4-Port HDMI KVM Switch for Four Computers

This HDMI 2.0 KVM switch lets a single monitor, keyboard and mouse control up to four HDMI-equipped hosts such as PCs, laptops, game consoles or servers. It supports mechanical and wireless input devices and adds a USB 2.0 port for sharing peripherals like flash drives, printers or webcams between the connected systems.

Compact Metal Chassis with Front-Panel Buttons

The unit measures 11.0 x 6.0 x 3.3 cm and uses HDMI-A ports for video plus USB-B inputs and a USB-A output for peripheral sharing. A dedicated switch cable provides tactile source selection, while the integrated EDID reader stores each display's parameters so resolution handshake remains consistent whenever you swap between the four connected computers.

Passive Cooling Draws Maximum 2 Watts

With a maximum power dissipation of 2 W the switch runs silently without a fan and operates reliably from -5 to 70 °C at 5 to 90 % humidity. The HDMI 2.0 link handles an 18 Gbps data rate and a 340 MHz pixel clock, delivering stable 4K@60Hz video with HDCP 2.2 compliance and built-in ESD protection for continuous daily use.
