GLOSSARY
A
Autosizing-True autosizing occurs when a monitor can maintain a constant image size across different video modes. Two common ways of achieving autosizing are mode sensing, pre-programmed factory settings and user defined modes.
B
Bandwidth-The range of frequencies over which the video display’s electronics can respond. This is directly related to the speed at which the monitor can accept pixel information and to the maximum resolution the monitor can display.
Barrel-A type of distortion in which an images’s sides or top (or both) appear to bulge outward.
Blooming-When image brightness increases, the CRT’s electron beam tends to spread out and lose focus. This loss of focus on bright portions of an image makes the image appear to expand or “bloom”, and lose detail.
Bow-A type of distortion in which opposite sides of the screen image curve in the same direction.
C
Convergence-The ability of the monitor to correctly align the red, green and blue components of an image on the screen. Convergence problems are often visible as fringes of color at the edge of the screen or color around text or graphics where it should be white.
CRT-An acronym for cathode ray tube. A type of display in which images are created by electron beams that caused the glowing of phosphors inside the surface of a glass screen.
D
DAF-Dynamic Astigmatism Focus. A technique using a quadruple lens to focus the electron beams horizontally and diffuse it vertically.
Dot Pitch-The distance between a phosphor dot and the next nearest dot of the same color on a CRT, expressed in millimeters. The dot pitch does not correspond to the display resolution in pixels. Instead, the CRT’s electron beam hits one or more phosphor dots to create a pixel. Monitors with smaller dot pitches generally produce sharper images because smaller phosphor dots can be used to represent each pixel more accurately.
