Product Information - Monitor Dot Pitch and Contrast Ratio Definitions

Dot Pitch

Dot pitch, or phosphor pitch, is a measurement that indicates the diagonal distance between like-colored phosphor dots on a display screen. Measured in millimeters, the dot pitch is one of the principal characteristics that determines the quality of display monitors. The lower the number, the crisper the image. The dot pitch of color monitors for personal computers ranges from about 0.15 mm to 0.30 mm.

Contrast Ratio

Contrast ratio is the ratio of luminance between the brightest white that can be produced by a display and the darkest black that can be produced by that same display. Contrast ratio is a major determinant of perceived picture quality: If a picture has high contrast ratio, you will judge it to be sharper than a picture with lower contrast ratio, even if the lower contrast picture has substantially more measurable resolution.
