Gefen GF-HDK18G-VIP-RX 4K HDMI KVM Over IP Receiver Extender

Gefen GF-HDK18G-VIP-RX 4K HDMI KVM Over IP Receiver

The Gefen GF-HDK18G-VIP-RX 4K HDMI KVM over IP receiver connects a remote display and USB peripherals to networked sources. It delivers HDMI output up to 4K 60Hz with 4:4:4 color sampling. A separately sold compatible sender completes the system, extending keyboard, video, and mouse access through a Gigabit network.

This Gen3 endpoint suits control rooms, classrooms, meeting spaces, and digital signage installations that require distributed source access. Two USB ports accommodate local peripherals, while independent routing lets installers assign video, audio, and control separately. For remote workstation access over Ethernet or a multi-display AV distribution system, USB roaming and keyboard hotkeys simplify source selection.

An integrated scaler adapts output resolution, and video wall controls support layouts with bezel compensation. HDR, or high dynamic range, compatibility includes HDR10, HDR10+, and Dolby Vision. Analog audio extraction connects external sound systems, while optical audio return carries display audio toward the source location. Network deployments require a managed Gigabit switch with IGMP Snooping and jumbo frames of at least 8K. Power over Ethernet or the included adapter powers the receiver.
