DisplayPort 1.0 vs. HDMI 1.4
Comparing 2 standards across 7 specifications. 7 key differences identified.
DisplayPort 1.0, approved by VESA on May 3, 2006, was the original version of the royalty-free digital display standard. Its High Bit Rate (HBR) mode delivered 10.8 Gbps raw bandwidth across 4 lanes, with hot-plug detection and embedded digital audio built in from the start.
HDMI 1.4, released in 2009, added the HDMI Ethernet Channel, Audio Return Channel (ARC), and stereoscopic 3D video support, plus a 4K mode -- but capped at 24-30Hz, since bandwidth stayed at 10.2 Gbps. The even smaller Type D Micro connector was also introduced.
