Contrast is therefore reduced in conditions of high ambient light levels. Black Matrix tubesreflect less ambient light so exhibit higher contrast than other tubes.Convergence errorBean misalignment causing one or more of the three beams passing through the wrong aperture in theshadow mask and striking a phosphor dot in the wrong triad.Convergence error is expressed in mm often at three well-defined points on the screen, designated A, Band C (see figure ).
