Displayport 1.2 vs 1.4 - Differences & Similarities

Navigating the world of display technology can be daunting especially when presented with choices like DisplayPort 1.2 and DisplayPort 1.4.

Did you know, for instance, that while both connectors serve to deliver high-definition video and audio from a computer to a monitor, each has its unique capabilities?

This article illuminates their differences – from release dates, bandwidths and data bit rates to resolution capacities – empowering you with the information required to make an informed choice based on your usage needs.

What is DisplayPort?

DisplayPort is a digital display interface primarily used to connect a video source like a computer or gaming console, to a display device such as a monitor, TV, or projector. It’s developed by the Video Electronics Standards Association (VESA) and can transmit both audio and video signals.

DisplayPort offers high resolutions with higher refresh rates making it the preferred choice for high-end monitors and graphics cards.

With its ability to deliver 4K resolution at 60Hz, DisplayPort 1.2 still has more bandwidth than most HDMI standards further solidifying its position in the market.

However, technology doesn’t stand still.

The introduction of DisplayPort 1.4 took capabilities even further with increased maximum total bandwidth reaching up to 32.40 Gbps and data rate peaking at 25.92 Gbps supporting even larger resolutions while maintaining high refresh rates of over 120Hz at native 4K resolution using HDR10 standard compatibility for more vibrant visuals.

Key Differences between DisplayPort 1. 2 and 1. 4

Release dates

DisplayPort 1.2, an innovation delivered in 2009, revolutionized the scene with its superior bandwidths and refresh rates outperforming older standards like DVI and VGA.

Fast forward to seven years later, DisplayPort 1.4 was launched in 2016 introducing striking upgrades from its predecessor: it not only embraced progressive monitor resolutions up to 8K but also boasted higher refresh rates.

This newer version of DisplayPort enabled users to experience visuals with absolute clarity and unparalleled smoothness on their displays.

Interestingly, three years after the introduction of DisplayPort 1.4, the industry saw another significant advancement with the emergence of DisplayPort 2.0 in 2019 that further expanded support for leading-edge resolutions.

Resolutions and refresh rates

DisplayPort 1.2 and 1.4 significantly differ in their support for resolutions and refresh rates, with the latter coming on top. DisplayPort 1.2 supports up to 4K (3840×2160 pixels) at a refresh rate of 60Hz, providing the necessary bandwidth for most mainstream uses today.

Stepping into higher-end territory, DisplayPort 1.4 offers enhanced capabilities including support for stunning visuals up to a resolution of 8K (7680×4320 pixels) at a sedate refresh rate of up to 30Hz or more dynamic displays like gaming monitors featuring full HD (1080p) with an astounding refresh rate up to 240Hz or even high-resolution monitors sporting a resolution of 1440p at a smooth-ticking rate of upto240Hz; all these revolutionary specs meeting every professional and gamer’s needs alike!

Notably, it also includes the feature “Display Stream Compression” that enables high HDR quality content without compromising color depths resulting in visually stunning imagery making this version stand distinctively ahead compared to its predecessor – The Port cabled Displayport version- DP1.2.

Bandwidths and data bit rates

DisplayPort 1.2 and 1.4 differ in terms of bandwidths and data bit rates.

DisplayPort 1.2 has a maximum total bandwidth of 21.6 Gbps, allowing it to support mainstream resolutions and refresh rates with ease.

On the other hand, DisplayPort 1.4 offers a higher maximum total bandwidth of 32.40 Gbps, which allows for larger volumes of data to be transmitted at faster speeds.

This means that DisplayPort 1.4 can handle more demanding display requirements such as higher resolutions and refresh rates, making it ideal for gamers or professionals who need the best possible visual experience on their monitors or displays.

Overall, while both versions are compatible with most devices and cables, the increased bandwidth and data bit rate capabilities of DisplayPort 1.4 ensure smoother performance when dealing with ultra-high-definition content like 5K or even 8K resolutions at higher refresh rates.

