DisplayPort 1.2 vs. DisplayPort 1.4
Comparing 2 standards across 10 specifications. 10 key differences identified.
Comparing:
DisplayPort 1.2
DisplayPort 1.4
DisplayPort 1.2, released January 7, 2010, doubled maximum bandwidth to 21.6 Gbps via a new High Bit Rate 2 (HBR2) mode, enabling 4K at 60Hz for the first time. Its headline feature, Multi-Stream Transport (MST), lets multiple monitors daisy-chain from a single DisplayPort output.
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.
