What is DisplayPort?

Welcome to another installment of our “Definitions” series, where we take complex technological concepts and break them down into simple terms. Today, we’re diving into the world of DisplayPort, an audio/video interface that is commonly used for connecting computers, monitors, and other display devices. Have you ever wondered what exactly DisplayPort is and how it works? We’ve got you covered!

Key Takeaways:

  • DisplayPort is an audio/video interface used for connecting computers, monitors, and other display devices.
  • It offers high resolution, fast refresh rates, and supports multiple displays daisy-chained together.

The Basics of DisplayPort:

DisplayPort is a digital video and audio interface standard developed by the Video Electronics Standards Association (VESA). It was designed to replace older analog standards like VGA and DVI, offering better performance and flexibility for modern display technology. Here are some key aspects of DisplayPort that you should know:

  1. High Resolution: DisplayPort supports higher resolutions compared to older standards. This means you can enjoy sharper images and more detailed graphics on your display.
  2. Fast Refresh Rates: DisplayPort allows for high refresh rates, which means smoother motion on the screen. This is especially important for gamers and video enthusiasts who demand a fluid visual experience.
  3. Audio Support: DisplayPort not only carries video signals but also supports audio transmission. This eliminates the need for separate audio cables, simplifying your setup.
  4. Daisy-Chaining: One of the unique features of DisplayPort is the ability to daisy-chain multiple displays. This means you can connect multiple monitors together using a single cable, reducing cable clutter and simplifying cable management.
  5. Adapters: DisplayPort is compatible with various adapters, allowing you to connect it to different types of display interfaces, such as HDMI, DVI, or VGA. This versatility makes it a convenient choice for various scenarios.

DisplayPort Versions:

Over the years, DisplayPort has evolved, with new versions offering improved features and capabilities. The most common versions you’ll come across are:

  • DisplayPort 1.1: Introduced in 2006, this version supports a maximum resolution of 2560×1600 pixels and delivers high-quality audio.
  • DisplayPort 1.2: Released in 2009, this version extends the maximum resolution to 3840×2160 pixels. It also introduces Multi-Stream Transport (MST) technology, allowing daisy-chaining of multiple displays.
  • DisplayPort 1.3/1.4: These versions, launched in 2014 and 2016 respectively, further enhance the maximum resolution capabilities, support High Dynamic Range (HDR) displays, and offer increased bandwidth for higher refresh rates and better color depth.
  • DisplayPort 2.0: The latest version, introduced in 2019, brings even more advancements, including support for resolutions up to 16K, higher refresh rates, and improved audio/video data transmission.


DisplayPort is a versatile audio/video interface that offers high resolution, fast refresh rates, and the ability to daisy-chain multiple displays. Its evolution over the years has pushed display technology to new heights, enabling better visual experiences. Whether you’re a gamer, professional designer, or simply someone who appreciates vivid displays, DisplayPort provides the performance and flexibility you need for a seamless setup.

So the next time you come across the term “DisplayPort,” you’ll have a better understanding of its benefits and capabilities. Don’t hesitate to embrace this powerful interface for a truly immersive visual experience!
