Because the standard has evolved over the years, not all DisplayPort cables will work properly at the latest speeds. The original Display 1.0-1.1a spec allowed for RBR (reduced bit rate) and HBR (high bit rate) cables, capable of 5.18 Gbps and 8.64 Gbps of data bandwidth, respectively. DisplayPort 1.2 introduced HBR2, doubled the maximum data bit rate to 17.28 Gbps and is compatible with standard HBR DisplayPort cables. HBR3 with DisplayPort 1.3-1.4a increased things again to 25.92 Gbps, and added the requirement of DP8K DisplayPort certified cables.

In June 2019, with the release of version 2.0 of the DisplayPort Standard, VESA announced that the DP8K certification was also sufficient for the new UHBR10 transmission mode. No new certifications were announced for the UHBR13.5 and UHBR20 modes. VESA is encouraging displays to use tethered cables for these speeds, rather than releasing standalone cables onto the market.

DisplayPort 1.1 added optional implementation of industry-standard 56-bit HDCP ( High-bandwidth Digital Content Protection) revision 1.3, which requires separate licensing from the Digital Content Protection LLC. [8] :§1.2.6 Displayport cables are high performance digital cables used to connect computer monitors, laptops, and other devices to display screens. It supports the transmission of high-resolution video and audio signals, making it a popular choice for connecting devices that require high-quality display output. A display port is always male on the cable and female on the device. All DP cables have the same basic layout and wiring and will support any feature including audio, daisy-chaining, HDR and DSC.

The DisplayPort main link is used for transmission of video and audio. The main link consists of a number of unidirectional serial data channels which operate concurrently, called lanes. A standard DisplayPort connection has 4 lanes, though some applications of DisplayPort implement more, such as the Thunderbolt 3 interface which implements up to 8 lanes of DisplayPort. [39] :4 The maximum limits for the RBR and HBR modes are calculated using standard data rate calculations. [50] For UHBR modes, the limits are based on the data efficiency calculations provided by the DisplayPort standard. [51] :§3.5.2.18 All calculations assume uncompressed RGB video with CVT-RB v2 timing. Maximum limits may differ if compression (i.e. DSC) or Y′C BC R 4:2:2 or 4:2:0 chroma subsampling are used.
