Comparing 2 standards across 10 specifications. 10 key differences identified.
Comparing:

VGA
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.
VGA (Video Graphics Array) uses a 15-pin DE-15 D-subminiature connector, introduced by IBM in 1987 alongside the original PS/2 computer. As a purely analog standard with no enforced resolution ceiling, its practical maximum depends on cable and DAC quality, though 2048x1536 @ 85Hz is commonly cited as a practical limit.
