Which technology is primarily used for high-resolution video displays?

DisplayPort is primarily used for high-resolution video displays due to its ability to support higher bandwidths and resolutions compared to other technologies. It can handle multiple channels of audio and video simultaneously, allowing it to transmit high-definition video standards such as 4K and even 8K resolution with deep color and increased refresh rates.

Additionally, DisplayPort supports adaptive sync technologies, which can significantly enhance the viewing experience by reducing screen tearing in fast-moving images, making it a preferred choice in professional and gaming environments where display quality is critical.

While HDMI is also used for high-resolution displays, particularly in consumer electronics, DisplayPort generally provides more robust features and support for higher refresh rates, which is essential for high-end displays and professional-grade applications. Other options like USB and VGA do not provide the same level of video quality or supporting features for high-resolution displays.
