital/Plus/EX and DTS audio. It supports HDR (High Dynamic Range), providing a wide range of vibrant colors with richer contrast, brighter whites and deeper blacks that pop on your 4K display. HDCP 2.2 encryption allows you to stream 4K content with no loss in resolution. This switch also supports uncompressed 4:4:4 chroma subsampling for top-level PC gaming or using your HDTV as a PC monitor. The unit works right out of the box with no software required. Mounting hardware is included for installing the units on a wall, under a desk or in a 19" rack. Connect a 4K source device to either the HDMI or USB-C input and up to four 4K displays to the HDMI outputs with user-supplied cables. The external power supply comes with four international plug adapters to ensure an AC connection anywhere.
