Display port

DisplayPort is a digital display interface standard developed by the Video Electronics Standards Association (VESA) to connect a video source to a display device. It supports high-resolution, high-refresh-rate, and multi-monitor configurations.

What does Display port mean?

Display Port (DP) is a digital display interface standard developed by the Video Electronics Standards Association (VESA) to Transmit high-definition video and audio signals from a source Device to a display device. It employs a packetized Data Transmission method that ensures reliable and efficient data transfer.

DP offers a wide range of features, including support for high resolutions up to 8K, high refresh rates up to 240Hz, and high color depths up to 10 or 12 bits per color channel. It also supports various color spaces, such as sRGB, Adobe RGB, and BT.2020, providing accurate and vibrant colors. Additionally, DP supports multi-monitor setups and enables daisy chaining of multiple displays using a single cable.

Applications

Display Port is widely used in various applications, including:

  • Computer monitors: DP is the primary interface for connecting high-resolution monitors to computers, allowing for seamless and high-quality display of graphics and videos.

  • Projectors: DP is commonly used to connect projectors, providing high-quality video and audio for presentations, movies, and other content.

  • Televisions: Some televisions feature DP inputs, enabling direct connection from source devices for superior image and Sound quality.

  • Gaming consoles: DP is supported on many gaming consoles, providing high refresh rates and low latency for smooth and immersive gameplay.

  • Virtual reality (VR) headsets: DP is essential for VR headsets, delivering high-resolution video and audio streams with minimal latency for an immersive virtual experience.

History

Display Port was first released in 2006 as a replacement for the older VGA and DVI interfaces. It has since undergone several revisions, each bringing significant improvements in performance and capabilities:

  • DisplayPort 1.x: Released in 2006, it offered resolutions up to 2560 × 1600 at 60Hz and supported HDCP encryption.

  • DisplayPort 1.2: Released in 2010, it introduced support for 4K resolutions at 30Hz and higher refresh rates at lower resolutions.

  • DisplayPort 1.3: Released in 2014, it doubled the Maximum bandwidth to 32.4 Gbps, allowing for 4K resolutions at 120Hz and 8K resolutions at 60Hz.

  • DisplayPort 1.4: Released in 2016, it introduced support for 8K resolutions at 120Hz, HDR content, and compressed formats like DSC.

  • DisplayPort 2.0: Released in 2019, it significantly increased the maximum bandwidth to 80 Gbps, enabling support for 16K resolutions at 60Hz, DSC 1.2a compression, and variable refresh rates up to 144Hz.
