Dual-computer dual-monitor KVM

This HDMI KVM switch connects two computers to two monitors and three USB 3.0 peripherals. Separate audio and microphone ports let each system keep its own headset. Push-button and wired-remote switching give instant control without software. The unit ships with cables, a power adapter and a manual.

4K@60Hz dual-head capacity

Each computer must use both HDMI inputs to drive both outputs simultaneously. The switch passes resolutions up to 4096×2160 at 60 Hz, plus 2K, 1080p and 3D formats. Adaptive EDID keeps display information correct on every changeover. Bandwidth limits mean higher refresh rates or uncompressed 4K beyond 60 Hz are not supported.

Passive cooling and external power

A DC 5 V adapter supplies all switching logic and the three USB 3.0 ports. No internal fan means silent operation on a desk. The compact 3.94 × 1.97 × 0.79 inch enclosure weighs 1.15 pounds and runs warm only under sustained full-port load. Power draw scales with attached peripherals.

Questions about this item

Will my existing 1080P monitors work with the 4K@60Hz capability of this SMA KVM switch?

Yes, the switch supports 1080P, 2K, 3D and 4K@60Hz, so your current monitors will display correctly at their native resolution while the switch is ready for future 4K upgrades.

How do I confirm the SMA KVM switch is routing video and USB correctly after I connect both computers and both monitors?

The front LED indicators show which computer is active on each HDMI output; press the push button or wired remote and watch the LEDs change to verify switching, then check that keyboard, mouse and the three USB 3.0 devices follow the selected PC.

What cables and accessories are included with the SMA HDMI KVM switch and what must I provide?

The box contains the KVM unit, two USB 3.0 cables, a DC 5V power adapter, a wired remote button and a user manual; you must supply four HDMI cables (two per computer) and any audio cables for the separate mic and headset ports.
