Confirmed with

  • Notebook (generic)

    Base-tier Apple Silicon (M1/M2/M3, not Pro/Max) lacks internal MST support, restricting the dock to extending a single external display — any additional monitor mirrors instead. This limitation also applies to Windows laptops confined to plain USB-C Alt Mode. Reaching 8K@60Hz requires DSC 1.2 compression support on the host.
