Four-PC Dual-Monitor KVM Switch
This KVM switch lets four desktop computers or laptops share one keyboard, one mouse and two monitors. Each system connects through both an HDMI and a DisplayPort input plus a USB link, so video and peripheral signals stay synchronised. Push-button and infrared remote switching give instant control without software installation.
Included Cables and Power Adapter
The package supplies four USB 3.0 Type-A-to-A cables for the upstream PC links and a 12 V 1 A external power adapter for stable operation. An infrared receiver cable and a handheld remote (batteries not included) enable switching from a distance, while the rear-mounted ports keep the desk surface clear of cable clutter.
Check Video Outputs and Cable Requirements
Verify that every computer you plan to connect provides both an HDMI and a DisplayPort video output; the switch expects one of each per system. HDMI and DisplayPort cables for the PC-to-switch and switch-to-monitor runs are not included, so source them separately. The unit supports resolutions up to 8K at 60 Hz and 4K at 144 Hz, with backward compatibility down to 1080p at 240 Hz.

Questions about this item
Will the USB 3.0 ports or the 12V 1A power supply need replacement first?
The unit ships with a 12V 1A external power supply and four USB 3.0 ports rated at 5 Gbps; the power supply is the only external component that may require replacement over time.
What resolution limit appears first when both monitors run at high refresh rates all day?
Dual-monitor output is specified up to 4K 144 Hz; pushing both displays beyond that resolution or refresh rate will hit the switch’s video bandwidth ceiling first.
How much heat or fan noise does the KVM produce during continuous 24-hour operation?
The device has no fan and draws power from the included 12V 1A adapter, so it runs silently with only minimal warmth under sustained use.
