The Evolution of DisplayPort: From 1.4 to 2.1

The journey of DisplayPort technology has been marked by significant advancements, with the introduction of DisplayPort 2.1 being the latest milestone. This new iteration supersedes its predecessor, DisplayPort 2.0, offering enhancements primarily in bandwidth and efficiency. The key differentiator between DisplayPort 2.1 and 1.4 lies in their bandwidth capacities and encoding techniques. While DisplayPort 1.4 utilized the 8b/10b encoding system, resulting in a maximum bandwidth of 32.4 Gbps, DisplayPort 2.1 leaps ahead with a 128b/132b encoding scheme. This change drastically increases efficiency and boosts the total data rate to 77.37 Gbps in UHBR 20 transmission mode.

Comparing DisplayPort 2.1 and HDMI 2.1

When juxtaposed with HDMI 2.1, DisplayPort 2.1 demonstrates superior performance, particularly in terms of bandwidth. DisplayPort 2.1 can support higher refresh rates and resolutions without relying on compression, a feat HDMI 2.1 can match only with DSC. However, HDMI 2.1 does offer unique features like ARC and eARC, which are absent in DisplayPort.

The Practical Applications of DisplayPort 2.1

The vast bandwidth of DisplayPort 2.1 paves the way for groundbreaking applications in gaming monitors, VR/AR headsets, and professional displays. Its ability to support resolutions up to 16K at 60Hz with HDR and 10-bit color (using DSC) is particularly notable. This makes it ideal for high-end gaming and professional graphics work, where color accuracy and image clarity are paramount.
