Mini DisplayPort (mDP)
The Mini DisplayPort (mDP) is a compact version of the DisplayPort interface, introduced by Apple in 2008. Designed for transmitting high-definition video and audio, mDP quickly became a standard for modern laptops, desktops, and monitors due to its small size and high performance. It supports resolutions up to 4K at 60Hz and is compatible with multiple audio channels, making it suitable for connecting to high-resolution displays, projectors, and home theater systems. Mini DisplayPort was later adopted by the VESA (Video Electronics Standards Association) to broaden its industry application.

One of the key advantages of Mini DisplayPort is its ability to carry both video and audio signals, eliminating the need for separate cables. It also supports daisy chaining, allowing multiple monitors to be connected to a single output port. This feature is particularly beneficial for professional setups requiring extended desktop environments. Additionally, mDP is backward compatible with DisplayPort devices, ensuring versatility and wide adoption across various hardware platforms.

Mini DisplayPort was used in Apple products, including the MacBook, iMac, and Mac Pro, before being replaced by USB Type-C and Thunderbolt interfaces in later models. Despite this shift, Mini DisplayPort remains relevant in certain devices and adapters, serving as a reliable option for connecting legacy hardware. Its adoption in standards like Thunderbolt 1 and Thunderbolt 2 further cemented its importance in high-speed, high-quality video transmission.
