The practical answer

For this exact Windows-only target, the KD-E20 is the documented topology. Each laptop port must combine DisplayPort 1.4 Multi-Stream Transport (MST), USB data and charging, and each side needs a suitable power adapter. This page is narrower than the general USB-C laptop qualification guide: 100W-class charging on both inputs is a hard requirement.

Compatible with limitations

AV Access KD-E20

Compatible with stated limitations

What this means for you: It combines two USB-C laptop inputs, dual 4K60, monitor-setting retention (EDID) and up to 100W charging, but requires DisplayPort 1.4 Multi-Stream Transport (MST) and external laptop power adapters.

Product-specific limits
  • macOS mirrors the two external displays on the Multi-Stream Transport (MST) topology.
  • Dual 4K60 requires both laptops to expose suitable DisplayPort video over USB-C.
  • The laptop's own USB-C power adapter is required to provide up to 100W charging.
  • high dynamic range (HDR) and variable refresh support are not confirmed in the published specification.
Evidence behind this assessment

6 recorded claims are manufacturer-confirmed, 1 are conservative inferences and 2 remain unresolved. Product evidence last checked 12 August 2026.

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.

Compatibility constraints

  • Both laptops must run Windows and support DisplayPort 1.4 Multi-Stream Transport (MST) on the selected USB-C port.
  • Each input needs a power adapter and cable capable of the laptop’s required wattage.
  • A laptop may accept 100W but still discharge under a workload that normally uses a larger proprietary charger.

Recommended setup sequence

  1. Confirm DisplayPort 1.4 Multi-Stream Transport (MST) and 100W-class USB-C charging on each exact port.
  2. Connect correctly rated power adapters and e-marked cables to both inputs.
  3. Verify dual extended 4K60 on each laptop before adding peripherals.
  4. Test charging under sustained workload and confirm display wake after switching.
