The DKM FX Modular KVM Extender Interface Card extends visually lossless, high-resolution DisplayPort signals over fiber cable. It also features two USB HID ports so you can easily connect your keyboards, mice, and other devices. You can use the extender card with the DKM FX Chassis for matrix switching or as a point-to-point KVM extender. The DKM FX Extender Card supports 4K resolutions (4096 x 2160 and 3840 x 2160) in single-head mode and up to 1920 x 1200 video in dual-head mode. Audio is directly reproduced by any connected displays with integrated speakers. The stereo signal can also be extracted and output separately.
