Triple-monitor KVM for two computers

The SMA KVM203DH lets one keyboard, mouse and four USB 3.0 peripherals control two PCs across three displays. Each computer must provide two DisplayPort outputs and one HDMI output plus a USB-A port. The switch handles 8K at 60 Hz and 4K at 144 Hz, dropping back to 1080p when needed.

Replaces cable-swapping and single-screen KVMs

Moving from manual plug changes or a dual-monitor switch to this unit is worthwhile when both workstations already have the required three video ports and you need simultaneous triple-head operation. It adds nothing if your hardware lacks the second DisplayPort or the HDMI 2.1 link.

Three displays at 8K 60 Hz or 4K 144 Hz

The box drives three monitors — two DisplayPort, one HDMI — at the stated peak resolutions using certified 1.5 m cables. Bandwidth runs out beyond 8K 60 Hz, and extended desktop mode requires each PC to support multi-monitor output natively.

Questions about this item

What ports must each computer have to connect this KVM203DH switch?

Each computer needs two DisplayPort 1.4 outputs, one HDMI 2.1 output and one USB-A 3.0 port for the included cables.

Which step do users most often miss when installing the unit?

Connecting the 12 V power adapter before linking any video or USB cables; the switch will not pass 8K@60 Hz or 4K@144 Hz signals without external power.

What cable lengths and versions should I keep on hand for future replacements?

Use DP 1.4 and HDMI 2.1 cables no longer than 1.5 metres to maintain 8K@60 Hz or 4K@144 Hz performance when swapping cables later.
