The article discusses the origin of the term “Super VGA” which was created by VESA in the late 1980s, raising IBM’s VGA display standard from 640×480 to 800×600. This led to the addition of more resolutions under the VGA/SVGA label with no cap on the number of colors that can be displayed due to the technology being analog.
The Evolution of Screen Resolution: From VGA to Super VGA
As technology advances and we demand higher quality displays for our devices, it’s important to understand the history and evolution of screen resolution. One notable milestone in this evolution is the introduction of Super VGA, which expanded the capabilities of VGA displays.
What is Super VGA?
Super VGA, or SVGA, is a display technology that expanded on the standard VGA (Video Graphics Array) resolution of 640×480. It was created in the late 1980s by the Video Electronics Standards Association (VESA) as a response to the increasing demand for higher quality displays.
The original SVGA resolution was 800×600, which was a significant improvement over VGA. Later, even higher resolutions were introduced under the SVGA label, including 1024×768 and 1280×1024.
How Does Super VGA Work?
Unlike digital display technologies such as LCD and LED, VGA and SVGA are analog technologies. This means they transmit electrical signals that the display then translates into colors and images.
While there is no cap on the number of colors that VGA/SVGA displays can produce, their color depth is limited to 8 bits per primary color. This means that they are capable of displaying a maximum of 256 shades of each primary color (red, green, and blue), resulting in a total of over 16 million possible colors.
Why Was Super VGA Important?
The introduction of Super VGA was significant because it allowed for higher resolution displays and therefore, more detail and clarity in images and text. This was particularly useful for professionals in fields such as graphic design and engineering who required higher quality displays for their work.
Additionally, Super VGA paved the way for even higher resolutions and more advanced display technologies, such as modern day 4K and 8K displays.
In The decision, the introduction of Super VGA was a major milestone in the evolution of screen resolution. Its higher resolution capabilities paved the way for more advanced displays that we use today. While VGA and SVGA are now considered outdated technologies, they played an instrumental role in the early development of displays and continue to be studied by technology enthusiasts and historians.
