USB-IF cable markings distinguish charging power from data-rate capability.

Replace vague “full-featured” marketing with a task checklist.
The useful distinction
List the exact required data mode, video transport, charging rating and cable length. One label is not evidence that every maximum can be achieved simultaneously.
Cable / adapter note · not an individual product specification
CAPABILITY DESKEvidence-scoped · CABLE / TWO RATINGS
Every USB-C cable has at least two capability questions
No. Record the published USB data rate and the cable’s power rating independently, then check support for the required display path and cable length. USB-IF cable labeling distinguishes performance and power; charging-only behavior should not be mistaken for a defective data port.
What still needs verification?
Write down the exact data-rate label and watts on the cable or its model documentation.
Check cable length and whether active signaling imposes special compatibility requirements.
Verify the host and destination requirements for data, display, and power separately.

Buying a charge-rated cable for a high-bandwidth monitor or dock without checking its data/video qualification.
USB-IF cable markings distinguish charging power from data-rate capability. [C047A]
USB-IF’s cable-logo guidance conditions licensed logo use on program qualification and listing. Its cable guidance also states that a certified cable does not increase the capabilities of the connected host or device. [C047B]
USB-IF’s public Product Search says members maintain the certified-product entries and the default display covers only the last two years; a date filter can expose older entries, which may not meet current program requirements. [C047C]
VIA Labs describes its VL153 electronic marker as optimized for passive USB Type-C cables and supporting passive Thunderbolt 3/4 cables. This shows why electronic-marker presence alone does not establish signal-conditioning-active construction. [C047D]

Verified device list
Not included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.
This is a scoped requirements guide, not an interoperability certification. It does not test hardware, calculate an arbitrary display timing, or replace the exact product documentation. A missing capability stays unknown.

What to check
Verify a specific data mode, not only a family name.
Check video transport and direction where relevant.
Record power rating independently and use the device’s supported charging guidance.
