DisplayPort 1.4 Vs. 1.2 – Which is Better?

A lot has happened in the last few years, especially in the field of technology. DisplayPort is one of those connectors that has undergone a complete revamp from its previous versions. DisplayPort is essential equipment for connecting the PC, PlayStation, and Xbox.


DisplayPort is becoming more prevalent in high-end gaming monitors and home theaters. These cables are more efficient at transferring audio and video data from the PC to the display. Nevertheless, there is always a discussion of comparing different versions of DisplayPort. The effectiveness of these versions and their limitations vary. Despite their similar appearances, there is a fundamental difference between them.

DisplayPort 2.0 is the current version, while DisplayPort 1.2 was released in 2010. The 1.4 version is an upgrade of the previous version, but it does not mean they are fundamentally different. This article will compare the performance and efficiency of DisplayPort 1.2 and 1.4.

What is DisplayPort?

DisplayPort is an effective way to connect audio and video streams from the source to the output. Additionally, they are the interface through which multiple devices can be connected. Thus, data can be transferred between laptops, monitors, PCs, and other workstations.


There’s more to audio and video data transfer than just the DisplayPort. We also have HDMI ports, but that’s another story. DisplayPort has undergone many improvements in recent years, including a noticeable improvement in performance. Therefore, you can play high-resolution games and videos that weren’t possible with old VGA cables.

DisplayPort demonstrates its capabilities as a high-end cable in its number of strengths. Additionally, they have impressive bandwidth and offer a variety of transmission options. In the beginning, TVs replaced old audio and video transmission sources, but with time, they underwent many changes. Comparing DisplayPort 1.4 and DisplayPort 1.2, the older version is still impressive, Display Stream but let’s see what improvements have been made in version 1.4.

In DisplayPort 1.4, there are many improvements over 1.2, but the appearance is largely unchanged. However, in the latest version there are many changes, including This DSC is a lossless compression format that supports higher refresh rates and a wider resolution range.

From top to bottom, DisplayPort 1.4 is a much better specification than DisplayPort 1.2. DisplayPort’s high compression rate and data allowance make it ideal for high-resolution gaming monitors. 1.2 is not far behind in performance, and it still provides good competition to DisplayPort 1.2. It is also the low cost that attracts the users who are looking for an affordable solution for high-resolution gaming.

DisplayPort 1.4 offers greater features than DisplayPort 1.2 due to its higher resolution and refresh rate. 1.4 offers more features and specs than 1.2. DisplayPort 1.2, however, cannot compete with DisplayPort 1.4 in competitive gaming. DisplayPort 1.4 supports 3440×1440 resolution at 250 Hz. DisplayPort 1.2 supports a maximum resolution of 1920*1080 with a refresh rate of 144 Hz. Even DisplayPort 1.4 can achieve a maximum resolution of 3840*2160, which eliminates 1.2 from competition.

Clearly, there is a bandwidth difference between DisplayPort 1.3 and 1.4. DisplayPort 1.2 has a maximum bandwidth of 21.8 GB/sec, which is considerably less than DisplayPort 1.4, which has a maximum bandwidth of 32.42 GB/sec. Even the data rates on both are different. DisplayPort 1.4 supports a data range of 25.94 GB/sec as opposed to 17.2828 GB/sec of DisplayPort 1.2, which is a huge improvement.

Audio channels are also essential to the utility and performance of DisplayPort. DisplayPort 1.4 offers 32 audio channels for superior transmission. In DisplayPort, there are 8 audio channels. Additionally, DisplayPort 1.4 offers HDCP 2.2 protection. Copy protection for 4K content is essential. DisplayPort 1.2 does not support this feature.

In terms of FPS and HDR support, DisplayPort 1.4 is better as it can handle 4K resolution at 60 FPS. Without HDR settings, you can achieve 8K resolution at 60 frames per second. If you are planning to play HD content or high-resolution games at a higher refresh rate, DisplayPort 1.4 is a better choice than DisplayPort 1.2.

Selecting the Right DisplayPort

DisplayPorts are important in modern monitors, and their demand has grown even in the presence of HDMI ports. However, they are more common on computers than on TVs. Different versions of DisplayPort provide HD videos, but their standards are different. DisplayPort comes in four different versions, which are as follows:

When buying DisplayPort, they prefer to buy certified items, as they meet the quality standards. Furthermore, they perform at the same level that these companies advertise on their package, and each type has unique features you won’t find in any other cable.

NVIDIA G-Sync and AMD FreeSync are supported in DisplayPort. Together, these technologies and DisplayPort ensure a tear-free gaming experience. Although this feature is handy, it will only work if your monitor supports the technology.

DisplayPort also has the capability of connecting multiple monitors to a single DisplayPort connection. The utility is very useful since it eliminates the need to use multiple ports in order to connect monitors. The DisplayPort can also be used to connect the USB-C port of laptops.


No doubt, DisplayPort 1.4 has better overall features and usability than DisplayPort 1.2. DisplayPort 1.4 is backward compatible, allowing it to be used on monitors that only support DisplayPort 1.2. Buying DisplayPort 1.4 for older monitors can also save you money as it will be useful when upgrading the hardware. Purchasing a DisplayPort cable from a reputable brand with a compliance certificate is crucial.
