Super video graphics array Super VGA or SVGA is a high-resolution standard used to channel video data to a compatible visual output device - usually a computer monitor. This is actually a broad umbrella term for other computer display standards. Initially, SVGA was defined as having a resolution of x 4-bit pixels capable of a variety of 16 colors with each pixel.
Later, it was lengthened to x 8-bit pixels having an array of different colors. With the continuing innovation of technology, the number of colors has become unimportant, as the shades of each color are set by a changeable analog voltage, which theoretically means that the SVGA can display an infinite number of colors.
Despite this possibility, digital video cards can only live up to the specifications of the era in which they were manufactured, limiting the amount of displayed screen colors.
Another factor that can affect the number of colors is the video interface that connects the adapter and monitor, which changes the signal from digital to analog to give the monitor more color variety.
VGA as it provides smaller resolution videos and images has a memory of up to k. Where supplementary memory is not included. SVGA as it provides bigger resolution videos and images has a memory of up to k. Where supplementary memory is included. It takes the screen color of colors from , colors collection that uses 6-bit digital to analog converter for converting analog red, green, and blue signals which carry separate information for each red, blue and green color.
It takes the screen color of either colors or 16 million colors which is depending on the video or image memory that is installed in the computer.
Sometimes basic VGA cables consist of 15 wires which can support the lower resolution or even lesser than the provided in VGA, where cables have foil shield. VGA cables are less expensive as the VGA cables are foil shields and hence they are not better for performing signal intact where in this it may start to deteriorate. An SVGA cable is more expensive than VGA cables as cables are thicker than VGA with better shielding and also is provided with gold plated to increase the conduction between male and female ports hence the cables are costlier than VGA cables for achieving better signal intact.
These are not recommended for long-distance VGA cables as the devices connected through these VGA cables which are far having distance of more than 10 feet can degrade in terms of signal transmission.
SVGA is best suited for long distances though it is expensive. If we want to go economically then we can also use VGA cables with a repeater, or signal enhancers, which help to reach longer distances according to the needs. This VGA cable has 14 pin configurations with 1 st and 3 rd row with 5 pins and 2 nd row with 4 pins. But these cables have 3 rows with 15 holes.
