DisplayPort and HDMI are both interfaces that transmit high-definition video and audio, but what does a DisplayPort do compared to HDMI? COMPARE.EDU.VN helps you understand the key differences between these two standards, including their purpose, form factor, function, and use cases, ensuring you can make the right choice for your setup. By exploring their distinct characteristics, we aim to simplify the decision-making process and clarify video output options and display connectivity.
1. DisplayPort and HDMI: An Overview
DisplayPort is a digital video and audio interface developed by the Video Electronics Standards Association (VESA). It connects display devices like desktop monitors, laptops, and projectors to video sources such as CPUs. DisplayPort has two main types: standard and mini. The Mini DisplayPort transmits signals just like the standard version.
HDMI (High Definition Multimedia Interface) transfers high-definition video and audio through a single cable. It’s commonly used in commercial and home settings to connect devices like Blu-ray players, set-top boxes, and gaming consoles to TVs, as well as CPUs to computer desktops. HDMI is a ubiquitous option for AV connectivity and high resolution video.
2. What Is DisplayPort?
Over the past decade, DisplayPort has become popular, especially in high-end desktop monitors and graphics cards. It features an asymmetric connector with an L-shaped header. While DisplayPort isn’t as universally present as HDMI, it’s a crucial hardware standard with several capabilities as a connector and cable technology. DisplayPort is designed for high performance gaming monitors and professional displays.
DisplayPort works like other data connection standards. You plug each end of the cable into the supporting slots on the relevant devices. Most modern devices automatically detect each other and complete the configuration. For older devices, you might need to use the display device’s control panel to manually choose the DisplayPort input and set the resolution and refresh rate. Automatic detection and configuration simplifies user setup.
Technically, DisplayPort uses packetized data transmission, similar to motherboard PCI-Express ports and Ethernet cables. This means it transmits micro packets of data with an embedded clock signal. These transmissions are highly efficient and support higher resolutions and refresh rates. Packetized data transmission increases efficiency.
DisplayPort features an open and expandable design, allowing for improvements and newer versions over time. These factors make DisplayPort one of the most important display standards of the past decade. Continuous improvement and innovation have kept DisplayPort relevant.
3. What Is HDMI?
HDMI, or High-Definition Multimedia Interface, is a data transmission standard that connects a data source, like a CPU or set-top box, to an output device, such as a television, projector, desktop monitor, laptop, or speaker. HDMI has become a go-to option for AV connectivity.
Electronics manufacturers developed HDMI to create a universal standard for linking devices. The primary goal was to improve connectivity standards and meet the demands of high-definition video content by enabling higher data throughput. The HDMI cable features a small, handy connector and enhanced support for embedded audio. Small connector designs and enhanced audio support are key advantages.
Since its development in 2002, HDMI has been widely adopted across devices. Today, HDMI is as common as USB for consumer devices like televisions and computers. Broad adoption makes HDMI a ubiquitous choice.
Various types of HDMI cables cater to different use cases. The Standard HDMI cable is the most common variant, compatible with satellite TV resolutions up to 720p and 1080i, with a throughput capability of up to 5Gbps. Standard HDMI provides compatibility with common resolutions.
A standard automotive HDMI connector has the same specifications as the regular cable but is designed for in-car video displays and other industrial applications. It’s reinforced with extra shielding to minimize interference from nearby electrical systems. Automotive HDMI is designed for industrial applications.
Other HDMI connector variants provide even higher throughput, making them more viable for media at higher resolutions. High-speed HDMI connectors support speeds up to 10.2Gbps and can handle 4K video resolutions. High-speed automotive HDMI cables feature the same specifications but are optimized for automotive and industrial applications. High-speed HDMI supports 4k video resolutions.
Other types of HDMI include premium high-speed HDMI and ultra-high-speed HDMI. Ultra High-Speed HDMI supports 8K video alongside a transfer speed of 48Gbps and support for HDR and HDMI 2.1. Ultra high speed hdmi delivers enhanced performance.
HDMI cables can generally support built-in Ethernet, allowing numerous HDMI-supporting devices to connect over a shared Ethernet connection using a router.

