DisplayPort 1.4 vs DisplayPort 2.0 [Major Differences]

VESA ( Video Electronics Standards Association) has released a new specification – the DisplayPort 2.0 in 2019. This newer version provides great features. This is the upgraded version of the previous DisplayPort 1.4. This DisplayPort 2.0 is much better than the 1.4. Let’s see the difference in their features. The Differences between these two cables are given in the format of their specifications. Let’s go through them and know each spec of the cables and judge which one is better. But let’s first find out what DisplayPorts are.

DisplayPort

A cable that is developed by a consortium of PCs that is used as the cable for a computer is known as DisplayPort. It’s a digital display interface. It is developed by VESA. It supports high resolution with several connector pins.

DisplayPort 1.4

DisplayPort 1.4 was launched in 2016. This DisplayPort has many benefits. It has many outstanding features, which are mentioned below –

Resolution

The DisplayPort has a resolution of 8K, DSC 1.2 (Display Stream Compression), and HDR (High Dynamic Range). It can support a resolution of 8K in 60Hz and 4K in 120Hz frequencies. This produces enhanced resolution.

Bandwidth

DisplayPort 1.4 supports a bandwidth of 32. 4Gbps maximum.

Bit rate

This DisplayPort 1.4 transmits 8.1Gbps over 4 lanes.  The maximum bit rate is 4Gbps.

Color Resolution

DisplayPort is the first port that has the DSC 1.2 version. This version supports 4:2:0 and 4:2:2 codes. This doesn’t allow the pixels to be converted into RGB. This enhances the resolution by having compressed pixels. 16 bits per color is supported by Version 1.2. This gives us in-depth content.

Port type

DisplayPort 1.4 can be built over a USB type – C port due to the presence of a video transport compression system. This super-speed USB allows high-resolution videos. Moreover, HDR and 8K are provided over DP cable or USB Type C. This is done through DisplayPort Alt mode.

Power savings

Forward error correction is also an important feature of DisplayPort 1.4. This doesn’t allow any errors to occur in the videos during transport. This also allows power saving.

Highlighted Features of DisplayPort 1.4

  • HDR meta transport is a noticeable feature of DisplayPort 1.4.
  • Expanded audio transport over 32 channels and 1536Hz sample rates are important features of DisplayPort 1.4.

This was all about the specifications of DisplayPort 1.4. It provides us with its best specs that attract users.

DisplayPort 2.0

When the DisplayPort 1.4 was in demand in the market, the company introduced the DisplayPort 2.0 with more specifications and advantages. DisplayPort 2.0 fulfills the expectations of the people. Let’s see some specs of this DisplayPort.

Resolution

According to the statements of VESA, this DisplayPort 2.0 is the first DisplayPort that can support 8K resolution at a refresh rate of 60Hz.

Bandwidth

The DP 2.0 can triple its bandwidth maximum up to 80Gbps.

Bit rate

Over the 4lanes, DisplayPort 2.0 has introduced three different bit rates of resolutions, each of them – 10Gbps,13. 5Gbps and 20Gbps. In this DisplayPort, VESA tried to introduce passive cables which support UBHR 10 (UBHR – Ultra High Bit Rate). This delivers a bit rate of 40Gbps.

Color resolution

 It also has a full-color resolution of 4:4:4. For HDR-10, it also provides 30 bits per pixel.

Port type

DisplayPort 2.0 is provided with a Type – C connector which gives a better experience. SuperSpeed USB and high-resolution videos can be operated simultaneously due to wider bandwidth.

The Power Savings

Panel Replay Feature also gets important in DP 2.0. This allows power saving in small operating machines or PCs with higher resolution.

Highlighted Features

According to VESA, the DisplayPort 2.0 has the following resolution features: 

Single display resolution

  • 16K display at 60Hz and 30bpp 4:4:4 HDR (and DSC)
  • 10K display at 60Hz and 24bpp 4:4:4. (without compression)

Dual Display Resolution

  • Two 8K displays at the rate of 120Hz and 30bpp 4:4:4 HDR (with DSC)
  • Two 4K displays at the rate of 144Hz and 24bpp 4:4:4(without compression)

Triple Display Resolution

  • Three 10K displays at the rate of 60Hz and 30bpp 4:4:4 HDR (with DSC)
  • Three 4K displays at the rate of 90Hz and 30bpp 4:4:4 HDR(without compression)

Are the specifications of DisplayPort 2.0 up to level?

  • DisplayPort 2.0 is the only cable that meets all the requirements of the people. It has complete quality control over the cables.
  • Advanced cable tester V2 supports a variety of cables including HDMI and DisplayPort. This tester can even test DisplayPort 2.0. It can be used to test the standard level and quality of the cable. This tester tests the pins that are to test the continuity (openings or shorts). With Cable Tester V2 you can quickly and thoroughly check the cables.  This device is designed to fit factory and line settings.
  • This device enables us to know the level of each cable.

These were some of the differences between the features of the two DisplayPorts – DisplayPort 1.4 and DisplayPort 2.0. Both of them have their own specs. But the newly launched DisplayPort 2.0 has more advanced features than the DisplayPort 1.4.
