DisplayPort is a standard that is a competitor of HDMI, but has been limitedly used in premium fields until now. DisplayPort, which is smaller than the existing D-SUB or HDMI, was conceived in the early 2000s to replace the existing VGA or DVI like HDMI. Dell, HP, Lenovo. It was supported by VESA groups such as Oculus, Apple, and Nvidia. In fact, most companies that support DisplayPort also support HDMI.
DisplayPort is focused on connecting computers and monitors, while HDMI is focused on connecting TVs and entertainment. DisplayPort is divided into two types: standard size DisplayPort connector and mini DisplayPort connector. This standard is designed so that video and audio can be transmitted simultaneously or with only one of them.
Version 1.0 of DisplayPort appeared in mid-2006. At the time, the standard provided 10.8Gbps bandwidth, which was twice that of DVI. Later versions 1.1 and 1.1a appeared, followed by 1.2 in 2010. DisplayPort 1.3 and 1.4 have expanded bandwidth with 10-year life spans standardized in 2014 and 2016.
The field where DisplayPort has grown the most is games. Nvidia’s G-Sync, which requires DisplayPort, reduces the unnaturalness that occurs when rewriting video frames. The next thing DisplayPort wants to realize is high resolution and high refresh rate.
DisplayPort 2.0 was initially slated for release in 2017, but was postponed to keep pace with the long development period and HDMI standards. DisplayPort 2.0 is a significant evolution from the previous 1.4a. The maximum bandwidth has gone from 25.9Gbps to 77.4Gbps, and the maximum refresh rate is 144Hz at 4K HDR resolution. The maximum resolution for a single display is 15,360×8,460, so Rk 16K 60Hz.
It can also operate 3 4K displays at 90Hz and 2 8K displays at 120Hz. Not to mention the 16K display, but 8K displays are still rare around. This means that DisplayPort 2.0 can be used in any environment in the future.
Of course, backward compatibility is secured, so support for USB Type C or Thunderbolt 3 as well as previous DisplayPort will continue. When the right time comes, DisplayPort 2.0 will be widely used.
If so, do you really need DisplayPort? The HDMI 2.1 standard supports up to 10K resolution, but DisplayPort 2.0 goes beyond that. DisplayPort is also convenient when using multiple displays. The daisy-chain connection helps not only monitors, but also virtual reality.
