Early computer is not popular, display applications mainly in the TV interface for analog signals AV terminal and S terminal, 1990 computer began to develop, computer screen and TV slowly become the two mainstream of the display market, the resolution of the requirements of the increase from VGA to DVI and HDMI, from analog to digital signals, and the development of HDMI is mainly led by the brand of TV video and audio-related fields, one is connected to the antenna, set-top box, player, or game console for long-distance viewing, and the other is connected to the computer for close use. One is connected to antennas, set-top boxes, players, or game consoles for long-distance viewing, and the other is connected to computers for close-range use. Driven by the differences in functions and requirements, VESA proposed the DisplayPort architecture in 2006, and HDMI became the two main interfaces for screens, but HDMI remains the main interface for TVs.
The launch of DisplayPort 1.3 brought the data bandwidth to 32.4Gbps, and forced HDMI to increase the bandwidth upwards to support higher resolution and update rate, so HDMI 2.1 (48Gbps) was launched in 2017; USB-IF and VESA, after obtaining Intel's authorization of Thunderbolt technology, launched DisplayPort 2 on Type C interface launched DisplayPort 2.0 (80Gbps), which can support up to 16K@60Hz, and can be transmitted simultaneously with the data stream of USB4, so that DisplayPort is widely used in the computer periphery, but the adoption rate of the ecosystem in the TV field is still low, mainly because VESA and HDMI belong to different ecosystems and organizations, behind which there are The main reason is that VESA and HDMI belong to different ecosystems and organizations, and there are different major manufacturers behind them, so it is no longer simply a technical and functional consideration, but the influence of major manufacturers on the market.
