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.
