What is DisplayPort? Displayport port features across versions

Today, right in the article below, TechtipsNReview.com shares with you the concept of What is DisplayPort??

1. What is Displayport?

DisplayPort (DP) is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). The interface is mainly used to connect a video source to a display device such as a computer monitor, and it can also carry audio, USB, and other forms of data.

DisplayPort is designed to replace VGA, FPD-Link, and digital video interfaces (DVI). This interface is backward compatible with other interfaces, such as HDMI and DVI, through the use of active or passive adapters.

DisplayPort was the first display interface based on pacing data transfer, a form of digital communication found in technologies such as Ethernet, USB, and PCI Express. So in item 1. we have finished sharing information about What is DisplayPort?? Next comes the DisplayPort port classification.

2. DisplayPort standards

Devices laptop, macbookHigh-end to high-end graphics cards are integrated with DisplayPort ports in two main forms: Mini DisplayPort and Thunderbolt. So you also need to read through the concept of what DisplayPort port is? in item 1.

3. DisplayPort feature by version

– DisplayPort version 1.0 – 1.1.: Allows a maximum bandwidth of 10.8 Gbit/s (8.64 Gbit/s data rate) over the standard 4-lane main link for devices implementing link layers alternatives such as optical fiber, allowing longer reach between source and display without signal degradation, although alternative implementations are not standardized.

– DisplayPort version 1.2: The most significant improvement of the new version is to double the effective bandwidth to 17.28 Gbit/s in High Bit Rate 2 (HBR2) mode, allowing increased resolution, refresh higher scale and greater color depth. Other enhancements include multiple independent video streams (daisy-chain connection to multiple displays) called multi-stream transport, utility for stereoscopic 3D, increased AUX channel bandwidth (from 1 Mbit/s to 720). Mbit/s), more color spaces including xvYCC, scRGB and Adobe RGB 1998, and global timecode (GTC) for audio/video synchronization under 1 μs.

– DisplayPort version 1.3: This standard increases the overall transmission bandwidth to 32.4 Gbit/s with the new HBR3 mode of 8.1 Gbit/s per lane (up from 5.4 Gbit/s with HBR2 in version 1.2), for a total data throughput of 25.92 Gbit/s after factoring in the 8b/10b encryption overhead. This bandwidth is enough for a 4K UHD (3840×2160) display at 120Hz with 24bit/px RGB color, a 5K (5120×2880) display at 60Hz with 30bit/px RGB color, or an 8K UHD (7680×4320) display at 30Hz with 24bit/ px RGB color. Using multi-stream transport (MST), one DisplayPort port can drive two 4K UHD (3840×2160) displays at 60Hz or up to four WQXGA (2560×1600) displays at 60Hz with 24bit/px RGB color.

– DisplayPort version 1.4: Can support 8K UHD (7680×4320) at 60Hz or 4K UHD (3840 × 2160) at 120Hz with 30bit/px RGB color and HDR. 4K at 60Hz 30bit/px RGB/HDR can be achieved without DSC. On monitors that do not support DSC, the maximum limit is unchanged from DisplayPort 1.3 (4K 120Hz, 5K 60Hz, 8K 30Hz).

– DisplayPort 2.0 version: Link speed from 8.1 to 10.0 Gbit/s, up 24%. This will increase the total bandwidth from 32.4 Gbit/s to 40.0 Gbit/s. So, you need to understand what is the concept of Displayport port?

4. Notes on using DisplayPort

Before choosing to buy a DisplayPort connector, you should learn and carefully see if your device is compatible with which DisplayPort version to ensure efficiency and not be wasted when buying. Currently, on the market, there are many different DisplayPort cables such as DisplayPort 1.1, 1.2, 1.4 that support basic needs such as HD1080, 2K, 4K, ….

Here we share exactly the information related to What is DisplayPort?? Hope it will help you in the process of using it.
