Whats the difference between a shadow mask vs. aperture grille?
The CRT (Cathode Ray Tube) mask is a major component of the picture tube. There are two major types of CRT masks: the shadow mask and the aperture grille, also called stripe mask. Both types of monitors produce excellent image quality. An aperture grille displays brighter images with richer and more saturated colors.

For color graphics applications such as electronic desktop publishing, the aperture grille technology is often preferred for its
