Two-computer dual-monitor KVM switch

This KVM switch connects two computers to one keyboard, one mouse and two displays. It switches both video channels simultaneously so the operator moves between workstations without changing peripherals. The unit is intended for desk setups that need a single control point for a laptop and a desktop or a console.

Steady 4K 60 Hz operation with adaptive EDID

The switch maintains HDMI 2.0 bandwidth continuously, delivering 4K at 60 Hz without frame drops during long sessions. Adaptive EDID keeps the correct resolution and timing on each monitor after every switch. Lower resolutions such as 1080p at 144 Hz or 120 Hz are also sustained without handshake loss.

USB 3.0 sharing and 3.5 mm audio extraction

A front USB 3.0 port lets a scanner, flash drive, 3D printer or webcam stay plugged in while the active computer changes. The built-in DAC feeds stereo sound to a 3.5 mm headset jack, removing the need for separate audio cables. HDCP 2.2 compliance ensures protected content plays on both outputs.

Questions about this item

Does the BUCIER 2 Port Dual Monitor KVM Switch run hot or draw much power when both PCs are active all day?

The unit is a passive HDMI 2.0 switch with no fan, so it stays cool and draws only the small amount needed for the internal DAC and USB 3.0 hub logic.

What cables must I already have to connect two computers and two monitors to this KVM?

You need four HDMI 2.0 cables — two from each computer to the switch inputs and two from the switch outputs to the monitors — plus two USB-A to USB-B cables for keyboard and mouse sharing.

Will my older 1080P monitors at 120Hz or 144Hz work correctly through this switch?

Yes, the switch supports 1080P at 120Hz and 144Hz as well as lower resolutions, and its adaptive EDID handles handshake with older displays automatically.
