DisplayPort won the PC display slot with a packetized interface no vendor owns
VESA's DisplayPort packetizes the link and embeds the clock, so a thin royalty-friendly cable carries video, audio and data.

那一手
DVI and HDMI carried a separate clock and were bulky in thin laptops, were hard to scale and often licensed.
VESA released DisplayPort 1.0 in May 2006 as a DVI successor built on a packetized micro-packet architecture.
By embedding the clock in the data stream and packing data into micro-packets, it scaled from 1 to 4 lanes and handled high resolutions and refresh rates.
Because it was royalty-friendly and slim, it became the laptop panel and monitor interface, and USB-C's DisplayPort alternate mode spread it further.
为什么管用
- Micro-packet data embeds the clock, so it needs fewer wires and less shielding.
- It is scalable across lanes, so it handles higher resolutions and refresh rates.
- It is a royalty-friendly alternative to HDMI's per-device licensing.
- USB-C's DisplayPort alternate mode made it the default video transport on laptops.
可以搬走什么
A connector standard wins when the protocol is a scalable, low-royalty packet stream rather than a fixed point-in-time analog hack.
后来呢
DisplayPort became the dominant laptop and monitor display interface and the video bearer over USB-C, alongside continuing HDMI use in TVs and consumer gear.
