Displays: form and signal direction
Write source output, converter input/output and display input in that order. Similar ends do not make a converter reversible.

Which direction and supported signal path does the equipment document?
| Clue or question | Supported distinction | Sources |
|---|---|---|
| HDMI Type C / Type D | Mini HDMI and Micro HDMI are distinct forms. Compare an identified role and viewing side; on-screen size is not a measurement. | S038 |
| Mini DisplayPort / Thunderbolt | A shared outline does not establish the signal. The cited Apple Thunderbolt adapter excludes Mini DisplayPort displays. | S016 S521 |
| Passive DP to HDMI | The cited passive DP2HDMI2 class needs a DP++ source. Check the named product and complete mode. | S846 |
| Active DP to HDMI | Active conversion is a distinct product class. Direction, source acceptance and output limits remain product-specific. | S035 |
| HDMI to USB-C | Investigate a product explicitly documenting this direction and the display input transport. Do not reverse an ordinary opposite-direction adapter. | S003 S012 S035 |
| Cable category / whole system | A named HDMI cable class or certification does not establish every optional feature of the source/display. | S056 S052 S057 S012 |
Check the complete task
- Name the exact source port, converter and selected display input; trace source -> converter -> display without reversing the arrows.
- Write resolution, refresh rate and any required color/HDR feature as a complete mode. Check each stage, power and platform requirements.
- If passive conversion is proposed, obtain explicit source DP++ evidence. Active wording alone is not a universal higher-mode guarantee.
Text and conceptual comparisons only. No specimen photographs, contact-position diagrams, measured geometry or actual-size templates.
Official verification resources
- VESA Certified DisplayPort Products — Cables & Adaptors
Look up the exact cable/adapter manufacturer and model in the VESA certified product database. This link or a similar drawing does not certify your cable.
- HDMI Ultra Cable certification label guidance
Use the official cable name and certification label for the exact model; the current HDMI guidance describes standard QR-app verification. A connector picture or generic HDMI version is not product authentication.
These links and a picture do not establish an individual product's certification.
Keep an evidence note
- Source model / output transport
- Converter model / input -> output
- Display model / input + target mode
- Power, software + missing documentation