Color resolutions

DisplayPort 1.4 offers better color performance, supporting up to 30-bit color depth for displays that require more accurate and vibrant colors.

This allows for a wider range of colors to be displayed, resulting in a more immersive visual experience.

On the other hand, DisplayPort 1.2 supports up to 24-bit color depth, which still provides excellent color accuracy but may not be as advanced as what DisplayPort 1.4 can offer.

So if you’re someone who values precise and lifelike colors on your monitor or TV screen, opting for a device with DisplayPort 1.4 compatibility would be a wise choice.

Maximum audio channels

DisplayPort 1.4 is the clear winner when it comes to maximum audio channels.

While DisplayPort 1.2 only supports up to 8 audio channels, DisplayPort 1.4 takes it to a whole new level by supporting a whopping 32 audio channels!

This means that with DisplayPort 1.4, you can experience immersive sound quality like never before, whether you’re gaming, watching movies, or listening to music.

The increased number of audio channels in DisplayPort 1.4 allows for more detailed and precise surround sound effects, making your overall audio experience much richer and more realistic.

So if you’re an avid gamer or a movie enthusiast who values high-quality sound as much as stunning visuals, opting for devices that support DisplayPort 1.4 will undoubtedly elevate your entertainment experience to new heights.

High-dynamic-range (HDR)

DisplayPort 1.2 and 1.4 both support high-dynamic-range (HDR) technology, which enhances the visual experience by providing greater contrast and color accuracy.

HDR allows for a wider range of colors and more detailed shading, resulting in richer and more lifelike images on your display.

With DisplayPort 1.4, you can enjoy HDR10 standard support, ensuring that your content looks stunning with vibrant colors and deep blacks.

Whether you’re gaming or watching movies, HDR compatibility on DisplayPort ensures an immersive viewing experience like never before.

Display Stream Compression (DSC)

Display Stream Compression (DSC) is an important feature in DisplayPort 1.4 that allows for the transmission of higher resolution and refresh rates without sacrificing image quality.

It works by compressing the video data before sending it over the cable, reducing the amount of bandwidth required. With DSC, DisplayPort 1.4 can handle stunning visuals like 8K resolution at up to 60Hz or even 4K at a smooth refresh rate of 120Hz.

This means gamers and content creators can enjoy incredibly detailed graphics without any loss in visual fidelity or performance.

DSC is just one of many reasons why DisplayPort 1.4 is a superior choice for those seeking high-quality display connectivity options.

Performance difference between DisplayPort 1. 2 and 1. 4

DisplayPort 1.4 brings significant performance improvements compared to DisplayPort 1.2.

With a maximum total bandwidth of 32.40 Gbps and a maximum data rate of 25.92 Gbps, DisplayPort 1.4 allows for higher resolution and refresh rates than its predecessor.

It supports stunning 4K visuals at up to 120Hz, lower resolutions exceeding 400Hz, and even impressive 5K and 8K resolutions.

One standout feature of DisplayPort 1.4 is the integration of Display Stream Compression (DSC) version 1.2, which enables a wider range of resolutions and refresh rates without sacrificing quality or bandwidth requirements.

This means that you can experience smooth gameplay or enjoy high-resolution content without worrying about compromising visual fidelity.

Additionally, DisplayPort 1.4 embraces the High-Dynamic-Range (HDR)10 standard, which enhances color contrast and delivers more vibrant images with better brightness control in supported displays.

Another improvement over DisplayPort 1.2 is the enhanced audio capabilities offered by DP 1.4, supporting up to an impressive total of thirty-two in-line audio channels for an immersive sound experience alongside your high-quality video output.

Overall, if you’re looking for top-of-the-line performance from your display setup or graphics card for gaming or multimedia purposes, upgrading to DisplayPort is highly recommended – especially considering how popular it has become among desktop computing enthusiasts due to its superior capabilities compared to HDMI standards.
