Gefen EXT-UHD600A-12-DS – 4K Ultra HD 600 MHz 1:2 HDMI Scaler with EDID Detective and Audio De-Embedder

The Gefen EXT-UHD600A-12-DS is a compact, high-performance solution for splitting and scaling full-bandwidth HDMI 2.0 audio and video signals with HDR. It enables the simultaneous use of two displays—either two 4K 600 MHz displays or one in 4K and one in 1080p Full HD—thanks to its dual configurable scalers.

With a bandwidth of 18.2 Gbps and a TMDS clock rate of 600 MHz, this scaler meets the highest HDMI 2.0 specification. Its integrated optical and analog audio outputs allow the audio signal to be de-embedded for connection to external amplifiers and sound systems—ideal for bars, restaurants, venues, and offices.

The built-in EDID Detective ensures reliable compatibility with a wide range of sources and displays. Flexible scaling lets you downscale one HDMI output from 4K to 1080p while upscaling the other from HD to 4K.
