Get Started


This conference room presentation switcher is a great option for users looking to efficiently manage up to 4 computers from a single workstation using one keyboard, one mouse, and one monitor. This 4X1 HDMI 2.0 KVM switch can support video resolutions up to 4Kx2K@60Hz (4:4:4). The switcher works with multiple operating systems, ensuring maximum compatibility with connected devices.

The BG-UHD-KVM41 is a brilliant option for conference room systems when paired with the optional BG-SC-GRHU table grommets. These grommets can be installed in a tabletop and provide USB and HDMI connections along with local source selection and video mute buttons. The grommets can be purchased separately or as a bundle with the BG-UHD-KVM41-KIT.

Connectivity and Control

This KVM switch has four HDMI video inputs and one HDMI output, allowing you to connect multiple computers and switch between them on one display. There are four type-B USB 3.0 host ports as well and three type-A ports for KVM management with peripherals like a mouse and keyboard. This will enable you to control all four connected computers with one set of peripherals.

The BG-UHD-KVM41 supports Windows, MacOS, and Linux devices. A 3.5 mm stereo audio output is also included for audio de-embedding. Users can easily control the device via the front panel buttons, RS232 commands, or with the recessed table grommets.
