Four-computer HDMI KVM

This 4-port HDMI 2.1 KVM switch lets four computers share a single monitor, keyboard, mouse and up to four USB 3.0 peripherals. A wired remote and front-panel buttons both change the active system. LED indicators show which computer is selected. The unit includes a 12 V power adapter for stable operation with high-power USB devices.

8K60 and 4K144 video headroom

The switch passes video up to 8K at 60 Hz or 4K at 144 Hz when an 8K-rated HDMI cable is used, and remains compatible with 4K at 60 Hz and 1080p sources. Simulation EDID can be toggled on or off by holding the PC1 button for three seconds, preventing window rearrangement during switching. Final resolution depends on the graphics card, cables and monitor.

Desktop build with audio and remote

The enclosure measures 5.31 by 2.56 by 1.26 inches and weighs 330 g, fitting easily on a desk. Each computer connects with one HDMI and one USB 3.0 cable; the monitor connects via a single HDMI output. A 3.5 mm jack routes headphone or microphone audio separately from the HDMI audio path. Four USB 3.0 ports support 5 Gbps transfers and accept wireless keyboards, mice, printers and other peripherals.

Questions about this item

Will the 8401BA pass 8K@60Hz from an older GPU through HDMI 2.1?

The switch supports 8K@60Hz via its HDMI 2.1 ports, but the final resolution depends on your graphics card and cables; use certified 8K HDMI cables for best results.

How do I confirm the EDID simulation is active after connecting four PCs?

Press and hold the PC1 button for three seconds until the EDID indicator blinks constantly; this shows the simulation is on and prevents window rearrangement when switching.

Does the box include the four HDMI cables needed to link each computer?

The package contains the KVM unit, four USB 3.0 cables, a 1.5 m wired remote and a 12 V power adapter; HDMI cables for the four inputs and the monitor output must be purchased separately.
