== DisplayPort vs. HDMI ==
DisplayPort and High-Definition Multimedia Interface (HDMI) are separate standards for transmitting digital video and audio from a source device to a display.<ref name="ref1" /> While both serve a similar function, they possess key differences in their features, typical applications, and the business models of their governing bodies. DisplayPort is managed by the Video Electronics Standards Association (VESA), a consortium of manufacturers.<ref name="ref2" /> HDMI is developed by the HDMI Forum and licensed by HDMI Licensing Administrator, Inc.<ref name="ref3" />

=== Key Distinctions ===

==== Use Cases and Market Adoption ====
The distinct feature sets of DisplayPort and HDMI have led to their adoption in different markets. DisplayPort is frequently found on desktop computers, laptops, and high-performance monitors.<ref name="ref4" /> Its support for higher bandwidth and Multi-Stream Transport makes it suitable for multi-monitor and high-refresh-rate gaming setups.

HDMI is the standard interface for consumer electronics such as televisions, A/V receivers, Blu-ray players, and video game consoles.<ref name="ref4" /> Features like the Audio Return Channel (ARC) are designed for home theater environments, simplifying the connection between a TV and a sound system.

==== Technical Features ====

'''Multi-Stream Transport (MST)'''
A feature exclusive to DisplayPort, MST allows a single port on a source device to send out multiple independent video signals. This enables users to connect multiple monitors in a "daisy-chain" sequence or through an MST hub, with each monitor displaying unique content. This capability is not present in the HDMI standard, which generally requires a separate port for each connected display.<ref name="ref4" />

'''Audio Return Channel (ARC and eARC)'''
HDMI includes the Audio Return Channel (ARC) feature, which allows a single HDMI connection to transmit video to a television and also send audio "upstream" from the TV back to an A/V receiver or soundbar. This eliminates the need for a separate audio cable. The newer Enhanced Audio Return Channel (eARC) standard, part of the HDMI 2.1 specification, offers significantly higher bandwidth to support uncompressed, high-quality audio formats. DisplayPort does not have a comparable built-in audio return function.<ref name="ref4" /><ref name="ref1" />

==== Licensing ====
The business models for the two standards differ. VESA offers DisplayPort as a royalty-free open standard, though membership in VESA is required to access the newest specifications. Manufacturers do not pay a per-device fee to include DisplayPort. In contrast, companies that manufacture products with HDMI must become licensed adopters, which involves paying an annual fee and a per-unit royalty for every device sold.<ref name="ref3" />
