DisplayPort 1.2 vs. DVI
Comparing 2 standards across 11 specifications. 11 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.
DVI (Digital Visual Interface) comes in five variants -- DVI-D (digital only, 19 or 25 pins), DVI-I (digital + analog, 23 or 29 pins), and DVI-A (analog only, 11 pins) -- with single-link supporting up to 1920x1200 @ 60Hz and dual-link up to 2560x1600 @ 60Hz.
