DISPLAYPORT 1.4 BANDWIDTH LICENSE

The certification indicates the maximum bit rate supported, i.e. However, transmission performance may be limited according to the certification the cable receives. Together, they account for the transmission of audio, video and auxiliary data – in effect, you don’t need a separate cable for each thing.īy default, we find in the connector four sets of tracks (or, in English, lanes) that respond for the transmission of audio and video data, besides auxiliary channels that carry complementary information to the transmission:Īs a rule, every DisplayPort cable should work with DisplayPort-compatible devices, regardless of version. Internally, the connector is shaped by 20 pins (or contacts). For starters, the DisplayPort socket has a small “cut-out” on one side to prevent incorrect connection. DisplayPort connector and cableįrom a distance, the DisplayPort connector might even pass for the USB-A (traditional) connector or the HDMI connector, but they’re quite different from each other. It is also possible to associate a connection of the type with the USB and Thunderbolt standards. The standard supports, for example, HDCP to protect transmitted content from piracy (you’ll learn more about this later).

To that end, the technology has been developed to be royalty-free, meaning that manufacturers don’t have to pay any kind of license to implement it in their devices.Īs if that wasn’t enough, DisplayPort also stands out for its integration with other technologies or specifications. We’re talking about a standard that, at least to some extent, has emerged to replace older video connection technologies such as VGA, DVI and S-Video. There’s no need to have a wire or a connector for each thing, therefore. This work is important because it is necessary to ensure that the technology meets parameters such as performance (including here transmission quality), robustness and interoperability between different devices, otherwise the existence of the standard would not make sense.īesides images – in high resolution, by the way – a DisplayPort connection can transmit audio, simultaneously. The entity is responsible, to this day, for the definitions, standardization and promotion of DisplayPort. The technology was officially introduced in 2006 by the Video Electronics Standards Association (VESA). HDCP and DPCP What exactly is DisplayPort?ĭisplayPort is a digital video interface standard that connects devices that display images (such as monitors and TVs) to computers and, eventually, other equipment.
