Four-computer dual-monitor KVM
The SMA switch lets four computers share two displays and four USB 3.0 peripherals. Each host must provide one HDMI 2.1 and one DisplayPort 1.4 output. Front-panel buttons and the included wired remote change the active system with LED indication.
Sustained switching and data throughput
USB 3.0 ports deliver up to 5 Gbps for keyboards, mice, printers or scanners during long sessions. Video paths maintain 4K at 144 Hz over HDMI and 4K at 120 Hz over DisplayPort without frame drops when the host and cables meet the required specifications.
Thermals noise and power draw
The unit ships with a 12 V DC adapter that powers the switching logic and downstream USB ports. No internal fan is present, so operation is silent. The metal chassis dissipates heat passively across its 21.2 by 7.8 by 4.5 centimetre footprint.

Questions about this item
Does the SMA KVM switch need active cooling or does it run silently all day?
The unit has no fan and relies on passive heat dissipation; the included 12 V DC adapter supplies all power so it runs silently during continuous use.
What cables and ports must each computer already provide to connect four systems to this switch?
Every computer requires one HDMI 2.1 output and one DisplayPort 1.4 output; the package includes four USB 3.0 cables for the keyboard, mouse and other peripherals.
Will my older 1080P monitors work alongside a newer 4K 144 Hz display on the two outputs?
Yes — the switch is backward compatible with 1080P and 2K@144 Hz, so mixed-resolution monitors can be used simultaneously in extended or copy mode.
