Four-computer dual-monitor KVM

The DKM402C lets one keyboard, mouse and two monitors control four computers through HDMI and DisplayPort inputs. It suits multi-system workstations, server rooms or streaming setups where desk space and peripheral clutter must stay minimal. No drivers are required for Windows, Mac, Linux or Unix hosts.

Three USB 3.0 ports and audio jacks

The switch adds three USB 3.0 ports that share scanners, printers, drives or other peripherals across all connected PCs at up to 5 Gbps. Separate headphone and microphone sockets route analogue audio from the active computer without extra cables or software mixers.

HDMI and DisplayPort bandwidth ceiling

Each video path tops out at 4K 60 Hz YUV 4:4:4 with HDCP 1.4 and HDR 2.2, so higher refresh rates or deeper colour formats are not possible. Dual-monitor extended or mirrored modes depend entirely on the host graphics card supporting multi-stream output.

Questions about this item

Will the DC power adapter need replacing after extended use?

The unit ships with a DC power adapter; if it fails you can swap in a matching voltage and amperage supply without opening the switch.

What limits 4K 60 Hz output when both monitors run all day?

The switch supports 4K 60 Hz YUV 4:4:4, HDCP 1.4 and HDR 2.2, so the first bottleneck is your graphics card’s dual-display capability.

Does the box get hot or noisy during continuous operation?

The 7.1 × 2.8 × 1.2 inch enclosure has no fan and draws little power, so it stays silent and only warm to the touch.
