DisplayPort 1.2 vs. HDMI 1.0
Comparing 2 standards across 6 specifications. 6 key differences identified.
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.
HDMI 1.0, released December 9, 2002 by a group of seven consumer electronics companies, was the original single-cable digital audio/video connector. It carried up to 4.95 Gbps over TMDS signaling -- enough for 1080p at 60Hz -- replacing separate analog video and digital audio cables with one connector.
