4-Port Dual-Monitor KVM Switch
This DisplayPort KVM switch lets four computers share one keyboard, one mouse and two monitors. It supports extended, mirrored or spliced desktop layouts at up to 4K resolution. The unit includes two extra USB 2.0 hub ports for sharing peripherals such as flash drives or printers. Audio and microphone signals are also passed through to the active system.
Ideal for Multi-System Workstations
The switch suits professionals who operate several PCs or laptops side by side and need instant access to a dual-display setup. It works with Windows, Linux and Mac without extra drivers. Buyers who require monitor refresh rates above 60 Hz or who only have HDMI video outputs on their computers should consider a different solution.
Stable 4K 60 Hz Operation
Under continuous use the switch maintains 3840 x 2160 at 60 Hz with 4:4:4 colour sampling across both displays. Switching between systems is handled by hotkeys, mouse gestures, front-panel buttons, a wired remote or an auto-scan timer, all without interrupting the video signal. The USB 2.0 hub ports remain active during transitions so shared devices stay connected.

Questions about this item
Does the SMA KVM switch require each computer to have two DisplayPort outputs for the dual-monitor setup?
Yes, the switch connects four computers via four DisplayPort inputs and drives two DisplayPort monitors, so each computer must provide two DisplayPort video outputs for extended or mirrored 4K 60 Hz 4:4:4 operation.
Can I keep a 60 Hz DisplayPort monitor and still use the switch if my other monitor runs at a higher refresh rate?
The unit supports resolutions up to 4096×2160 at 60 Hz and does not support monitors with refresh rates above 60 Hz, so any connected display must operate at 60 Hz or lower.
How can I verify the switch is passing 4K 60 Hz 4:4:4 video and USB audio to both monitors after I connect everything?
Check each computer's display settings to confirm 3840×2160 at 60 Hz with 4:4:4 colour, ensure audio output routes to the switch's audio jack, and test hotkey, mouse, button, remote and auto-scan switching modes.
