Four-Port Dual-Monitor KVM Switch

This SMA KVM switch lets one keyboard, one mouse and two HDMI monitors control four separate computers. It is aimed at users who run multiple workstations, servers or gaming rigs from a single desk and want to avoid swapping cables or peripheral sets.

HDMI 2.1 with 8K60 and 4K120 Support

The switch passes HDMI 2.1 signals up to 8K at 60 Hz and 4K at 120 Hz, with backward compatibility down to 1080p. Extended, mirrored or spliced dual-monitor layouts are supported, provided each connected computer supplies two HDMI outputs.

Bus-Powered Operation with Supplied Adapter

The unit draws power from the included external adapter, so no separate power supply is required. Three USB 3.0 ports and one USB 2.0 port share peripherals at up to 5 Gbps, while the USB 2.0 port is intended for 2.4 GHz wireless dongles to avoid interference.

Questions about this item

What does 8K@60Hz mean for my dual-monitor setup?

Each HDMI output can drive an 8K display at 60 frames per second, or two 4K monitors at 120 Hz, provided your graphics cards support those modes.

How does HDMI 2.1 limit the video bandwidth in practice?

The HDMI 2.1 ports carry up to 8K@60 Hz or 4K@144 Hz; any higher refresh rate or colour depth would exceed the link capacity.

What physical space and connections does the unit need?

The switch measures 9.13 by 6.85 by 2.2 inches, weighs 1.61 pounds, and requires four HDMI inputs, two HDMI outputs, USB cables for each PC, and the included power adapter.
