What is VGA? Although many people use the term "VGA" casually to mean any modern high-resolution display or video card , the term VGA — which stands for "Video Graphics Array" — has a very specific technical meaning. Developed by IBM, it was first introduced in , and was used to describe a display with a resolution of x , 16 colors there were a few other modes it could display as well.
It was, at the time, a considerable improvement over previous color graphics options. Traditional VGA Although it would be a few years before IBM released another formal video standard, other video card manufacturers quickly began producing cards that could support higher resolutions and color depths than IBM's VGA standard.
When printing pictures, the minimum recommended resolution is pixels per inch. At this output resolution, the VGA picture would be 2. The biggest advantage of the VGA setting is the small file size. This allows for taking more pictures, and faster transfers using less bandwidth. For pictures intended to be viewed online, VGA resolution is usually sufficient. Desktop monitors display resolution is usually less than pixels per inch, so at a 4" x 6" size, a high resolution picture will not appear any sharper than a VGA picture.
Some mobile devices have higher resolution screens, but as the screen is smaller the end result is the same. There have been a number of "smartwatches" for kids in recent years.
