Autoscan
A microprocessor-based feature of Philips Brilliance monitors is able to detect automatically
horizontal and vertical frequencies of input signals with those of the installed video card. An
autoscan monitor can thus operate with a wide range of video cards. MultiSync, a registered
trademark of NEC, provides a similar function.

Color temperature

A way of describing the color of a radiating source in terms of the temperature (in degrees Kelvin)
of a black body radiating with the same dominant frequency as the source.
Most Philips monitors offer the possibility of setting the color temperature to any desired value.
Contrast
The ratio between the brightness of the brightest and darkest parts of a picture. The darkest part
of a picture is set by the brightness of the unexcited phosphor, which is governed by the degree

light levels. Black Matrix tubes reflect less ambient light so exhibit higher contrast than other
tubes.
Convergence error
Bean misalignment causing one or more of the three beams passing through the wrong aperture
in the shadow mask and striking a phosphor dot in the wrong triad.
Convergence error is expressed in mm often at two well-defined points on the screen, designated
