VDS-1x HDMI UHD 18Gbps Downscaler


Video distribution deployments with mixed resolution displays can be challenging. For example, an installation with a legacy 1080p TV in one room and a fantastic new 4K HDR TV in another room, and they both need to access the same ultra-high definition content. In cases like this, the simple solution is the VDS-1x HDMI downscaler.

The VDS-1x converts 4K video to 1080p in real time with no latency or tearing. Engineered to support even the highest resolution UHD content, the downscaler also offers an optical audio output, and a low profile design, small enough to fit behind any TV.
