Adapters

This is what matters about Cable Matters USB-C to 8K DisplayPort Multiport Adapter with Power Delivery (201046).

About

A DisplayPort 1.4 adapter combining video output with 100W USB-C Power Delivery pass-through on the same bus — the shared lane allocation between video and Fast Role Swap charging makes DSC 1.2 mandatory for anything above 8K@30Hz or 4K@120Hz. Without host-side DSC support, it caps at 8K@30Hz or 4K@120Hz; with DSC, 8K@60Hz or 4K@240Hz.

Confirmed with

  • Steam Deck

    Negative evidence: "A 'why doesn't this work' dock: Cable Matters 201046... not the steam deck" — the hub fails to process Multi-Stream Transport (display daisy-chaining) with the Steam Deck despite working on HP docking stations.

    Confirmed — caveat
  • Notebook (generic)

    Works on HP ProBook docking setups; negative evidence on a Razer Blade Stealth where the asymmetric PD controller is reported to induce severe throttling by misreading a chronic power deficit.
