A dock port count is not a simultaneous display claim

Count requirements and shared resources, not just connectors.

The useful distinction

Use the exact model, port label and documentation section; this is a planning method rather than an automatic identification.

Claim inspection dates: 2026-10-01 · Independent review pending

Guide note · not an individual product specification

The useful distinction

Understand the requirement.

CalDigit states that TS4 display functionality depends on host capabilities and describes additional requirements for some display modes. [C086A]

Scope of the factual anchorCalDigit states that TS4 display functionality depends on host capabilities and describes additional requirements for some display modes. [C086A]
Verified device listNot included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.

Create a serial research plan for each path and retain the shared dock context in its title. The result stays outside modeled compatibility when dock or multi-stage requirements remain.

Before you connect

What to check

  1. Write how many displays must work at the same time.
  2. Record each requested resolution, refresh rate and color requirement.
  3. Find the host-specific display matrix.
  4. Keep compression and operating-system requirements visible.

What this release does not calculate

There is no lane allocator, compression negotiation, driver detector or branch-topology solver. More complete annotations do not unlock an unsupported simulation.
