Dual-Monitor KVM for Two PCs

This BUCIER KVM-504B switch lets one keyboard, mouse and two monitors control two computers. Each PC must provide both an HDMI and a DisplayPort output; the switch does not convert between them. It suits professionals and gamers who need a single workstation for dual systems. Extended and mirror display modes are supported.

HDMI 2.1 and DP 1.4 Bandwidth Limits

The HDMI path reaches 8K at 60 Hz while the DisplayPort path reaches 4K at 120 Hz. Both monitors, cables and source GPUs must match the target resolution and refresh rate or flickering will appear. No higher resolutions or refresh rates are possible through this unit. USB 3.0 peripheral ports operate at 5 Gbps and are backward compatible.

Physical Button and Desktop Controller

Switching is done only by the front-panel push button or the wired desktop controller; no keyboard hotkeys exist. The included 5 V power adapter is required for stable operation. Connect USB devices directly without adapters to avoid recognition problems. The package supplies two USB 3.0 cables for the PC links.

Questions about this item

Should I pick the HDMI 8K 60 Hz or the DisplayPort 4K 120 Hz path for my monitors?

Use HDMI 2.1 for 8K 60 Hz or DisplayPort 1.4 for 4K 120 Hz; each computer must provide both an HDMI and a DisplayPort output, and cables must match the chosen resolution.

What does the 8K 60 Hz rating mean once the switch is connected to my PC and monitor?

It means the HDMI 2.1 link can pass 8K at 60 Hz if the source, monitor and cable all support that mode; otherwise the link falls back to a lower resolution or refresh rate.

Which USB standard do the four hub ports use and what speed does it cap at?

The hub runs on USB 3.0 at 5 Gbps and is backward compatible with USB 2.0 and 1.1 devices; connect peripherals directly without adapters.
