What is the maximum refresh rate supported by dp1.2?

dp1.2 supports up to 144Hz refresh rate; the refresh rate refers to the number of times the electron beam scans the image on the screen repeatedly; the higher the refresh rate, the better the stability of the displayed image; the refresh rate is high or low Will directly determine its price, but since the refresh rate and resolution are mutually restrictive, only a display with a high refresh rate at high resolution can be called excellent performance.

What is the maximum refresh rate supported by dp1.2?

dp1.2 supports a maximum refresh rate of 144Hz.

The refresh rate refers to the number of times the electron beam scans the image on the screen repeatedly. The higher the refresh rate, the better the stability of the displayed image (picture). The refresh rate will directly determine its price, but since the refresh rate and resolution are mutually restrictive, only a monitor with a high refresh rate at high resolution can be called excellent performance.

Note that although its calculation unit and vertical scanning frequency are both Hz, these are two completely different concepts. The 75Hz screen refresh rate is the most basic standard set by VESA for flicker-free. The 75Hz here should be a standard that can be achieved in all display modes.

DisplayPort is the first display communication port to rely on packet data transmission technology. This packetized transmission technology can be found in Ethernet, USB, PCI Express and other technologies. It can be used for both internal and external monitor connections. Unlike past standards that required a fixed transmission timer signal in the differential pair at each output, the DisplayPort protocol is based on small data packets called micropackets.

Main Features

DisplayPort can be used to transmit audio and video simultaneously, each of which can be used independently without the other transmission. The video signal path can have 6 to 16 bits per color channel, and the audio path can have up to 8 channels of 24-bit 192 kHz uncompressed PCM audio, or a compressed audio format can be encapsulated in the audio stream.

A bidirectional, half-duplex auxiliary channel carries device management and device control data for the primary link, such as VESAEDID, MCCS and DPMS standards. Additionally, the communication port is capable of carrying bidirectional USB signals.
