DisplayPort (DP) and HDMI are two different types of connections used to transmit audio and video data. DisplayPort was introduced in 2006 and is commonly used for computer displays, graphics cards, and professional IT equipment. On the other hand, HDMI (short for High-Definition Multimedia Interface) was introduced in 2003 and is commonly found on appliances such as television sets, gaming consoles, projectors, and laptops. While both connections support video and audio, there are some differences in their technical specifications and compatibility with certain devices. One notable difference is that HDMI supports audio pass-through, while DisplayPort does not. This makes HDMI a better option for connecting a GPU to an amplifier.

DisplayPort cables can carry audio and video over a single connection
DisplayPort cables are used to connect a computer or other device to a monitor or display device. They can carry audio and video over a single connection, with the audio data transmitted across the main link during the video blanking intervals (short pauses between each line and frame of video data). DisplayPort cables have a unique connector with 20 or more pins and are available in different lengths to accommodate different distances between the source device and the display device. The standard DisplayPort connector (now referred to as a "full-size" connector to distinguish it from the mini connector) was the sole connector type introduced in DisplayPort 1.0. It has a friction lock and an optional mechanical latch.
DisplayPort cables support high-resolution displays, high refresh rates, and the ability to transmit audio and video over a single cable. They are commonly used on computer monitors, graphics cards, and laptops, and are also found in some consumer electronics devices such as TVs and Blu-ray players. DisplayPort cables can also be used to daisy-chain multiple display devices, allowing for a multi-monitor setup without the need for multiple cables.
DisplayPort and HDMI are often compared as they have many of the same features. However, DisplayPort has more of a computer focus, while HDMI has become the standard for connecting televisions and consumer AV products. DisplayPort supports higher display resolutions and refresh rates, making it a popular choice for gamers and professional video editors. DisplayPort Dual-Mode (DP++) will detect when an HDMI or DVI Single-Link monitor is connected and will send HDMI/DVI signals instead of DisplayPort.
DisplayPort to HDMI adapters are available, and these support HDMI audio. It is important to note that the audio driver is responsible for DisplayPort audio, so updating the video driver may be necessary to enable DisplayPort audio.
