Four-input HDMI multiviewer

This LUOM switch accepts four HDMI 1.4 sources and sends a single HDMI 1.4 signal to one display. It shows all four inputs simultaneously in quad, picture-in-picture or full-screen layouts at up to 3840 x 2160 resolution. KVM hot-key and IR remote control let you change the active source without leaving your keyboard. The unit ships with a USB power adapter and four USB data cables for keyboard and mouse passthrough.

Check your sources and display

Each connected device must output HDMI 1.4 and support HDCP 1.4 for protected content. The monitor or projector must accept 3840 x 2160 at 30 Hz or 1080 at 60 Hz through its HDMI 1.4 input. Verify that your keyboard and mouse use standard USB connectors so the supplied data cables can link them to the switch. No external power beyond the included adapter is required.

Replaces separate switch and KVM units

This multiviewer replaces a standalone HDMI switch plus a separate USB KVM when you need simultaneous viewing of four computers, cameras or consoles on one screen. The jump is worth it if you currently swap cables or run two boxes to monitor security feeds, workstations or gaming systems. It does not suit setups that require 4K at 60 Hz, HDMI 2.0 bandwidth or more than four inputs.

Questions about this item

Does the package include the HDMI cables I need to connect four sources and one display?

The box contains the switch, a USB power adapter, four USB data cables, a remote control and a manual; HDMI cables for the four inputs and the single output are not supplied and must be purchased separately.

Which resolution and refresh-rate combination should I pick if my monitor only accepts 4K at 30 Hz?

The switch supports up to 3840 x 2160 at 30 Hz and 1080p at 60 Hz; choose the 4K 30 Hz setting to match a display limited to that refresh rate.

What does the 4K 30 Hz headline figure mean when I actually plug four computers into this switch?

Each of the four HDMI 1.4 inputs can carry 3840 x 2160 at 30 Hz, and the single output mirrors that resolution and refresh rate whether you view one source full-screen or use any of the five multi-view layouts.
