Two-Computer HDMI KVM Switch

This BUCIER KVM switch lets two computers share one HDMI monitor and three USB 2.0 peripherals. It supports Windows, Mac OS, Linux, UNIX and DOS without extra software. Two 2-in-1 KVM cables and a wired remote button are included. No external power supply is required for operation.

Sustained 30Hz 4K Output

The HDMI output delivers 3840x2160 resolution at 30Hz continuously during extended sessions. Switching between the two connected PCs via the panel button or wired remote does not interrupt the video signal. USB 2.0 peripheral sharing remains stable across both computers without re-enumeration delays. The fanless design maintains silent operation under constant load.

HDMI and USB 2.0 Interface Limits

Maximum video bandwidth caps at 3840x2160 at 30Hz, so higher refresh rates are not supported. USB ports operate at 2.0 speeds only, limiting throughput for storage or high-speed devices. Only two host computers can be connected simultaneously. The wired remote button requires a direct cable run to the switch unit.

Questions about this item

Does the BUCIER KVM switch generate noticeable heat or fan noise when left running all day?

The BUCIER KVM switch operates without an external power adapter and has no fan, so it produces no audible noise and negligible heat during continuous use.

What cables or peripherals must I already own to connect two computers to this BUCIER KVM switch?

Two 2-in-1 KVM cables (HDMI + USB) are included in the box, so you only need to provide the keyboard, mouse and any USB 2.0 devices you want to share.

Will my older 1080p monitor work correctly with the BUCIER switch's 3840x2160@30Hz output?

Yes, the HDMI output down-scales automatically, so a 1080p or 1440p display will show a proper image at its native resolution.
