The DP interface, as a successor to DVI, can also be simply understood as an enhanced version of HDMI. It adds support for high-definition audio signal transmission while transmitting video signals, while supporting higher resolution and refresh rate. In the data transmission, DP uses the "micro-packetised" format, and has a high degree of scalability, can continue to add more new content in the future.

DP version development

1.1 Bandwidth 10.8Gbps, maximum support 2560*1600 (2K) resolution (has been basically eliminated)

1.2 Bandwidth 21.6Gbps, up to 4K (4096*2160) 60Hz (most commonly used)

1.3 Bandwidth 32.4Gbps, maximum support 4K (3840X2160) 120hz, 5K (5120X2880) 60hz, 8K (7680X4320) 30hz output.

1.4 Bandwidth 32.4Gbps, up to support 8K level (7680x4320) 60Hz output, 4K can be up to 120Hz. (Latest version)

When we buy DP lines, we will find that there are many types of DP lines, which are divided into DP interfaces and mini DP interfaces developed by Apple according to their size, and there are male-to-male and male-to-female points between them.

Common is DP male-to-male HD cable, generally used as a direct connection for device interconnection, also called video cable, such as computer output terminal to TV input terminal; Male to female is generally used as a data extension line or special equipment connection line, so it is also called a conversion line.
