Four-monitor KVM for dual desktops

This SMA 204DH switch lets two desktop PCs share four displays, a keyboard, a mouse and up to four USB 3.0 peripherals. It is built for workstations that need simultaneous multi-monitor output from each computer. Laptops and systems with integrated graphics are not supported.

8K60 HDMI and 4K120 DisplayPort

The decisive spec is the video bandwidth: HDMI ports deliver 8K at 60 Hz or 4K at 120 Hz, while DisplayPort inputs handle 8K at 30 Hz and 4K at 120 Hz. Each PC must provide two HDMI and two DisplayPort outputs to drive all four monitors.

Four USB 3.0 ports at 5 Gbps

The hub handles keyboards, mice, printers and other USB 3.0 devices with backward compatibility to USB 1.1 and 2.0. It will not power high-draw peripherals without the included 12 V adapter, and each computer needs its own USB link for the ports to function.

Questions about this item

What does the 8K@60Hz rating on the HDMI ports mean for my actual display setup?

The HDMI ports can drive each of the four monitors at 8K resolution and 60Hz refresh rate, provided the connected desktop PC has a dedicated graphics card with two HDMI 2.1 outputs and you use certified HDMI 2.1 cables.

How does the DisplayPort 1.4 interface limit the 8K output on this KVM?

The DP ports are capped at 8K@30Hz because they use the DisplayPort 1.4 standard; 4K@120Hz is the highest refresh rate available over DP on this unit.

What physical connections and space does the 204DH need to sit on my desk?

The switch measures 5.91 x 2.76 x 2.36 inches and requires a 12V DC power adapter plus two HDMI, two DisplayPort and one USB 3.0 cable from each computer to the four monitor outputs.
