DisplayPort 1.4 vs. VGA
Comparing 2 standards across 10 specifications. 10 key differences identified.
Comparing:
DisplayPort 1.4
VGA
DisplayPort 1.4, released March 2016, kept the same 32.4 Gbps HBR3 link rate as 1.3 but added Display Stream Compression (DSC) 1.2 -- a visually lossless compression scheme that extends the same bandwidth to resolutions like 8K at 30Hz that wouldn't otherwise fit.
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.
