| HDMI | 2003 | 4096×2160 | 18 Gbps |
| DisplayPort | 2006 | 5120×2880 | 32.4 Gbps |
In conclusion, while VGA is still used in some niche applications, its use has largely been replaced by digital connectivity options. As technology continues to evolve, it’s likely that VGA will become increasingly obsolete, but its legacy will live on as a reminder of the early days of computer graphics.
What Is VGA And How Was It Used In Monitors?
VGA, or Video Graphics Array, is a video interface standard that was widely used in the past for connecting monitors to computers. It was introduced in the late 1980s and became the de facto standard for monitor connectivity in the 1990s and early 2000s.
