One laptop connection. A much larger workspace.
Connect a compatible USB-C laptop to displays, fast USB accessories, wired networking and power through a desktop dock. KD-S03 provides two DisplayPort outputs and one HDMI output, with the supported screen arrangement determined by the laptop’s native video capability.

Know what connects where.
Connection overview. Check the requirements below for the exact ports, cable type and supported operating mode.
Three screens, with the right host
The model manual specifies up to two 4K60 screens plus one 4K30 screen when the host provides DP 1.4 HBR3 with DSC. A lower-bandwidth host supports lower combinations; three display connectors do not guarantee three 4K60 screens.
Keep the everyday ports within reach
Selected front USB-A and USB-C data ports support up to 10Gbps. Additional rear USB ports, an SDXC reader, Gigabit Ethernet and a headset jack provide a practical home for desk accessories.
Dock and charge in one step
The included power supply enables up to 100W USB-C charging for a compatible laptop. Connect the full-featured host cable to a port that supports video, data and the laptop’s required charging mode.
Make sure it fits your setup.
Windows display capability
Independent extended screens require supported DisplayPort MST. DP 1.4 HBR3 and DSC are required for the highest documented triple-screen combination.
Mac display behaviour
macOS does not extend separate desktops across these MST outputs; the external screens mirror one another.
One computer at a time
KD-S03 is a single-host docking station. It is not a KVM switch for changing between two connected computers.
