Color Adjustment
Color adjustments give the user the flexibility to customize color settings for different types of
applications. Text based applications that use light backgrounds with black text benefit from cooler
bluish white “paper like” colors. Color / graphics applications like web page development and pre press
benefit from warmer reddish color adjustments. Optimizing the monitors color settings will provide for
more accurate color reproduction and accuracy.
Cornerstone monitors are optimized at the factory for text based applications. The default color setting
of 9000°K provides paper white performance that is critical for today’s business applications.
When you set up a Cornerstone monitor, you can adjust the “white point,” or the color temperature using
the direct digital user controls, If your application is color intensive, you would choose a white point of
6500°K. For printed reproduction, a white point of 5000°K will match standard viewing conditions.
