Is There A Difference Between DisplayPort 1.2 And 1.4 Cables?
In the ever-evolving world of technology, new and improved standards are constantly being introduced to enhance the user experience. When it comes to display connectivity, DisplayPort is steadily becoming the go-to choice for high-quality and high-resolution display output. However, with the introduction of different versions like DisplayPort 1.2 and 1.4, users might wonder if there are any differences between the cables used. Let’s dive into the details to understand the disparities and similarities between these two versions.
What is DisplayPort?
DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). It was designed to replace older interfaces like VGA and DVI in order to meet the increasing demand for higher resolutions, refresh rates, and color depths. DisplayPort cables use a connector similar to HDMI but offer additional features like audio and USB data transmission.
DisplayPort 1.2: A Reliable Standard
DisplayPort 1.2 was released in 2009, bringing substantial improvements over its predecessor, DisplayPort 1.1a. It supports resolutions up to 3840 x 2160 pixels at 60Hz, allowing for stunning 4K visuals. With Multi-Stream Transport (MST) technology, DisplayPort 1.2 can drive multiple displays from a single cable, making it ideal for daisy-chaining monitors.
Another essential feature of DisplayPort 1.2 is High Bit Rate 2 (HBR2), which doubles the maximum bandwidth to 21.6 Gbps. This increase in bandwidth allows for improved color depth, refresh rates, and multi-monitor configurations without compromising on image quality.
DisplayPort 1.4: Advancements in Connectivity
DisplayPort 1.4, released in 2016, builds upon the foundation of DisplayPort 1.2 and brings several improvements to the table. Its maximum bandwidth has been increased to 32.4 Gbps, paving the way for 8K resolutions at 60Hz or 4K at a staggering 120Hz. This means smoother visuals and an even more immersive experience for the user.
Furthermore, DisplayPort 1.4 brings support for Display Stream Compression (DSC) 1.2a, enabling even higher resolutions and refresh rates with minimal loss in image quality. It also introduces Forward Error Correction (FEC), which enhances the reliability of data transmission by reducing errors.
Compatibility between DisplayPort 1.2 and 1.4
In terms of physical connectors, both DisplayPort 1.2 and 1.4 share the same shape and size, making them compatible with each other. This means you can use a DisplayPort 1.4 cable with a DisplayPort 1.2 device or vice versa, without any issues.
However, it’s important to note that while a DisplayPort 1.4 cable can be used with a DisplayPort 1.2 device, you won’t be able to take full advantage of the newer version’s enhanced features. The device will still function, but the capabilities will be limited to what DisplayPort 1.2 offers.
Choosing the Right Cable
If you have a high-resolution monitor or plan to upgrade to one, it’s recommended to opt for a DisplayPort 1.4 cable. While DisplayPort 1.2 is still a reliable standard, the advancements in DisplayPort 1.4 offer improved picture quality and refresh rates, especially for demanding applications like gaming or content creation.
When purchasing a DisplayPort cable, ensure that it is certified by VESA’s DisplayPort Compliance Program to guarantee compatibility and proper functioning. This certification ensures that the cable has undergone extensive testing and meets the necessary standards.
In Conclusion
DisplayPort 1.2 and 1.4 cables are both capable of delivering high-quality display output. However, DisplayPort 1.4 offers significant advancements in terms of bandwidth and features, making it the preferred choice for users desiring the best visual experience. So, if you want to make the most of 8K resolutions, improved refresh rates, and other enhanced capabilities, investing in a DisplayPort 1.4 cable is the way to go!
