What Is Displayport?

What Is Displayport?

DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). It is designed to transport video and audio from a computer or other source device to a display, like a monitor, TV, or projector.

Key Features of DisplayPort

  • High Resolution and Refresh Rates: DisplayPort supports high resolutions such as 4K, 5K, 8K, and beyond, along with high refresh rates, making it suitable for gaming monitors, professional graphics, and detailed video work.
  • Multi-Stream Transport (MST): DisplayPort can support multiple displays from a single output using MST, which allows for daisy-chaining multiple monitors together or using a hub.
  • Audio and Video: It can carry both audio and video signals simultaneously. DisplayPort cables can also carry USB signals, allowing for USB data streams to be sent over the same cable.
  • High Bandwidth: The latest version, DisplayPort 2.0, dramatically increases the bandwidth capability, supporting up to 77.37 Gbps, which can handle resolutions up to 16K with HDR at 60Hz.
  • Adaptive Sync: DisplayPort supports Adaptive Sync technologies, such as AMD's FreeSync and NVIDIA's G-Sync, which help eliminate screen tearing and stuttering by synchronizing the display's refresh rate with the output of the graphics card.
  • Backward Compatibility: DisplayPort maintains backward compatibility with previous versions, although using new features may require cables and devices that support the higher specifications.

DisplayPort Versions

Over the years, DisplayPort has evolved through versions that have increased the capabilities of the standard. Some notable versions include:

  • DisplayPort 1.2: Added support for Multi-Stream Transport, higher resolutions, and increased bandwidth.
  • DisplayPort 1.3: Increased bandwidth to support 4K displays at 120Hz and 8K displays at 60Hz.
  • DisplayPort 1.4: Introduced support for HDR and 8K resolution at 60Hz with HDR using Display Stream Compression (DSC).
  • DisplayPort 2.0: Announced in 2019, it greatly increased bandwidth to support higher resolutions and refresh rates, including 16K at 60Hz with DSC.

Connector Types

DisplayPort connectors come in two main sizes:

  • Standard DisplayPort (DP): The most common size used on PCs, laptops, and monitors.
  • Mini DisplayPort (mDP): Smaller port commonly found on laptops and some graphics cards. It's also used by Apple's Thunderbolt interface, which is compatible with Mini DisplayPort.


DisplayPort is primarily used in the computing industry, where its ability to support high resolutions and refresh rates is particularly valuable for gaming and professional applications. It's also found in some consumer electronics, although HDMI is more prevalent in home entertainment systems.

Cables and Adapters

DisplayPort cables are often labeled by their version, though any DisplayPort cable of decent quality should support features such as 4K resolution and beyond. Adapters are available to convert DisplayPort to HDMI, DVI, and VGA, providing flexibility for connecting to non-DisplayPort displays.

In sum, DisplayPort is a versatile, high-performance interface that has become the preferred choice for many high-end computing and gaming setups due to its ability to support the latest video standards and technologies.
