Four-Port HDMI KVM Multi-Viewer

This KVM switch connects four HDMI sources to one display so a single keyboard and mouse control every system. It suits home offices, streaming setups and multi-computer workstations that need simultaneous viewing. Users who require more than four inputs or resolutions above 4K@30Hz will need a different solution.

Passive Operation

The unit draws power from the connected HDMI sources and has no internal fans, so it adds no audible noise or measurable heat to the desk. Power consumption scales with the number of active inputs but remains negligible for typical USB-powered ports. No external power adapter is included or required.

Five Viewing Modes and Four Switching Methods

The switch offers single, dual and quad split layouts plus picture-in-picture arrangements selectable by front-panel buttons, IR remote, hotkey combinations or mouse gestures. Hotkeys also toggle audio routing, resolution presets and full-screen or quad modes without software installation. The remote ships without batteries.

Questions about this item

How do I connect four computers and one monitor to this KVM switch?

Connect each computer to one of the four HDMI inputs using HDMI cables, then connect your monitor to the single HDMI output. Plug a USB keyboard and mouse into the dedicated console ports on the switch.

What ongoing maintenance does the IR remote require?

The IR remote is supplied without batteries, so you will need to insert two AAA batteries before first use and replace them when the remote range decreases.

At what refresh rate does the 4K output become the limiting factor during extended sessions?

The maximum supported resolution is 3840x2160 at 30 Hz, so sustained 4K work or playback is capped at that refresh rate regardless of source capability.
