Direct Answer
DisplayPort 1.4, released March 2016, kept the same 32.4 Gbps HBR3 link rate as 1.3 but added Display Stream Compression (DSC) 1.2 -- a visually lossless compression scheme that extends the same bandwidth to resolutions like 8K at 30Hz that wouldn't otherwise fit.

Display Stream Compression Changed the Math
DisplayPort 1.4 kept the same 32.4 Gbps HBR3 link rate introduced in the little-adopted DisplayPort 1.3, but added Display Stream Compression (DSC) 1.2 -- a visually lossless compression scheme that lets the cable carry resolutions its raw bandwidth couldn't otherwise support. Without DSC, DisplayPort 1.4 tops out at 4K (3840x2160) at 120Hz uncompressed; with DSC, 8K at 30Hz becomes possible over the same physical link, though higher-refresh 8K claims from some vendors depend on more aggressive compression than the baseline spec guarantees.
DisplayPort 1.4 remained the mainstream high-bandwidth DisplayPort standard for several years, widely adopted on PC graphics cards and monitors before DisplayPort 2.0/2.1's much larger bandwidth increase arrived in 2022.
