How can convert high VGA resolution into low VGA resolution Can use any electronic converter or device please tell?

Answer 1

Devices called scalars or interpolators are made to convert images in this way. They can convert from PC signals to broadcast standard, PC to PC, broadcast to PC or even between broadcast standards. They all work by looking at the incoming image and then estimating the value of every pixel on the redrawn image. Because they change the muber of pixels across the screen in both planes, new pixels are drawn in places where there wasn't a pixel in the incoming image. Because of this method, they will all make the image a little softer than the original. In some cases, they can cause quite unpleasant effects around text and hard lines on the image. Although it is possible to obtain low cost scalars, they may not provide the quality needed. (some of the more expensive broadcast converters have price tags of $200,000 to get the best quality possible). Alternatively, it may be possible to set up the output of the PC to the resolution required. This will always give a better image quality than converting because the graphics are generated to suit the resolution of the display.
