Deliver a unified 4K canvas across four displays with the Gefen EXT-UHD600A-VWC-14. This 1x4 video wall controller accepts a single HDMI source at 4K 60 Hz 4:4:4 and processes it for signage and presentation environments where image consistency matters. HDCP 2.2 and 1.4 support helps maintain compatibility with protected content, while the 600 MHz TMDS clock preserves signal integrity for demanding installations. Audio de-embedding adds flexibility for systems that route sound separately from the video wall. That matters in venues where the displays and the audio path are managed by different components, or where the controller must feed an external amplifier or DSP. The result is a cleaner deployment with fewer conversion points and less compromise at the source. Designed for retail outlets, clubs, trade shows, control centers, and building lobbies, this controller is built for environments where the display wall is part of the experience. It gives integrators a focused tool for turning one premium 4K source into a coordinated multi-screen presentation without sacrificing detail or timing.
