DisplayPort monitor cable
DP (DisplayPort) is a universal standard for the transmission of image and sound signals. Areas of application are in particular the connection of monitors or also TV sets to computers and similar devices. DisplayPort and HDMI are competing standards, although originally for different areas of application. An important technical difference: a connection from DisplayPort to HDMI or DVI is not bidirectional and thus can only be used in one direction, because the DisplayPort connection must be used on the data source side (e.g. at the graphics card) due to the protocol.
DisplayPort v1.1 supports a maximum resolution of 1920x1600 at up to 60Hz and is thus roughly comparable to HDMI High Speed and is still ideally suited for the current market. An important advantage of DisplayPort is the way it locks in place, which, unlike DVI, does not need to be screwed in place, but latches in securely.
DisplayPort v1.2 is the first interface standard that enables 4K resolutions. It achieves up to 3840x2560 at 60Hz, which makes DisplayPort v1.2 predestined for applications with high graphics requirements on a PC or notebook, such as PC games or graphic design. DisplayPort v1.2 uses the daisy chain feature for the first time, which allows monitors connected via DisplayPort to be connected in series and used independently of each other, so that only one DP output is required on the PC/notebook.
DisplayPort v1.3 and v1.4
DisplayPort v1.3 and v1.4 use identical cable material. In addition to the already known daisy chain, the standards are supplemented by HDR support and image compression through colour subsampling (DSC, Display Screen Compression), which are supported by both standards. DisplayPort v1.4, however, adds FEC (Forward Error Correction), an error correction to avoid data loss when using DSC. DisplayPort v1.3 and v1.4 both support a maximum resolution of 5K or 2880p (equivalent to 5120x2880) at 60Hz without the use of compression and DisplayPort v1.4 even supports up to 8K or 4320p (equivalent to 7680x4320) at 30Hz when DSC is used.
