Two-Port DisplayPort 1.4 KVM Switch

The BUCIER KVM switch lets you share one DisplayPort monitor between two computers or send a single computer signal to two displays. Manual push-button switching changes the active source instantly with LED indication. External power is required for operation. It suits home-office workers and gamers who need to toggle between a desktop and a laptop or between a PC and a console. Buyers who need simultaneous multi-monitor output should look elsewhere.

32.4 Gbps Bandwidth for 8K30 and 4K120

The single specification that decides compatibility is the 32.4 Gbps maximum throughput of the DisplayPort 1.4 link. This bandwidth carries 8K resolution at 30 Hz, 4K at 120 Hz and 1080p at 240 Hz without compression. Standard DisplayPort 1.4 cables must be used to reach these rates. If your source or display demands higher bandwidth than 32.4 Gbps, this switch will not pass the signal.

Stable Switching Under Continuous Load

Under sustained gaming or workstation loads the switch maintains a steady link because it is a passive bidirectional signal router with no active processing. The external power adapter keeps the internal transceiver powered during long sessions, preventing handshake drops when sources change power states. Manual selection avoids automatic switching glitches that can interrupt full-screen applications. The unit runs silently and requires no driver installation.

Questions about this item

What does 8K at 30 Hz mean for my monitor setup?

The switch can pass an 8K signal at 30 frames per second to a single display, so you get full 8K resolution but at a lower refresh rate suited to video or productivity rather than high-speed gaming.

What does the DisplayPort 1.4 interface with 32.4 Gbps bandwidth cap in practice?

It limits the maximum throughput to 32.4 Gbps, which enables 8K at 30 Hz, 4K at 120 Hz, or 1080p at 240 Hz, provided you use standard DP 1.4 cables.

What physical connections and power does the unit need to fit on my desk?

It requires three DisplayPort cables — two for sources or displays and one for the shared port — plus an external power adapter to operate the manual select button and indicator lights.
