High-bandwidth digital display connector common in IT and professional AV.

Common Uses in AV
- PC/workstation displays
- Digital signage (daisy-chain support via MST)

Key Considerations
- Latching connector (push-release) — more secure than HDMI
- Multi-Stream Transport (MST) allows daisy-chaining displays
- Mini-DP and USB-C Alt Mode are electrically identical
