User-replaceable VFC cards are accessories to d3 Technologies’ flagship d3 4x4pro server. These cards enable users to mix and swap video output signals directly from one server, allowing them to drive up to 16HD outputs as DVI or SDI (1,080p) or 4x4K DP1.2. This means large, multi-projector shows can now be delivered with fewer machines, no downstream splitters, and practically no signal latency. The output cards are an industry first, according to the developer: no other media server on the market offers the ability to gracefully transition from HD to 4K as 4K proliferates. As new signal standards gain popularity, the company plans to release new output cards to handle them. d3technologies.com
