Configuration guide

Two USB-C laptops + dual monitors + charging

What a two-laptop USB-C KVM must do to switch dual displays, USB peripherals and laptop power together.

Host linkSingle USB-C each

PowerUp to 100W

Main riskMulti-Stream Transport (MST) and charger requirements

The practical answer

For two Windows laptops with DisplayPort 1.4 Multi-Stream Transport (MST), the KD-E20 is the most direct match. It passes video, USB and up to 100W charging per laptop when the required power adapters are connected. If either laptop is a Mac, expect mirrored displays and choose a different topology.

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 is designed for two USB-C laptops, dual 4K60, monitor-setting retention (EDID) and up to 100W charging, but both hosts need DisplayPort 1.4 Multi-Stream Transport (MST) and their own power adapters.

Displays: 2
Video connections: 2 × USB-C (DP Alt Mode with Multi-Stream Transport (MST))
Published 4K ceiling: Single 60Hz · multi 60Hz
USB-C laptop charging: 100W

High dynamic range (HDR): not confirmed · Variable refresh (VRR): not confirmed · Keeps monitor settings (EDID): supported

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: It is designed around a MacBook plus PC arrangement, not two equivalent single-cable USB-C laptop inputs.

Displays: 2
Video connections: 2 × USB-C for Mac / HDMI 2.0 / DisplayPort 1.2a
Published 4K ceiling: Single 60Hz · multi 60Hz
USB-C laptop charging: 100W

High dynamic range (HDR): not confirmed · Variable refresh (VRR): not confirmed · Keeps monitor settings (EDID): supported

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

macOS does not extend two independent displays over the KD-E20 Multi-Stream Transport (MST) path.
A USB-C port carrying data or charging is not necessarily capable of DisplayPort Alt Mode.
Charging capacity depends on the connected laptop power adapters.

Recommended setup sequence

Check DP Alt Mode, DisplayPort 1.4 Multi-Stream Transport (MST) and charging support on both USB-C ports.
Connect each laptop's power adapter to the prescribed charging input.
Test dual extended 4K60 before adding peripherals.
Add webcam, storage and audio devices while checking USB bandwidth.
