Mini DP Male to DP Female 转接头
Mini Displayport Male to Displayport Female Converter
DisplayPort is the first display interface to rely on packetized data transmission similar to other data communication protocols such asEthernet,USB, andPCI Express. It supports both external (box-to-box) and internal (laptop LCD panel) display connections, and unlike DVI/HDMI and LVDS standards where differential pairs are fixed to transmitting RGB pixels and a clock signal, the DisplayPort protocol is based on smalldata packetswithclock embedded. The use of data packets also allows for DisplayPort to be extensible, meaning additional features can be added over time without significant changes to the interface itself.[6]
The DisplayPort connector supports 1, 2, or 4 differential data pairs (lanes) in a Main Link, each with a raw bit rate of 1.62, 2.7, or 5.4 Gbit/s per lane with self-clock running at 162, 270, or 540 MHz. Data is8b/10b encodedwhere each 8 bits of information are encoded with a 10 bit symbol. So the effective data rates after decoding are 1.296, 2.16, and 4.32 Gbit/s per lane (or 80% of the total).
Both video and audio signals are optional; a Displayport signal can be used to transport audio-only content, video-only content, or both audio and video simultaneously. The video signal path supports 6 to 16 bits percolor channel, and the audio path supports up to 8 channels of 24 bit 192 kHz uncompressedPCMaudio which can encapsulate compressed audio formats in the audio stream.[7]A bi-directional, half-duplex auxiliary channel carries device management and device control data for the Main Link, such as VESAEDID,MCCS, andDPMSstandards. In addition, the interface is capable of carrying bi-directional USB signals.[8]
The DisplayPort signal is not compatible withHDMIorDVI. However, dual-mode ports marked with a DP++ logo can transmit single-linkHDMIandDVIsignals through DisplayPort cabling; this requires passive external adapters which convert to the higher signal levels used by DVI/HDMI. Dual-link DVI and analog VGA are supported through powered adapters which perform active conversion[7](seeCompatibility with HDMI/DVIbelow).
