The practical answer

For a MacBook-plus-desktop desk, the first requirement is two native Mac display streams, not merely two KVM output sockets. iDock M10 supplies a documented two-USB-C Mac path with charging; HDK202-M24 is the flexible desktop-style alternative when the Mac or dock exposes two independent video outputs. USB 3.x then carries the webcam and audio interface.

Product-specific limits
  • Native dual extended displays use two USB-C ports on a supported MacBook.
  • 3440×1440 is limited to 60Hz and a 5120×1440 display falls back to 3840×1080.
  • The Windows host still needs suitable display outputs for both monitors.
  • high dynamic range (HDR) and variable refresh support are not confirmed in the published specification.

High dynamic range (HDR): supported · Variable refresh (VRR): supported · Keeps monitor settings (EDID): supported

Product-specific limits
  • 4K240 and dual 4K144 are Display Stream Compression (DSC) modes, so every device and cable in the signal chain must support the required mode.
  • A Mac needs a separate video output for each display.
  • It does not charge a USB-C laptop.

Compatibility constraints

  • The selected Mac must natively support two external displays in the intended lid mode.
  • The iDock M10 uses two Mac USB-C ports; a single Multi-Stream Transport (MST) feed is not equivalent on macOS.
  • Webcams and audio interfaces share the upstream USB connection and may reconnect after switching.

Recommended setup sequence

  1. Confirm the exact Mac model’s native external-display limit.
  2. Prove two extended displays from the Mac using the intended adapters or dock.
  3. Add the KVM and verify display wake before connecting peripherals.
  4. Add the audio interface, then the webcam, and test switching during a real call.
