Key Differences Between Mini DisplayPort and USB-C

1. Physical Design

a. Mini DisplayPort:

Rectangular with a slightly indented side.

Smaller than a standard DisplayPort connector.

b. USB-C:

Oval-shaped, symmetrical, and reversible (can be inserted either way).

More compact and modern compared to Mini DisplayPort.

2. Functionality

a. Mini DisplayPort:

A dedicated video and audio output port.

Transmits high-definition video and audio signals.

Does not support data transfer, power delivery, or other functionalities.

b. USB-C:

A multi-purpose port for video, data, audio, and power.

Can act as a DisplayPort, HDMI, or other video output (via adapters) when using DisplayPort Alternate Mode.

Supports data transfer speeds (up to 40 Gbps with Thunderbolt 3 or 4).

Can deliver power for charging devices (up to 100W in some cases).
