Four-input HDMI multiviewer

The LUOM HDMI 4x1 Quad KVM Multiviewer Switch accepts four HDMI 1.4 sources and sends a combined or single image to one HDMI 1.4 display. It supports five viewing modes including full-screen and quad-split layouts. Control is available via front-panel buttons, the included IR remote or keyboard hotkeys. The unit is powered by the supplied USB adapter and cables.

4K at 30 Hz maximum resolution

Video throughput tops out at 3840 x 2160 at 30 Hz, with 1080p at 60 Hz also supported. HDMI 1.4b and HDCP 1.4 compliance allows connection of laptops, security cameras or gaming consoles. Sources requiring 4K at 60 Hz or higher refresh rates will not display correctly through this switch.

USB-powered, plug-and-play setup

Connect the four input cables, the single output cable and the USB power adapter; no driver installation is needed. The main installation issue is neglecting the power adapter, which causes signal loss or unstable switching. Ensure every source device is powered on before selecting its channel to avoid a blank screen.

Questions about this item

What does the 4K@30Hz rating mean when I connect four sources to one display?

The switch can output up to 3840 x 2160 at 30 Hz, so all four inputs appear together in multiview or one fills the screen at that refresh rate.

How does the HDMI 1.4 interface limit what I can send through the switch?

HDMI 1.4 caps the link at 4K@30Hz and 1080p@60Hz with HDCP 1.4, so higher refresh rates or newer copy protection are not supported.

What does the unit need to fit on a desk or rack?

It ships with a USB power adapter and four USB data cables; the box itself has four HDMI inputs and one HDMI output for a compact desktop footprint.
