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.
R
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.
S
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.
