Purpose
Many monitor applications require that the displayed image or text fit completely within a bezel that surrounds the
CRT. This usually requires that you first center the blank raster on the face of the CRT, and then center the image
within the raster. Use this image for centering the raster on the CRT.

Method
Turn up your monitor's brightness control until the raster is just visible. Adjust the raster's position and size using
the size and raster centering controls. The raster centering adjustment for many monochrome monitors consists of
moving magnetic rings on the deflection yoke.
