Can I use a DisplayPort 1.4 on 1.2? – The Ultimate Guide

It’s a common question asked by those who are looking to upgrade their displays or simply want to know more about the capabilities of their current set up. The short answer is, in most cases,

yes, you can!

For example, you can connect a DisplayPort 1.4 video port to a DisplayPort 1.2 video port using an adapter.

Or If you have two DisplayPort 1.2 video ports, you can use a DisplayPort 1.4 video cable to connect them.

You can also use a DisplayPort 1.2 video cable to connect two DisplayPort 1.4 video ports, allowing you to create a stunning visual display, however, The video resolution and FPS will be limited by the quality of the video cable. 

However, as with anything technology related, there are a few things you need to take into account before making the switch. In this article, we’ll go over everything you need to know about using a displayport 1. 4 on 1. 2.

What is DisplayPort 1.4?

The DisplayPort 1.4 standard was first introduced in March 2016, providing high resolution and refresh rates. Although it didn’t introduce any new transmission modes and the available bandwidth and data rate did not increase as well, DisplayPort 1.3 maintained its strong showing. The maximum total bandwidth for DisplayPort 1.4 is 32.4Gbps, and the maximum total data rate is 25.92Gbps. With enough bandwidth to handle a 4K UHD stream at up to 120Hz with 24-bit/px color, or a 5K display at up to 60Hz with 30-bit/px color, that gives it the power to produce stunning visuals. Even though it supports 8K video, the hefty bandwidth demands limit it to 30Hz.

What is DisplayPort 2.0?

DP 2.0 was launched in 2019 and it has added quite the substantial amount of features to this new standard. For the true bleeding edge enthusiasts, DisplayPort 2.0 supports 8K @ 60 Hz monitor resolutions, as well as 10K @ 60Hz and 16K @ 60 Hz monitor resolutions. It boasts a transfer rate of 77.37 Gbps and HDR10 support. Plus, All DisplayPort 2 devices will require DSC support, which is a standard for lossless image compression. Some manufacturers ignore this standard, however, which can lead to subpar image quality. DisplayPort 2.0 also offers the option of adaptive sync.

DisplayPort 1.4 vs. 1.2: What’s the difference?

DP 1.2 vs DP 1.4

You might be wondering what the difference is between DisplayPort 1.2 and 1.4. After all, they’re only 2 versions apart, So, surely their specifications can’t be that same, right?

Let’s jump into what each of the two DisplayPort versions have to offer in response to all your questions!

The raw data

The four lanes of DisplayPort 1.2 offer a maximum total bandwidth of 21.6 Gbps, and a maximum total data rate of 17.28 Gbps. In comparison, the four-lane structure of DisplayPort 1.4 remains the same, but the maximum total bandwidth has been increased to 32.40 Gbps., and maximum total data rate to 25.92 Gbps.

So, Which DisplayPort version comes out on top in a head-to-head comparison? The latest DisplayPort 1.4 technology provides a noticeable margin of improvement.

Resolutions, refresh rates, and more

In 2010, DisplayPort 1.2 ushered in a new era of high-end data transmission, with support for features like adaptive synchronization and panel-self-refresh. The resolution and refresh rate support were improved, opening up the option of 5K resolution at up to 30Hz, 4K at up to 75Hz, and 1080p at up to 240Hz – DisplayPort connection has reached previously impossible standards.

DisplayPort 1.4 is a much greater step forward. This monitor is the perfect choice for gamers who want the best visuals and performance, supporting 1440p resolution at up to 240Hz and 4K at up to 120Hz Like DisplayPort 1.3, it is designed to deliver the best possible gaming experience. This monitor also supports 5K resolution at up to 60Hz, and even 8K resolution at 30Hz, making it perfect for even the most demanding tasks.

Which DisplayPort Version is Better?

DisplayPort 1.4 is the clear winner when it comes to maximum total bandwidth, maximum total data rate, resolutions, and FPS. DisplayPort 1.4 is the clear winner when it comes to improvements. Even if your current equipment only supports DisplayPort 1.2, a quality DisplayPort 1.4 cable is still a great choice. But why stop there? Get a cable that supports DisplayPort 1.4 and future-proof your setup.

What’s next?

DisplayPort 1.4 is the best high-end cable for years. And We recommend using a DisplayPort 1.4 cable over its alternatives for your video needs – especially if your ports are 1.4 as well.

If you want to use DisplayPort 1.4 on 1.2, just use the video cable with the highest version and connect the ports.
