Two USB-C laptops + dual monitors + 100W charging

The exact host requirements for a two-laptop, two-monitor, 100W single-cable desk.

The practical answer

The KD-E20 is purpose-built for this arrangement. It is a qualified match for two Windows laptops whose USB-C ports support DisplayPort 1.4 Multi-Stream Transport (MST), data and charging. It is not a dual-extended-display solution for Macs because macOS mirrors Multi-Stream Transport (MST) displays.

These statuses apply to this exact configuration, not to the product in every possible setup.

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.

Not compatible

AV Access iDock M10

Not supported by published specifications

What this means for you: Its host arrangement is a MacBook plus PC, not two symmetric USB-C laptop inputs.

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 laptop USB-C ports must support DP Alt Mode and DisplayPort 1.4 Multi-Stream Transport (MST).
  • macOS mirrors the two displays on this topology.
  • The KVM routes charging from connected power adapters; it does not create 100W by itself.

Recommended setup sequence

  1. Check each laptop's USB-C video and charging specification.
  2. Supply the correct power adapter for each laptop input.
  3. Verify dual extended 4K60 before adding USB devices.
  4. Test charging under a sustained CPU and GPU workload.
