DisplayPort: The Advanced Display Connector

What is DisplayPort?

DisplayPort is a high-performance digital interface for transmitting audio and video signals. It was developed to replace older technologies, such as VGA and DVI, and has become one of the most advanced display technologies.

You'll find the DisplayPort interface on desktop computers, laptops, notebooks, tablets, monitors and even some digital televisions.

DisplayPort solutions offer a wide range of advanced features for display and digital signage applications that demand the highest-quality video and audio.

What are the advantages of DisplayPort?

Outstanding Performance Capability

  • DisplayPort 1.2 supports transmission of uncompressed full-color 4K video at 60 Hz
  • Supports multi-channel audio and 3D stereo

Greater Compatibility

  • Supports adapters for legacy displays (VGA, DVI and HDMI)
  • Supports HDCP content protection

Greater Functionality

  • DisplayPort 1.2 supports the connection of multiple displays to a single video output with the ability to stream independent content to each display (multi-stream transport, or MST)
  • Ability with MST to display the same image on each display, extend the desktop across the displays or combine displays to create a video wall (feature set limited to equipment capability)

Greater Versatility

  • DisplayPort and Mini DisplayPort connectors have a small form factor, allowing them to fit compact devices, such as notebooks and tablets
  • DisplayPort can be combined with other standards, such as USB, in a single connector

What is DisplayPort 1.2?

DisplayPort 1.2 represents an upgrade of the original DisplayPort standard (1.1a) with expanded capabilities. It's important to note that not all products that meet DisplayPort 1.2 standards have the entire feature set.

Here are some highlights of the DisplayPort 1.2 standard:

  • Support for 4K video at 60 Hz with increase in color depths and refresh rates
  • Double the maximum data transfer rate of DisplayPort 1.1a
  • Support for multi-stream transport (MST) to multiple displays from a single DisplayPort source
  • Backward compatibility with DisplayPort 1.1a (feature set limited to equipment capability)

What is DisplayPort Alt Mode on USB-C?

With DisplayPort Alt Mode, USB-C connectors and cables have the ability to transmit USB data, DisplayPort video and audio, as well as power signals in combination or individually. Adapters are available to connect DisplayPort over USB-C to VGA, DVI, HDMI and DisplayPort monitors.
