  • Notebook (generic)

    On Linux, the OS cannot physically turn off the laptop's built-in display, so the number of usable external displays is one less than the dock's listed maximum.

  • ROG Ally

    A ROG Ally user reports the dock (rated 130W) doesn't deliver the confirmed 65W the Ally requires to unlock its 30W Turbo Mode — Windows reports the charger as providing less than full power and caps performance accordingly.
