Interface and capability
| Standard / protocol | HDMI Premium High Speed cable category. Connector appearance alone does not establish compatibility. |
|---|---|
| Endpoint / pinout | 19-pin Type A HDMI TMDS link with DDC, CEC and auxiliary channels per endpoint support. |
| Capability / limits | Certification tests 18 Gbit/s capability; maximum certified length is the specific assembly, not an unlimited category guarantee. |
| Certification / length | Standards define interface requirements, not every assembly’s performance. Certification, mode, current/power rating, direction and maximum length belong to the exact product/revision and complete channel; verify its manufacturer specification. Do not infer certification from connector shape or marketing terminology. |
Compatibility & handling
- Look for the official cable label/QR verification. Confirm device 4K60/HDR support; long runs may require a separately qualified active cable.
- Inspect connector keying, latch, contact condition, shielding, jacket and model/revision marking. Stop if contacts are bent, loose, scorched, corroded or mismatched.
- Route without tension or sharp bends; follow product bend-radius, strain-relief, current and environmental limits. Test at the intended protocol and mode—physical fit is not a compatibility test.
