Dual Monitor HDMI KVM Switch 4K 60Hz

This SMA KVM switch lets you operate two computers using a single keyboard, mouse and dual monitor setup. It accepts two HDMI inputs from each system and routes them to two HDMI outputs, supporting extended, mirrored or crisscross display modes. The unit handles video resolutions up to 3840x2160 at 60Hz and 1080p at 144Hz for smooth visuals. It is built for users who need to share peripherals and dual screens between two workstations.

Verify HDMI 2.0 outputs

Before ordering, confirm each computer provides two HDMI 2.0 ports capable of 4K at 60Hz and at least one USB 3.0 Type-A port for the upstream connection. The switch includes two USB data cables and one USB power cable, so each host needs a free USB port for data and the switch itself requires a 5V power source. Ensure your monitors have HDMI inputs matching the 3840x2160 resolution and that your operating system is among the supported Windows, macOS, Linux or Unix versions.

Aluminium shell dissipates heat during continuous

The aluminium alloy chassis acts as a passive heatsink, maintaining stable signal integrity during extended sessions with frequent hotkey, front-panel or IR remote switching. USB 3.0 ports sustain high-current peripheral operation without throttling, while the integrated DAC delivers consistent 2.0-channel audio through the 3.5mm jack. EDID emulation keeps display handshakes reliable across long uptime, preventing resolution drops when toggling between the two connected computers.

Questions about this item

Does the box include every cable I need to connect two computers and two monitors?

The package supplies the KVM switch, two USB data cables, one USB power cable, an IR remote and a manual; you must provide four HDMI cables yourself.

Should I choose this 2-port model or a larger one if I only have two PCs?

This unit is built for exactly two computers and two monitors, so it matches a two-PC setup without extra unused ports.

What does the 4K 60 Hz rating mean when I am actually gaming at 1080p?

The switch passes 1080p at up to 144 Hz and 120 Hz, so high-refresh gaming works while the 4K 60 Hz ceiling applies only to 3840×2160 output.
