Dual-computer dual-monitor control

This SMA KVM switch lets two computers share two HDMI monitors and a single keyboard and mouse set. It is aimed at desk setups that need to toggle between a work PC and a personal machine or a console without replugging cables. The metal chassis houses the switching logic and four USB ports for peripheral sharing. Mac systems are not recommended due to compatibility limits.

Steady 4K at 30 Hz output

The switch maintains a stable 3840x2160 resolution at 30 Hz across both displays during extended sessions. It also handles 1920x1080 at 60 Hz when higher refresh is preferred. Video bandwidth is sustained through HDMI cables up to five metres at 1080p, so signal integrity holds for typical desk distances. Copy mode duplicates the primary screen while extend mode spans the desktop across both monitors.

Metal build with front push-button and remote

The all-metal enclosure resists heat buildup and physical knocks in daily use. Switching is done via a front-panel button or the included wired remote, keeping the main unit tucked away. Four USB ports — two USB 1.1 and two USB 2.0 — accept keyboards, mice, drives, printers or webcams. Note that only one HDMI cable is supplied; a full two-computer dual-monitor install requires five cables in total.

Questions about this item

Does the SMA dual-monitor KVM run hot or draw noticeable power when both PCs and both 4K@30 Hz displays are active all day?

The metal chassis acts as a passive heatsink and the unit draws power only from the connected USB cables, so it stays cool and adds no measurable load during continuous dual 4K@30 Hz operation.

Which cables and peripherals must I already have to connect two computers and two monitors to this switch?

You need five HDMI cables (one is included), two USB-A-to-USB-B cables for the PC links, plus your keyboard, mouse and any USB 2.0 devices you want to share across the four downstream ports.

Will my older 1080p@60 Hz monitors and USB 1.1 keyboard work reliably through this KVM alongside a newer 4K@30 Hz display?

Yes — the switch supports 1920×1080@60 Hz on each port and provides two USB 1.1 plus two USB 2.0 downstream ports, so legacy monitors and peripherals operate alongside a 3840×2160@30 Hz screen without extra setup.
