What is DisplayPort?

Cable and interface

The DisplayPort cable and the corresponding interface serve as a powerful & flexible DVI successor. DisplayPort is used to connect workstations (PCs) or notebooks to displays with a corresponding interface.


The DisplayPort cable is primarily used to connect PCs and notebooks to a corresponding screen. DisplayPort 2.0 and older interfaces are compatible with the common video interfaces DVI, VGA or HDMI via active or passive adapters.

The origins of DisplayPort 2.0 date back to 2006 and the specification published at that time has been optimised and expanded over the years. Since version 1.3, the DisplayPort cable has supported Multi Stream Transport (MST), stereoscopy (‘3D’), the colour spaces xvYCC, scRGB, Adobe RGB 1998 as well as HDCP 1.3 and DPCP (DisplayPort Content Protection). Version 1.4 also introduced support for Display Stream Compression 1.2 (DSC), forward error correction, HDR10 and the Rec. 2020 colour space. DisplayPort 2.0 (DP 2.0) increases the maximum data rate to 20 GByte/s per lane, which means up to 77.37 GByte/s with four available lanes. This results in a theoretical maximum resolution of 8K (7680×4320) at 120 fps and 30 bit colour depth. The 4:4:4 colour subsampling allows compression that can even support 16K displays.
 

The latest version DisplayPort 2.1 brings some important improvements compared to 2.0, particularly in the areas of range, efficiency and flexibility:

Improved cable compatibility:
DisplayPort 2.1 cables are designed for higher data rates over longer distances, providing more flexibility when using 8K displays or multi-display setups.
More efficient bandwidth utilisation:
DisplayPort 2.1 makes better use of the available bandwidth, especially for connections via USB4 or Thunderbolt. This means that high resolutions and refresh rates can be transmitted without any loss of quality.
More energy efficiency:
Devices with DP 2.1 can operate more efficiently at slower speeds, which means longer battery life for mobile devices.
Extended multi-display support:
The Multi-Stream Transport (MST) feature is optimised for multi-monitor setups, supporting higher resolutions and refresh rates on multiple monitors.
Backwards compatibility:
DP 2.1 remains fully backwards compatible with DP 2.0 and earlier versions, ensuring trouble-free use of older cables and devices.

Overall, DisplayPort 2.1 offers a more stable and flexible solution for demanding high-end displays and multi-monitor setups.

Advantages of the DisplayPort cable  

The DisplayPort cable or interface gives you various advantages over DVI cables and HDMI cables. As it is based on a micro-packet protocol, it allows the standard to be extended easily. The design also supports internal ‘chip-to-chip’ communication, which means that the display panel can be controlled directly. This results in three advantages:
1. Skalierungs- und Kontrollschaltungen entfallen und die Verbindung mit preiswerteren, dünneren Bildschirmen ist möglich, während die Latenzen verringert werden.

2. the standardised interface provides a replacement for internal LVDS connections to notebook panels.
 
3. the interface is compatible with a low-voltage signalling environment used in 45-nanometer CMOS manufacturing.

In addition, both YCbCr and RGB-encoded formats are supported from DP 2.0 onwards. An additional channel is available for USB connections, camera, microphone or a touch-sensitive screen. Thanks to the neat locking mechanism on the DisplayPort cable plug, quick connection is possible without screwing.
Finally, manufacturers generally benefit from DisplayPort as small batches are licence-free, while HDMI annual fees can be up to 10,000 dollars.

InLine DisplayPort Kabel und Adapter

InLine® DisplayPort Cable black gold plated 5m
InLine® DisplayPort Cable black gold plated
This InLine® DisplayPort 1.2 cable meets the standards promoted by the Video Electronics Standards Association VESA. The specification published in 2006 has been optimised and extended over the years. DisplayPort now supports Multi Stream Transport (MST) protocols, 3D, colour profiles xvYCC, scRGB, Adobe RGB 1998, HDCP 1.3 and DPCP (Displayport Con- tent Protection). By expanding the data rate of the AUX channels to 720 Mbit/s, the DisplayPort interface increases bandwidth. The current version 1.3 (as of 2015) increases the maximum data rate to 810 MB/s for each of the 4 channels for a total of 3.24 GByte/s. This translates into a theoretical maximum resolution of 5K (5120 × 2880) at 60fps and 8bit colour depth. The 4:2:0 subsampling of chrominance enables compression, so that UHD-2 displays are supported. Ideal for home theatre entertainment systems, presentations, training sessions or video conferences, and Digital Signage installations.