4.2. Purpose
| DisplayPort | HDMI | |
|---|---|---|
| Main | DisplayPort is a digital interface designed to ensure seamless video and audio delivery using a single cable. It links a display to a data source (like a monitor to a graphics card) and delivers video and sound data for processing and output. DisplayPort cables and connectors are usually seen in their “full-sized” variant, which features 20 pins on a double-L-shaped connector. Its asymmetrical form factor increases seamless physical connectivity compared to more uniform ports such as HDMI and USB. The smaller “Mini DisplayPort” variant is also used. | HDMI connectors come in four sizes—standard, mini, micro, and automotive—each serving a unique purpose. Standard HDMI connectors or Type A HDMI connectors are typically used by corporations and personal users. They connect source devices such as gaming consoles and Blu-ray players to monitors and televisions. Mini HDMI connectors, also called Type C HDMI connectors, are created for more specific device use cases, such as DSLR cameras and tablet computers. Micro HDMI connectors or Type D HDMI connectors are seen in even smaller and more portable devices. |
| Usage | Apart from its data transmission capabilities, DisplayPort sees use on other technology platforms for its form factor. Intel Thunderbolt 3 supports DisplayPort version 1.2. DisplayPort may not be commonly found on mainstream devices such as gaming consoles, monitors, graphics cards, and televisions. However, it is common in devices priced higher than average, such as gaming monitors and high-end graphics cards. For instance, AMD’s RX 5700 Navi cards and Nvidia’s RTX 2000 GPUs both come with DisplayPort connectors. | Automotive or Type E HDMI connectors are rarely found in everyday use and generally seen in automotive and industrial applications. Type B HDMI connectors are also used but minimally. This is because the Type B HDMI connector was also introduced alongside the original standard in 2002 to transmit dual-link DVI video; however, once HDMI 1.3 was introduced, the throughput offered by a single link surpassed that of the dual-link connection. Type B HDMI is still a specification retained on record. |
4.3. Form Factor
| DisplayPort | HDMI | |
|---|---|---|
| Design | The standard DisplayPort connector comes with 20 pins and offers only two sizes. The first size variant is the standard DisplayPort connector. The second is a smaller alternative, “Mini DisplayPort,” designed primarily for Apple devices, featuring the same form factor as the Apple Thunderbolt port. Regular DisplayPort connectors also feature a locking mechanism, a hook or lock system that keeps the cable in place to minimize the risk of accidental disconnection. The optimum data transmission is approximately 3 meters of cable length. | Unlike DisplayPort, HDMI comes with numerous form factors. The most commonly seen HDMI variant is Type A, a standard in almost every modern-day television and computer. HDMI Type C is a standard for tablet computers and smaller laptops. Type D is used in smartphones and tablets, and Type E is customized for automobile and industrial applications. All these variants come with 19 pins. The HDMI standard does not specify exact dimensions and capabilities in terms of cable length. |
| Pins | The unused Type B (extended pin HDMI) variant, primarily made for DVD applications, comes with 29 pins. | Unlike DisplayPort, which features a locking mechanism in the standard form factor, only Type E HDMI (Automotive) offers a locking mechanism. Other HDMI connectors are just a pull away from disconnection. However, they insert firmly into ports and require a reasonably strong pull to be removed and don’t just fall out of their sockets. |
4.4. Function
| DisplayPort | HDMI | |
|---|---|---|
| Features | The DisplayPort standard allows multiple monitors to function concurrently on a single connection. It supports stable performance and HD resolution up to 1920×1200 when four displays operate on a single connection, as long as the maximum bandwidth is not exceeded. DisplayPort is technically capable of supporting CEC functions, though this feature is seldom seen. | All HDMI variants do not inherently offer multiple monitor functionality and would generally require a converter DisplayPort hub to do so. HDMI, created as a consumer electronics standard, comes with CEC support, allowing HDMI to control an entire entertainment system with a single remote control. The latest HDMI iteration offers a special HEC function, allowing built-in HDMI Ethernet channel functionality. |
| Addition | DisplayPort does not support Ethernet functionality or audio return signals, making it incapable of commanding audio systems. | This gives users up to 100Mbps internet speed over HDMI connections and allows audio control functions. HDMI is also capable of linking devices to the internet without the need for additional connection lines. |
4.5. Use Cases
| DisplayPort | HDMI | |
|---|---|---|
| Application | DisplayPort is the standard of choice for specific use cases when it comes to desktop monitors. DisplayPort supports G-Sync and FreeSync and offers technical advantages for setups that feature older-generation hardware. One use case where DisplayPort is the clear winner is configurations requiring multi-display support. | HDMI enjoys widespread usability and more commonplace use cases than DisplayPort. Many modern-day output devices offer direct compatibility solely with HDMI. Gaming consoles, such as Sony PlayStation and Microsoft Xbox, are excellent examples of this. HDMI is ideal for use cases requiring Ethernet support and is better suited for entertainment applications. |
| Benefits | DisplayPort cables that correspond to the equivalent HDMI release offer higher maximum throughput, making them ideal for higher refresh rates and frames per second (FPS) in gaming applications. | The additional support for popular audio signals like Dolby also gives HDMI an edge over DisplayPort in more popular use cases. CEC support means HDMI is better suited for entertainment applications. |
5. Making the Right Choice
Choosing between HDMI and DisplayPort depends on the specific use case and the technical specifications of the display and video card included in the setup. The newest version of DisplayPort (version 2.0) offers an extremely high resolution and refresh rate.
For devices that offer a choice between DisplayPort 1.2 and HDMI 2.0, the latter may be preferred for HDR support. For instance, if a user wishes to enjoy the features of HDMI 2.0, the monitor and video card must both support HDMI 2.0 and not an earlier version. Regardless of the standard, users must check the compatibility of every link in the device chain before choosing a cable. This will offer an optimum combination for the best possible performance. Understanding your specific use case is crucial.
