4-Port HDMI KVM Switch for Four Computers

This HDMI KVM switch lets you control four computers with one keyboard, one mouse and a single 4K monitor. It also shares three USB 2.0 peripherals such as drives, printers or webcams across all connected systems. The unit includes four USB+HDMI combo cables, a wired remote button and a DC power cord for stable operation.

Passive Operation with External Power

The switch draws power from the supplied DC cord and has no internal fans, so it adds no audible noise to the workspace. Power consumption is limited to the switching logic and the three downstream USB 2.0 ports. Thermal output is negligible during normal desktop use and requires no active cooling.

Replaces Multiple Cables and Manual Swapping

This device replaces the need to physically unplug and replug video, keyboard, mouse and USB cables when moving between four machines. The jump is worth it when you regularly work across several desktops or laptops and want instant, button-press switching without software drivers. Buyers who need more than four computer ports or USB 3.0 speeds should look elsewhere.

Questions about this item

How do I connect the four combo cables and where do I plug the DC power cord?

Connect each USB+HDMI combo cable from a computer to one of the four input ports on the switch, then plug the DC power cord into the switch power jack and a 5 V 2 A adapter — the adapter is not included.

Which ports may need a different cable if I upgrade my peripherals later?

The three downstream ports are USB 2.0 only, so any USB 3.0 or newer device will fall back to 2.0 speeds; the four upstream combo cables carry both HDMI and USB 2.0 and cannot be separated.

What resolution ceiling will I hit first when running four 4K sources continuously?

The switch tops out at 3840×2160 at 60 Hz with YUV 4:4:4 colour, so any source trying to push higher refresh rates or bit-depths will be limited to that ceiling.
