DisplayPort won the PC display slot with a packetized interface no vendor owns

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.

Packetize the link and drop the clock wire

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.

A connector standard wins when the protocol is a scalable, low-royalty packet stream rather than a fixed point-in-time analog hack.

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.
