MPEG LA states that the implementation of DisplayPort requires a license and a license payment. It is important to note that these are only CLAIMS. The relevance of these CLAIMS will likely be decided by a U.S. court. Mini DisplayPort (mDP) is a standard announced by Apple in the fourth quarter of 2008. Shortly after Mini DisplayPort`s announcement, Apple announced that it would license toll connection technology. The following year, in early 2009, VESA announced that Mini DisplayPort would be included in the next DisplayPort 1.2 specification. On February 24, 2011, Apple and Intel Thunderbolt announced a successor to Mini DisplayPort, which supports PCI Express data connections while maintaining top-down compatibility with Mini DisplayPort devices.  The Mini DisplayPort port was developed by Apple for use in computer products. It was first announced in October 2008 for use in the new MacBook Pro, MacBook Air and Cinema Display. In 2009, VESA adopted it as the official standard, and in 2010, the specification was merged with the publication of DisplayPort 1.2 in the main DisplayPort standard. Apple granted the specification free of charge to VESA. VESA, the creators of the DisplayPort standard, indicate that the standard can be implemented without a license.
However, in March 2015, MPEG LA issued a press release stating that DisplayPort products manufactured or sold in countries covered by one or more of the MPEG LA licensing pool patents are subject to a royalty rate of $0.20 per unit.   In response to this, VESA updated its DisplayPort FAQ page with the following statement: About VESA The Video Electronics Standards Association (VESA) is an international non-profit standardization association that represents a global network of more than 300 manufacturers of hardware, software, computers, screens and components engaged in the development and promotion of the electronics industry.

DisplayPort 1.0 contains Philips` DPCP (DisplayPort Content Protection) option, which uses 128-bit AES encryption. It also has full authentication and session key. Each encryption session is independent and has an independent locking system. This part of the standard is granted separately. It also adds the ability to check the proximity of the receiver and transmitter, a technique designed to ensure that users do not bypass the content protection system to send data to remote and unauthorized users.

Apple offers a free license for the Mini DisplayPort, but reserves the right to cancel the license if the licensee “initiates a infringement action against Apple.”  A: Once compliance testing is completed and a product has been successful, VESA must submit a report that provides the results of successful tests and shows that the correct methodology has been followed.
