VESA Publishes DisplayPort 1.4 Standard

 

VESA has published the new DisplayPort 1.4 Standard, adding Display Stream Compression technology that allows DP 1.4 to drive up to 8K displays or 4K120Hz displays with HDR deep colour. 

Right now DisplayPort 1.2 is the current standard connection for high end monitors, supporting a maximum display resolution//framerate of around 4K60Hz with DisplayPort 1.3, which should start shipping on monitors within a few months, allowing these resolutions and framerates with HDR deep colours also in use.

DisplayPort 1.3 increases the maximum bandwidth link bandwidth of the cable to 32.4Gbps, allowing it to support 5K displays and even 4K120Hz displays.

The new DisplayPort 1.4 standard does not increase the maximum bandwidth of the cable, but it does add a new form of compression called VESA Display Stream Compression (DSC) which allows a virtually lossless 3:1 compression ratio, allowing the cable to carry more detailed visual and audio data using this compression technique.

   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

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.

 

With the demand for high resolution and high refresh rate displays growing it is great to see that VESA is continuing to upgrade their display standard to account for continued improvements in display technology. 

While 4K displays may be very hard to run today, future GPUs will eventually be able to run those kind of resolutions at increasingly high framerates and with HDR (High Dynamic Range) colour, creating a need for higher end display technologies.
