LUOM 4x1 HDMI KVM Multiviewer

This LUOM HDMI KVM Multiviewer Switch accepts four HDMI 1.4 inputs and delivers a single HDMI 1.4 output at up to 4K@30Hz or 1080p@60Hz. It is built for engineers, exhibition halls, video meetings and surveillance rooms that need to view or control multiple sources on one display.

Five viewing modes and USB KVM control

The unit offers five screen layouts, showing all four inputs at once or any single source full-screen. Four USB 2.0 ports and hot-key switching let a single keyboard and mouse control the connected computers without extra cables or software.

Replaces separate switchers and KVM boxes

It consolidates a quad multiviewer, a seamless HDMI switch and a USB KVM into one device, removing the need for multiple boxes and frequent cable changes. The jump is worth it when a project demands simultaneous monitoring and instant source switching from one workstation.
