Designing systems capable of distributing 4K Ultra High Definition media requires support for the content of today, and headroom for the content of tomorrow. The Gefen EXT-UHD600-12 splitter distributes signal from one 4K source, and distributes it to up to two 4K displays or video zones. The splitter features a low profile, compact, and surface-mountable enclosure that can fit in tight places. It also accommodates Gefen locking HDMI cables for secure connections.
Gefen’s Ultra HD 600MHz Series of splitters take HDMI 2.0 to its highest specification of 4K 60 Hz at 4:4:4 chroma subsampling, along with HDR (High Dynamic Range) support. They go beyond the requirements of typical 4K systems, delivering stunning Ultra HD and DCI/Cinema picture up to 4096 x 2160 pixels at 60 frames per second without subsampling color. This ensures that the scene shown on the display is every bit as brilliant as the picture that the camera captured. HDR lets every subtle nuanced gradation of each pixel play out across the screen in immersive clarity. Gefen's Ultra HD 600MHz Series creates a seamless bridge between the digital media of yesterday, today, and tomorrow.
