VESA Introduces DisplayPort 1.4 standard
VESA Standardization Organization has launched version 1.4 of the DisplayPort standard. The new standard is under the organization first use of VESA’s Display Stream Compression technology.
The latest version of the DSC technique makes data transfer with a compression ratio of 3: 1. VESA claims that the transfer is in the eye lossless, ie without noticeable loss in quality. V isually lossless, such as VESA describes it is a lossy compression method where data loss should not be seen. With true lossless compression There is no loss of data ankle level. The compression method would display port-1.4 are suitable for use in high-end audio and video products. The technique was first intended as a new external interface, but has since been included in other connections, such as USB and c thunderbolt.
Due to the compression of video transmission is the ability to make use of USB-c-connections improved. As a result, both high quality video and USB 3.1 enabled, according to the VESA. At the same time it supports the use of high dynamic range and video 8k resolution through the display port. This standard allows for 8k and 4k at 60Hz with HDR at 120Hz with HDR.
Furthermore, the new standard with forward error correction, by which the resistance to the loss of data that is needed is implemented for the transmission of compressed video to external screens. Also, DisplayPort 1.4 HDR metadata transport and function. This uses secondary data packet, which is integrated into the display port standard to support the current CTA 861.3 standard. This is among other things used for the conversion of the DisplayPort protocol to the HDMI 2.0a protocol. In addition, the support is intended to provide for future dynamic HDR standards. Finally Expands DisplayPort 1.4, the options for audio transmission from. The new extension provides opportunities as 32 audio channels and a sample rate of 1536kHz, and may include all known types of audio filesViewing:-148
