Triple-monitor KVM for two computers

This DisplayPort KVM switch lets two PCs or laptops share three monitors and four USB 3.0 peripherals from a single keyboard and mouse. It supports duplicate and extended desktop modes so the same content can span all screens or each monitor can show a different workspace. The unit requires each source to provide three DisplayPort outputs. LED indicators show the active computer at a glance.

Passive cooling with external 12 V power

The switch draws power from an included 12 V DC adapter, giving stable operation even when high-draw USB devices are connected. No internal fan is present, so the device runs silently on a desk or in a rack. Power consumption scales with the attached peripherals and the video bandwidth in use. The wired remote draws negligible current from the same supply.

Compact metal chassis

The enclosure measures 5.85 by 2.5 by 1.9 inches and weighs 1.39 pounds, fitting easily between monitors or under a monitor stand. Three DisplayPort outputs and four USB 3.0 ports face the rear, while a push button on the front toggles between the two computers. A wired remote extends the switching control to a more convenient spot without moving the main unit.

Questions about this item

How do I connect two computers to the SMA 203DP so three monitors share one keyboard and mouse?

Connect each PC with one USB 3.0 cable and three DP cables to the switch, then plug all three monitors into OUT A, OUT B and OUT C. The graphics card must provide three DP outputs per computer for full triple-monitor operation.

What USB peripheral limits appear after long sessions on the four USB 3.0 ports?

The four USB 3.0 ports share a 5 Gbps aggregate bandwidth and the 12 V 1 A adapter caps total bus power; high-draw devices may need their own supply during sustained transfers.

Which resolution ceiling hits first when I run all three displays at high refresh rates?

The DP 1.4 link tops out at 8K 60 Hz or 4K 120 Hz per stream; pushing three 4K 120 Hz signals simultaneously will saturate the link before the panel limits do.
