The practical answer

For two desktop-style hosts, choose the video topology first and insist on confirmed USB 3.x for the shared peripherals. HKS202-M24 is the cleaner all-HDMI route; HDK202-M24 fits a desk where every computer can provide the required mixed HDMI and DisplayPort signals. Neither arrangement depends on laptop charging or a one-cable USB-C host path.

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.

Product-specific limits
  • Single 4K240 and dual 4K above 120Hz depend on Display Stream Compression (DSC) and the complete GPU, monitor and cable chain.
  • The manufacturer lists 3440×1440 up to 144Hz and 5120×1440 up to 120Hz on a single output.
  • A Mac needs a separate video output for each display.
  • It does not charge a USB-C laptop.

Product-specific limits
  • Most Macs mirror two displays on the single-cable Multi-Stream Transport (MST) path rather than extending them.
  • 3440×1440 is limited to 60Hz and a 5120×1440 display falls back to 3840×1080.
  • Power delivery is up to 60W.
  • high dynamic range (HDR) and variable refresh support are not confirmed in the published specification.

Compatibility constraints

  • Every desktop needs one independent video signal for each monitor.
  • A high-resolution webcam can consume much of the shared upstream USB bandwidth.
  • Some USB audio interfaces need re-selection after the KVM switches hosts.

Recommended setup sequence

  1. Map the two simultaneous video outputs available on each desktop.
  2. Prove dual 4K60 through the selected connector path before adding USB devices.
  3. Add the audio interface and confirm stable reconnect behaviour.
  4. Add the webcam at its intended resolution and frame rate, then test repeated switching.
