What is DisplayPort? Version Of Display Port & It's Future

What is DisplayPort? Version Of Display Port & It’s Future: DisplayPort you may hear this word many time in various Apple Mac devices, New Graphics card and many other various places. As HDMI interface has become more popular than previous display DisplayPort is also making its place for higher resolution display.

DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA) an organization which has a membership with various other industry companies. VESA also promote many new technologies earlier like Super VGA which has a resolution about 600p. Talking about DisplayPort which is an interface which was made to primarily connect a video source to a display device, alongside with Video it also transfers Data, Audio, and various other things. DisplayPort other previous technology like VGA or DVI which was designed by VESA. DisplayPort is also compatible with ports like VGA, DVI, and HDMI which separate adapter. So what is DisplayPort, Why DisplayPort and What the benefit of it is the major question which we will discuss here so let’s get started

Display Port Technology, It’s Working And Advantages:

What Is DisplayPort?:

DisplayPort is same as HDMI as both of them were used for Display Connectivity. DisplayPort made its first appearance in 2006. As now there so much less adoption of DisplayPort is possible as same time HDMI is also transforming. While there are some other improvements which you’ll not find in HDMI as this Port is capable of transferring data which means that technology like Ethernet, USB, and PCI Express also works. It allows both internal and external display connection. DisplayPort is capable of transferring both Video and Audio but it can be able to transfer simultaneously or separate optionally. The video signal path can have six to sixteen bits per color channel and the audio path can have up to eight chances of 24-bit 192 kHz uncompressed. DisplayPort received many improvements over it life spans and currently working on DisplayPort 1.4.

Version Of Display Port:

1). Version 1.0 to 1.1:

  • DisplayPort was first approved by VESA on 3 May 2006. Version 1.1a is also released on 2 April 2007. DisplayPort port is capable of having a max bandwidth of 8.64 Gbit/s which is more than HDMI. DisplayPort 1.1 allows devices to implement alternative kink layers such as fiber optic.

2). Version 1.2:

  • This version was approved on 22 Dec 2009. Which bring most significant changes to bandwidth as it reaches 17.28 Gbit/s in High Bit Rate 2, which is equal to today’s HDMI 2.0. As this change allow industry to increase display resolution, bring new color code like Adobe RGB, scRGB and various other. Apple also features Mini DisplayPort into their Mac devices as that port is also capable using Thunderbolt.
  • DisplayPort 1.2a also bring many new features like AMD FreeSync and other things to the industry like Adaptive sync.

3). Version 1.3:

  • DisplayPort Version 1.3 was approved on 15 Sept 2014. This increases the bandwidth way beyond imagination as 32 Gbit/s with new HBR3 made feature 8.1 Gbit/s per lane. Data throughout also increases to 25.92 Gbit/s.  For the support, DisplayPort is capable of displaying 4K at 120Hz while 5K at 60 Hz it also support 8K UHD display at 30Hz. This port also gets the support of Thunderbolt 3 which is also done a phenomenal data transfer.

4). Version 1.4:

  • DisplayPort 1.4 was released on March 1, 2016, as many industries new GPU from AMD and Nvidia which support Polaris and Pascal receptively. While there is no bandwidth increase in this version but added support of stream compression 1.2 (DSC), Forward Error Correction, HDR 10 extension defined. It also brings improvements to a resolution like 4K with 10-bit color and HDR, 8K UHD also gets improvement with 60 Hz fresh rate with HDR.
  • DSC is a visually lossless encoding technique with up to 3:1 compression ratio.

So these are the version which DisplayPort comes with but why is only display is also major questions.

Why DisplayPort?:

  • Durability: DisplayPort is upgraded new version after VGA and DVI Ports as it looks a like HDMI with one side cut. DisplayPort has got many new advancements over VGA and DVI as it does not include pins so wear and tear is less.
  • Supports: VGA and DVI have very low bandwidth but DisplayPort has changed the way. DisplayPort also brings multiple monitor support, high color support, wide color gamut, DisplayPort also bring many new things like 3D and VR. Their much more various things in which DisplayPort changes the way.
  • Better Than HDMI: DisplayPort also advances HDMI as its Bandwidth is way beyond HDMI, HDMI transfer video, and audio on the single way but DisplayPort has control on both. There are many future displays in the world like 8K which support DisplayPort rather than HDMI. HDMI royalties are very heavy as compared to DisplayPort.
  • Ports Diversity: There are many port option available for DisplayPort like Mini DisplayPort, Micro DisplayPort, DDM, Display Stream Compression, eDP, iDP, PDMI, wDP, SlimPort, DisplayID, DockPort, USB Type-C. Among all these Type-C will become more successful in future for adoption as industry is moving toward one port standard.

So as time passes technology changes and DisplayPort will also change to some other new port. So I think you may learn something interesting things today. Hope you see in next article.
