Capture cable identity, length and direction

Write down the exact product before reasoning about its class.

The useful distinction

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

Guide note · not an individual product specification

The useful distinction

Understand the requirement.

Scope of the factual anchorVESA directs users to device documentation for DisplayPort Alt Mode support and distinguishes USB-C video converter directions. [C090A]
Verified device listNot included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.

A note such as “HDMI adapter” loses the source and sink roles. Use explicit source → destination language in the stage labels and select the matching converter class.

Before you connect

What to check

  1. Record the maker and product identifier where available.
  2. Record the cable length as an observation, not a speed inference.
  3. Inspect any source and display direction labels.
  4. Attach the product page or manual used for the claim.

No universal length rule

This workflow does not derive a maximum supported mode from length, jacket color or perceived cable thickness. It collects evidence for a product-specific decision.
