8K@60Hz HDMI KVM Switch

The BUCIER KM401F-USB3.0-8K-H connects four HDMI-equipped computers to a single display and shared USB peripherals. It supports resolutions up to 8K@60Hz and 4K@120Hz, with backward compatibility for 1080p@240Hz and 1440p@120Hz. Four USB 3.0 ports provide up to 5 Gbps data transfer for drives, printers and input devices. A 12 V 1 A power adapter ensures stable operation.

Suits multi-system desks; not for hotkey users

This switch targets users who need to operate Windows, macOS or Linux machines from one monitor, keyboard and mouse setup. Front-panel buttons and a wired desktop controller give two hardware switching methods with LED status indication. The unit does not support hotkey switching, so buyers who rely on keyboard shortcuts to change ports should look elsewhere. Each computer requires its own HDMI and USB-A connection to function.

8K@60Hz over HDMI 2.1 decides fit

The single specification that determines compatibility is the 8K@60Hz HDMI 2.1 video path. Both the source graphics cards and the monitor must support this signalling rate, and a certified ultra-high-speed HDMI cable is needed to achieve the advertised resolution. Without 8K-capable endpoints and cabling, the switch will fall back to lower supported modes such as 4K@60Hz or 1080p@240Hz.

Questions about this item

What cables and accessories come with the BUCIER KM401F-USB3.0-8K-H and what must I supply?

The package includes four USB cables and a desktop controller. You must provide HDMI cables for each computer and the monitor, plus a 12 V 1 A power adapter which is required for stable operation.

Should I choose this 8K@60 Hz model or a lower-resolution KVM for my 4K@120 Hz monitor?

This switch supports 8K@60 Hz, 4K@120 Hz, 4K@60 Hz, 4K@30 Hz, 2560×1440@120 Hz and 1920×1080@240 Hz, so it covers your 4K@120 Hz display and leaves headroom for future upgrades.

Will I actually see 8K@60 Hz on screen once everything is connected?

You will get 8K@60 Hz only if every computer's graphics card, the monitor and the HDMI cables all support that resolution; otherwise the switch falls back to the highest common mode such as 4K@120 Hz or 4K@60 Hz.
