Video Graphics Array (VGA)
The most common standard that VESA defined, which is still in use today, is the Video Graphics Adapter, or VGA standard.
Video manufacturers grabbed hold of the VGA standard and created many extensions of the standard, while still supporting true VGA mode.
This mode supports 16 colors at 640x480 resolution, or 256 colors at 320x200 resolution. All VGA compliant video cards support VGA mode.
The Windows operating system comes with a standard VGA compatible driver that will work with any VGA compliant video card.
The advantage of this is if you install a new video card and the driver that comes with the card does not work in Windows, the operating system will load the standard VGA driver automatically.
This way you will still be able to see recognizable output through the monitor.
