4x2 HDMI KVM matrix for multi-PC control

The BUCIER 4x2 HDMI KVM switch matrix connects four HDMI sources to two independent displays. Two keyboard and mouse sets control all four connected computers. It suits operators who manage multiple workstations from a single desk in offices, control rooms or training spaces.

Installation uses front buttons.

Three switching modes let users change sources by front-panel button, infrared remote or keyboard hotkey sequence. HDMI inputs accept cables up to 15 metres at 4K 30 Hz or 5 metres at 4K 60 Hz. USB 2.0 cables are limited to the supplied 2 metre length. The unit draws up to 800 mA from the included 5 V 1.5 A adapter.

Sustained 4K 60 Hz operation within cable limits

The matrix maintains 3840×2160 at 60 Hz through its 600 MHz bandwidth and 3×6 Gbps links. Deep-colour 8, 10 or 12 bit video passes continuously. Audio extracts simultaneously over optical and 3.5 mm ports in LPCM, Dolby or DTS 5.1. A built-in down-scaler converts 4K input to 2K output when displays require it.

Questions about this item

How can I confirm the 3840×2160/60Hz signal is passing correctly after connecting four sources and two displays?

Power the unit with the included DC5V/1.5A adapter, select each input via the front button or IR remote, and verify both monitors show a stable 4K 60 Hz image without flicker or downscale to 2K.

What cables and accessories ship in the box, and what must I provide separately?

The package includes the matrix, a DC5V/1.5A power adapter, an IR remote, and four 2 m USB 2.0 A-to-B cables; you must supply four HDMI 2.0 cables (≤5 m for 4K 60 Hz) and two HDMI display cables.

Should I choose a different model if I only have two computers but need dual-monitor extended desktop?

This 4×2 matrix is designed for four sources and two displays; if you only have two computers, a simpler 2-port dual-monitor KVM would be more cost-effective.
