VESA Announces Display Port 1.4, Ready For 8K 60 Hz and 4K 120 Hz HDR Displays- Runs Over Fast USB Type-C Connector
VESA (Video Electronics Standards Association) has announced that they have published the latest Display Port 1.4 audio/video standard. The Display Port 1.4 standard is a major update to the Display Port 1.3 version which was released back in September 2014. The new standard takes advantage of new features and supports higher resolution displays with faster refresh rates.
VESA’s Display Port 1.4 Standard Will Usher New Era For 8K 60 Hz and 4K 120 Hz Displays
VESA’s Display Port 1.4 will use the latest USB Type-C and Thunderbolt connectors allowing laptops to utilize higher resolution displays that support the latest standard. The new standard aims to drive high res displays. VESA has stated that the new standard aims to support 8K displays which will become popular in the coming years as more manufacturers launch such products and at effective prices for the consumer markets. The 4K scene in the display world has gained quite a lot of traction. PC Gaming is just one of the markets where the high-end / enthusiast space is booming and more gamers want to get a taste of 4K resolution monitors.
Display Port 1.4 will be building upon the foundations of Display Port 1.3 which doubled the link bandwidth of Display Port 1.2 to 32.4 Gb/s. The new standard is meant to leverage from High-definition Video, SuperSpeed USB and also facilitates HDR (High Dynamic Range) displays. Display Port 1.4 is capable of driving 8K at 60 Hz (HDR Deep Color) and 4K at 120 Hz (HDR Deep Color) displays along with other key features that include the following:
- Forward Error Correction – FEC, which overlays the DSC 1.2 transport, addresses the transport error resiliency needed for compressed video transport to external displays.
- HDR meta transport – HDR meta transport uses the “secondary data packet” transport inherent in the DisplayPort standard to provide support for the current CTA 861.3 standard, which is useful for DP to HDMI 2.0a protocol conversion, among other examples. It also offers a flexible metadata packet transport to support future dynamic HDR standards.
- Expanded audio transport – This spec extension covers capabilities such as 32 audio channels, 1536kHz sample rate, and inclusion of all known audio formats.
In addition to the high resolution support, DP 1.4 takes advantage of VESA’s Display Stream Compression (DSC) technology. DSC version 1.2 transport enables up to 3:1 compression ratio and has been deemed, through VESA membership testing, to be visually lossless. Together with other new capabilities, this makes the latest version of DP ideally suited for implementation in high-end electronic products demanding premier sound and image quality.
“This significant update to the DisplayPort standard is vital to continued growth of adoption for both DP and DSC, particularly in such fast-growing markets as digital television and automotive infotainment,” via VESA
said VESA Board Chair Alan Kobayashi, fellow and executive R&D management for Smart Connectivity Group at MegaChips Technology America.
“New applications are demanding displays with better resolution, wider color gamut, and increased dynamic range. Consumers and others are also recognizing the value and ease-of-use associated with running multiple displays on one interface, which is another area we addressed in this new release with MST improvements. We believe the tools provided in this new DP standard release will enable a quantum leap forward in display quality, which leverage DSC compression along with transport of high-quality audio and video content.” via VESA
As far as this news is concerned for gamers, current GPUs support Display Port 1.2 which allows 4K 60 Hz frame capabilities. AMD has announced that their upcoming Polaris GPUs will feature support for DP 1.3 functionality. The new functionality will allow up to 5K 60 Hz display support and at the same time, AMD will be focusing HDR as a key enabler for displays with their next generation graphics cards. NVIDIA will also be delivering support on their upcoming Pascal GPUs for the latest display standards to allow their GPUs to run higher resolution display monitors with faster refresh rates.
