Triple-Monitor KVM for Two Computers
This SMA KC203DH switch lets you control two desktops or laptops with one keyboard, one mouse and three displays. It accepts two DisplayPort 1.4 inputs and one HDMI 2.1 input per computer, then routes the signals to three monitors. Four USB 3.0 ports share peripherals such as printers or scanners at up to 5 Gbps. A wired remote button is included for convenient switching away from the main unit.
Sustained 8K and High-Refresh Operation
The HDMI path maintains 8K at 60 Hz or 4K at 120 Hz continuously, while each DisplayPort path runs 8K at 30 Hz or 4K at 144 Hz without throttling. Both interfaces are backward compatible with lower resolutions and refresh rates. The supplied 12 V DC adapter powers the switch reliably during long work or gaming sessions, keeping video stable and USB devices enumerated.
Compact Metal Chassis with Front-Panel Controls
The 10 x 8 x 4 cm enclosure fits neatly on a desk and includes push-button switching plus LED indicators for active ports. Cables connect at the rear: two DP 1.4 cables, one HDMI 2.1 cable and two USB 3.0 cables are bundled. Each computer must provide two DisplayPort outputs and one HDMI output for the three-monitor layout to function. The switch supports extended mode for three distinct desktops and copy mode for three identical images. Buyers whose systems lack the required video outputs cannot use all three monitors.

Questions about this item
Does the KC203DH generate noticeable heat or noise when left running all day?
The unit has no fan and draws power from the supplied 12 V adapter, so it runs silently and stays cool during continuous use.
What cables and ports must my two computers already provide to use all three monitors?
Each computer needs two DisplayPort 1.4 outputs and one HDMI 2.1 output to drive the three monitor ports simultaneously.
Will the switch pass 4K 144 Hz from an older GPU that only has DisplayPort 1.2?
The switch is backward compatible, so a DP 1.2 source will work but will be limited to that standard’s maximum resolution and refresh rate.
