Contrast is the ratio of white to black and for monitors is normally stated as a dark room contrast from a controlled laboratory environment. Typical contrasts on printed paper are 6:1 for newspapers, 31:1 for laser printers, 49:1 for photo paper. For example, dark room contrasts cannot be achieved in the office because an extremely deep black cannot be achieved in normal ambient light – even with the screen turned off.
The ColorNavigator software is used to simply and accurately calibrate ColorEdge screens.
To optimize calibration, make sure that the ambient light that appears on the monitor image and the sensor during calibration corresponds to the usual working conditions at the computer workstation.
Smart Resolution is a technology patented by EIZO, which checks the screen content for noise and blurring. Smart Resolution ensures that noise is not amplified and sharpens the image by correcting blurring. For a game, for example, Smart Resolution can resharpen the image to make it seem more life-like. For other content, such as photos and websites, Smart Resolution differentiates between skin tones and improves how they look.
Devices with an integrated calibration sensor are able to perform calibration without the help of the user. The computer does not even need to be switched on. When programmed once, the calibration will start at night, during the lunch break, or at other, definable times. It is easy to program using the ColorNavigator or the on-screen menu.
The viewing angle relates to the angle, beneath which the contrast is better than 10:1. These are normally values of 160° to 178°. These values do not provide any information about what enormous differences in contrast may result within the viewing angle. The contrasts should not change significantly for users with a perpendicular view and a slightly side-on view. It must not make a difference whether the viewer is looking at the middle of the image or the edge of the image. How much the contrast stability varies with different LCD technologies is best checked using a measurement diagram or by a direct visual comparison. The more stable the contrast in the user's viewing frustum, the better the image rendering.
The letters behind the numbers have the following meanings:
BK: Black casing
GY: Gray casing
WS: White/silver casing
The color temperature is a benchmark for measuring the white tone and is stated in Kelvin. At high temperatures, the white tone appears slightly blue, while it has a more red tone at low temperatures.
5000 K: Often used in the printing industry.
6500 K: Suitable for displaying photos and video images.
EIZO monitors are normally equipped with two or more signal inputs. You can seamlessly switch back and forth between two or more PCs by pressing a button, signal 1-2 or "S", depending on the model.
