What this switch does

This LUOM HDMI KVM multiviewer connects four HDMI 1.4 sources to one display. It shows all four inputs at once in split-screen layouts or switches cleanly to a single source at up to 4K@30Hz or 1080p@60Hz. Control is by front button, IR remote or keyboard hotkeys.

Who it suits and who it does not

The unit fits security desks, meeting rooms or any desk where four PCs, consoles or STBs share one monitor. Buyers who need 4K@60Hz output, HDMI 2.0 bandwidth or more than four inputs should look elsewhere.

Installation notes

Power the box from the included USB adapter, plug the four source cables and one display cable, then choose a view mode with the remote or Ctrl+Ctrl hotkeys. A common issue is forgetting to supply USB power, which leaves the switch inactive.

Questions about this item

What display and cables do I need to use the 4K@30Hz output?

Connect the HDMI 1.4 output to a monitor or TV that accepts 3840 x 2160 at 30 Hz using a standard HDMI cable.

Can I keep my 1080p sources connected while running the switch at 4K@30Hz?

Yes, the switch supports mixed resolutions up to 1080p at 60 Hz and 4K at 30 Hz on its four HDMI 1.4 inputs simultaneously.

How can I confirm the multiviewer is showing all four inputs correctly after setup?

Cycle through the five display modes with the IR remote or front button; each mode should show the expected full-screen or split-screen layout without signal loss.
