Comparing 2 standards across 14 specifications. 14 key differences identified.

Comparing:
DisplayPort 2.1
DVI

DisplayPort 2.1, announced October 2022, is a certification-level refinement of the DisplayPort 2.0 specification VESA released back in June 2019. Its fastest UHBR20 mode delivers 80 Gbps raw bandwidth -- enough for a single 10K display at 60Hz uncompressed, or multiple high-refresh 4K/8K displays daisy-chained with compression.

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.
