4-Port HDMI KVM Switch with USB 2.0 Hub

This SMA KVM switch lets you control four computers from a single USB keyboard, mouse and monitor. It includes an integrated USB 2.0 hub so peripherals such as drives, scanners or printers can be shared across all connected systems. The unit supports plug-and-play operation with no driver installation required. A metal housing with side ventilation provides passive cooling.

Ideal for multi-system desks.

The switch suits users who need to manage several PCs, laptops, consoles or media players through one HDMI display and USB console. It works with Windows, macOS and common gaming devices. Buyers whose sources or monitors use DisplayPort, USB-C video or require 4K above 60 Hz should look at a different switch. The USB hub is limited to 2.0 speeds.

Handles 4K 60 Hz 4:4:4 and 1080p; max four computers

Video bandwidth reaches 18 Gbps, delivering 4K at 60 Hz with YUV 4:4:4 chroma and full 1080p support. HDCP 2.2 compliance protects premium content playback. You can connect up to four HDMI sources and switch via front button or keyboard hot-keys. The USB 2.0 hub shares one peripheral set across those four hosts.

Questions about this item

What type of USB port does the hub use for the keyboard and mouse?

The integrated hub is USB 2.0, so the shared keyboard and mouse connect through that standard.

Will the switch pass 4K 60 Hz from each of the four HDMI sources?

Yes, each of the four HDMI 2.0 inputs supports 4K at 60 Hz with full 18 G bandwidth and YUV4:4:4 chroma sampling.

How can I confirm the automatic cycling mode is active after pressing the hot-key?

After enabling cyclic mode with Ctrl+Ctrl+S the unit will switch to the next computer every 5 seconds, so the on-screen source changes visibly.
