Exact scope

CalDigit TS3 Plus only; native Thunderbolt mode and the six named M1–M4 Pro/Max MacBook Pro hosts are the active worksheet scope.

Selected documented host/display port groups only; not a complete physical inventory or hardware test. Counts and roles follow the named manufacturer source; no inferred chassis geometry.

Same connector form, different documented roles

USB-C: Computer / Thunderbolt upstream — Upstream host · Downstream Thunderbolt display paths — Display output / downstream

Do not transfer a capability from one location to another merely because the connector outline matches.

Upstream host

Computer / Thunderbolt upstream

Use the port designated for the computer and the manufacturer specified upstream cable.

Display output / downstream

Downstream Thunderbolt display paths

Spare Thunderbolt sockets can carry display paths; their physical count does not override the scoped simultaneous-display limit.

Read before using the profile

  • Scoped native Thunderbolt Mac path: dual 4K60 or single 5K60 manufacturer ceiling; M1 Pro/Max dual display support is explicitly documented.
  • Dedicated DisplayPort plus spare Thunderbolt are separate native paths. DisplayPort-to-HDMI requires active conversion.
  • No HBR/DSC table conditions are invented. OS and firmware requirements still need current source and actual device review.
