SVGA
No doubt that the world of digital screen resolutions is upon us, but analog screen resolutions are still the most popular and widely used thanks to our CRT TVs. To date, one of the most common standards for analog screen resolution has been the SVGA. SVGA or Super Video Graphics Array has been defined as having 800 horizontal rows by 600 vertical rows usually written as 800 X 600, which is more than the erstwhile used VGA, which had a resolution of 640 X 480.While Super VGA was first defined as a resolution of 800 X 600 4 bit pixels in 1989, it soon increased to 1024 X 768 8 bit pixels and later on extended to 1280x1024 with 16 million colors.
High resolution SVGA devices ensure that the quality of the image is better. High resolution SVGA projectors or SVGA monitors are equipped to show more picture details than low resolution display devices, since there are more pixels used to make the image and each individual pixel is smaller. While academically, a resolution of ‘800 x 600' is SVGA, ‘1024 x 768’ is XGA and ‘1280 x 1024' is defined as SXGA, they are still most commonly known as SVGA only. No wonder then that SVGA is still the most commonly used resolution among computer monitors and also for television screens.
Thus, most of our display devices are high resolution SVGA and the world is populated with SVGA monitors, SVGA projectors, SVGA Variable Gain Amplifiers and SVGA TV screens. SVGA scan converters are commonly used in order to get the computer’s SVGA resolution output and convert it for a high resolution NTSC-PAL viewing on old CRT TVs. Companies like Sony have put wireless Super VGA TVs in the market. And most DVD players and Webcams have an SVGA out port so that they can be easily connected to display devices using SVGA cables. The market is full of SVGA splitters that let you view output from a single source on two or more SVGA monitors. So you can watch a movie played on your digital resolution DVD player, which is converted through a DVI SVGA adapter and routed through SVGA video splitters and SVGA cables on two or more displays.
