Which power number matters?Check negotiated host delivery, not just supply sizeUp to 96 W host delivery; 150 W names the adapter

ASUS: SimPro Dock 2 specification and model list · ASUS DC500: display compression and 96 W host charging · ASUS DC500: ports, operating systems and output modes

For an ExpertBook already using SimPro 2

Record the complete B-series code and the working display modes. Keep that known arrangement as your comparison. Move to DC500 only after identifying the particular limitation it would solve; a newer connector standard is not itself evidence of better results for your screens.

For a Zenbook or shared desk

Use the exact device’s port specifications, then confirm the complete arrangement. The SimPro list is not a blanket approval for all ASUS laptops, and a dock specification listing macOS does not promise three independent Mac screens. See the UX5406SA/AA choices.

Compare the full cable kit

  1. Match each screen input to a usable dock output.
  2. Account for a downstream Thunderbolt video adapter if your DC500 layout needs one.
  3. Check the laptop’s charging requirement and the supplied host cable.
  4. Confirm the complete screen modes with the manufacturer when the finder labels the pair as unconfirmed.
