DisplayPort 1.4 supports 8K display via USB Type-C interface
The Video Electronics Standards Association (VESA) finally recognized the DisplayPort 1.4 specification, which the association called DisplayPort 1.3 was recognized as a major update in September 2014. At the same time, this is the first DP standard to support DSC 1.2 (display stream compression) technology. In DSC 1.2, 3:1 visual lossless video stream compression is allowed.
The "Alt Mode" provided by the DP 1.3 standard already supports simultaneous transmission of video and data streams via USB Type-C and Thunderbolt lightning interfaces. The DP 1.4 goes a step further, allowing SuperUSB (USB 3.0) to transmit data while simultaneously transmitting HD video. In addition, DP 1.4 will support 60Hz 8K resolution (7680 x 4320) HDR video and 120Hz 4K HDR video.
"This major update of the DisplayPort standard is critical to the continued growth of adoption of DP and DSC, especially in today's fast-growing digital TV and in-vehicle infotainment." Alan Kobayashi, Chairman of VESA Board of Directors (he is also a R&D manager at MegaChips) ) pointed out that "new applications require higher display resolution, wider color gamut, and increased dynamic range. We believe that the tools provided in this new DP release will make the display quality a leap because it makes good use of it. DSC compression and high quality audio and video content delivery."
Other updates to DP1.4 are as follows:
1. Forward Error Correction (FEC): A part of the DSC 1.2 technology that addresses the moderate fault tolerance of compressed video output to external displays.
2, HDR metadata transmission: Provide support for the current CTA 861.3 standard by using the "secondary data packet" in the DP standard, which is useful for the DP-HDMI 2.0a conversion protocol. In addition, a more flexible metadata packet transmission is provided to support future dynamic HDR.
3. Extended Audio Transmission: This specification covers such as 32-bit audio channels, 1536 kHz sample rate, and all currently known audio formats.
VESA said that DP 1.4 will become the most ideal interface standard for high-quality audio and video transmission needs of high-end electronic equipment.
