DisplayPort 1.4 vs. HDMI 1.3
Comparing 2 standards across 10 specifications. 10 key differences identified.
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.
HDMI 1.3, released June 22, 2006, roughly doubled maximum bandwidth to 10.2 Gbps and introduced Deep Color (up to 48-bit color depth), lossless audio bitstream support for Dolby TrueHD and DTS-HD Master Audio, and the smaller Type C Mini connector.
