Glossary
Polarizer
A light filter which only allows light waves of a certain rotation through. Polarized material with perpendicular filtering is
used in LCDs to enclose the liquid crystal. The liquid crystal is then used as the medium which twists the light waves 90°
in order to allow the light to pass through or not.
Refresh rate
The number of times per second the screen is refreshed or redrawn. This number is usually stated in Hz (Hertz) or cycles
per second. A rate of 60 Hz is equal to 60 tomes per second.
SmartContrast
Unique technology that dynamically analyzes displayed content and automatically optimizes a LCD monitor's contrast
ratio for maximum visual clarity and viewing enjoyment, stepping up backlighting for clearer, crisper and brighter images
or dimming backlighting for clear display of images on dark backgrounds. For monitors with SmartContrast, contrast ratio
achieves 3000:1, the highest available today in a desktop LCD monitor.

tuning resolution, color calibration and other display settings including brightness, contrast, clock & phase, position, RGB,
white point and - on models with onboard speakers - volume adjustments.
