DisplayPort Version 1.3, approved in September 2014, enhances transmission bandwidth to 32.4 Gbit/s with the new HBR3 mode, enabling higher-resolution displays and faster refresh rates. This accommodates 4K UHD at 120 Hz, 5K at 60 Hz, or 8K at 30 Hz.

The standard supports driving multiple displays and includes Dual-mode for DVI and HDMI adapters. Thunderbolt 3 was intended to include DisplayPort 1.3 but ended up with version 1.2. Adaptive Sync remains optional. DisplayPort Version 1.4, released in March 2016, maintains HBR3 as the highest mode and introduces support for features like Display Stream Compression, HDR10 metadata, and expanded audio channels.
