What this KVM switch does

The BZBGEAR BG-UHD-KVM21A lets you operate two computers from one monitor, keyboard, mouse and audio devices. It accepts two HDMI 1.4 inputs and provides one HDMI 1.4 output with support up to 4K at 30 Hz. Three front USB 2.0 ports share peripherals between both systems, while 3.5 mm jacks switch microphone and headphone connections.

Who this suits and who should look elsewhere

It suits office workers, developers and support staff who need to toggle between two PCs running Windows, macOS or Linux without leaving their desk. Buyers who need switching for more than two computers, or who require USB 3.x speeds for storage devices, should consider a different switch.

The specification that decides fit

The HDMI 1.4 interface caps video at 4K 30 Hz, so the switch fits workflows that stay within that bandwidth. If your display or source needs higher refresh rates or deeper colour at 4K, this model will not satisfy that requirement.

Questions about this item

Does the BG-UHD-KVM21A generate noticeable heat or fan noise when left on all day?

The BG-UHD-KVM21A has no fan and draws minimal power, so it runs silently and stays cool during continuous operation.

Which cables and peripherals must I already own to use the BG-UHD-KVM21A?

You need two HDMI 1.4 cables, two USB 2.0 Type-B cables, a keyboard, a mouse, and a monitor with an HDMI 1.4 input.

Will the BG-UHD-KVM21A work with an older PC that only outputs 1080p over HDMI 1.4?

Yes, the switch passes any HDMI 1.4 signal up to 4K@30Hz, so a 1080p source works without extra setup.
