2-port HDMI USB 3.0 KVM

This KVM switch connects two computers to two HDMI monitors using a single keyboard and mouse set. It handles 4K resolution at 60 Hz and passes USB 3.0 data for peripherals such as scanners, drives or cameras. A 3.5 mm audio jack with a built-in DAC extracts stereo sound from either source. The aluminium-alloy enclosure measures 111.8 by 63.2 by 24.5 mm.

Dual-monitor multi-system control

It suits users who need to operate two PCs, laptops or consoles side-by-side while sharing two displays and USB devices. Switching is done by a front-panel button, configurable hotkeys or the supplied IR remote. Buyers who only have a single monitor or who require more than two computer ports should look at a different product.

4K 60 Hz video with USB 3.0

The decisive specification is the 3840 x 2160 resolution at 60 Hz combined with USB 3.0 pass-through, which determines whether the switch can drive both monitors at full fidelity while keeping high-speed peripherals functional.

Questions about this item

Does this KVM switch use HDMI 2.0 and HDCP 2.2, and what resolution and refresh rate does that allow?

The unit carries HDMI 2.0b with HDCP 2.2, so it passes 3840 x 2160 at 60 Hz or 1080p at 144 Hz to each monitor.

How much desk space does the aluminium chassis need?

The chassis measures 111.8 mm wide by 63.2 mm deep by 24.5 mm high, so allow at least that footprint plus cable clearance.

What are the three ways to switch between the two connected PCs, and which step do users often miss?

Press the front Select button, use the hotkey sequence Ctrl+Shift+1 or Ctrl+Shift+2, or use the IR remote; the step often missed is that the hotkey function must be enabled with Ctrl+Shift+K before it will work.
