DisplayPort 2.1 launched in 2022 and is the latest version of the DisplayPort interface standard, while DisplayPort 1.4 launched in 2016 is the most commonly used previous version. They differ in several aspects, including bandwidth, resolution, refresh rate, and features. In this video were going to look at what separates them and whether it's a big upgrade.

One of the main differences between DisplayPort 2.1 and 1.4 is their bandwidth. DisplayPort 2.1 offers a higher maximum bandwidth of 77.4 Gbps compared to DisplayPort 1.4's maximum bandwidth of 32.4 Gbps. This allows DisplayPort 2.1 to support higher resolutions, refresh rates, and colour depths.

Another difference is their maximum resolution and refresh rate. DisplayPort 2.1 can support up to 8K resolution (7680 x 4320 pixels) at 60 Hz or 4K resolution at 144 Hz. DisplayPort 1.4, on the other hand, can support up to 8K resolution at 30 Hz or 4K resolution at 120 Hz. This means that DisplayPort 2.1 can handle higher-resolution displays and smoother gameplay than DisplayPort 1.4.

Finally, DisplayPort 2.1 also supports Multi-Stream Transport (MST) and HBR3, which allow for multiple displays to be daisy-chained together and for high-bandwidth audio and video signals to be transmitted simultaneously over a single cable. These features are not available in DisplayPort 1.4.
In conclusion, DisplayPort 2.1 is a significant improvement over DisplayPort 1.4 in terms of bandwidth, resolution, refresh rate, and features. It is capable of supporting higher-resolution displays, smoother gameplay, and more advanced features than DisplayPort 1.4, making it a better choice for high-end displays and gaming setups.
