Dual-Computer Dual-Monitor Control

This HDMI 2.1 KVM switch lets you operate two computers or laptops with one keyboard, mouse and two extended or mirrored displays. A built-in USB 3.0 hub shares a single peripheral such as a printer, webcam or headset between both machines. The unit includes a wired remote, push-button, hotkey and mouse-gesture switching plus an auto-scan timer adjustable from 8 to 999 seconds.

Check Your Video Outputs Before Ordering

Each computer must supply two HDMI signals to fill both monitor ports; laptops with only one HDMI output will need an adapter or docking station. Monitors connect with their own HDMI cables, which are not included. The switch supports Windows, Linux and macOS without drivers, but verify that each source can drive the resolutions you plan to use.

Sustained 8K60 and High-Refresh 4K Operation

The HDMI 2.1 pathway delivers 7680×4320 at 30 or 60 Hz and 3840×2160 at 144 Hz continuously, with EDID emulation keeping display handshakes stable during long sessions. USB 3.0 peripheral bandwidth remains consistent while switching, and 3.5 mm stereo plus microphone pass-through stay active on the selected port without re-negotiation.

Questions about this item

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

The package supplies all cables and power adapters except the monitor cables, which normally come with the monitors themselves. Laptops without dual HDMI outputs will still need their own adapters.

Should I pick the 7680×4320@60 Hz mode or the 3840×2160@144 Hz mode for competitive gaming?

For competitive gaming the 3840×2160@144 Hz setting gives the higher refresh rate, while 7680×4320@60 Hz is intended for maximum desktop resolution.

When I run a game at 3840×2160@144 Hz through the switch, will the 144 Hz actually reach the monitor?

Yes, the HDMI 2.1 link supports 3840×2160 at 144 Hz, so the full refresh rate passes through to the display.
