BZBGear BG-UHD-KVM21A 2-Port 4K KVM Switch

The BG-UHD-KVM21A lets one workstation drive two computers. Each of the two rear positions has an HDMI 2.0 input and a USB 2.0 Type-B host port; the front carries three USB 2.0 ports for a keyboard, a mouse and one spare device.

Input is accepted up to 4K60 and output runs to 4K30, which suits the desk with a Windows machine and a Mac on the same screen. 3.5 mm jacks handle a microphone and headphones or speakers, switching with the video. The metal case is 156 x 69 x 25 mm and runs from a universal mains supply.
