Two-Computer Dual-Monitor KVM
This KVM switch lets one keyboard, one mouse and two monitors control two separate computers. It accepts two HDMI inputs per system and provides two HDMI outputs for dual-display operation. Four USB 3.0 ports share peripherals such as printers, keyboards and mice across both machines. A 3.5 mm audio jack switches sound automatically with the active computer.
Sustained Operation with No Extra Power
The unit draws all required power from the connected computers so no external adapter is needed. Video passes through at up to 4K@60 Hz and remains stable during long sessions; the switch also handles 1080P@120 Hz for high-refresh workflows. USB 3.0 ports maintain 5 Gbps throughput while switching between hosts without dropping connected devices. LED indicators show the active channel at a glance.
Check Your Computer Video Outputs First
Each computer must provide two HDMI outputs to use extended or mirrored dual-monitor modes; the switch cannot add this capability. Verify that your graphics hardware supports the desired resolution and refresh rate combination. Hot-key switching requires a standard USB keyboard; some compact or gaming keyboards may not trigger the command sequence. The included cables are USB 3.0 and USB Type-C for host connections.

Questions about this item
How much heat or fan noise does the SMA 4K HDMI KVM Switch produce when left running all day?
The unit requires no additional power supply and has no fan, so it adds no measurable heat or audible noise during continuous operation.
Which cables or ports must my two computers already have to use this 2×2 KVM switch?
Each computer needs two HDMI output ports and at least one USB 3.0 or USB-C port for the included cables.
Will the switch pass 1080P@120Hz from an older GPU to a modern monitor without downscaling?
Yes, the switch is backward compatible with 1080P@120Hz, so an older GPU running at that rate will display correctly on a newer monitor.
