An integrated calibration sensor governs the maximum color accuracy. It positions itself automatically for calibration and then conceals itself in the safety of the casing until the next measurement is taken. Each monitor is exactly coordinated using its sensor. For example, the measurement location is correlated with the middle of the image at the upper edge of the image so that the sensor takes measurements as if it were in the middle of the image. This integrated solution rules out the variability, which may arise when using external measuring devices. Even the influences of ambient light are determined when initiating the sensor and considered during calibration.
If the video signal has a limited color depth in the range of 16-235 instead of 0-255, black areas of the screen may appear gray. If colors are not displayed correctly, this may be down to the so-called YUV format. This problem can be resolved by adjusting the color space.
International standard for an RGB color space. A color space has been defined, which most devices can comply with, to enable color matching between various applications and devices, such as monitors, scanners, and digital cameras. sRGB images, which are detected or issued on "sRBG devices" are limited to the full sRBG color range and no colors outside the sRBG color space. Color allocation, white point, and gamma are permanently defined.
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.
This is where the signal values are allocated to the color tone values for the output in the monitor. EIZO monitors are 16, 14, 12, or 10 bit instead of the conventional 8 bit look-up table (LUT) for precise color control. Precision work, performed by a high-performance chip developed in-house at EIZO.
The ColorNavigator software is used to simply and accurately calibrate ColorEdge screens.
The letters behind the numbers have the following meanings:
BK: Black casing
GY: Gray casing
WS: White/silver casing
X or A: Successor product with the same model name
H: Pillar base
FS: FlexStand base
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.
EIZO has developed the RadiCS software specifically for quality assurance for image display devices in the RadiForce range. It offers extensive tests and automatic alignment to guarantee constant and consistent image reproduction on all RadiForce LCD monitors, but also supports screens from other manufacturers. The software automatically executes test images and helps to perform measurements and assessments in accordance with the guidelines in a cost-effective and time-effective manner. For example, measurement results are automatically transferred to the documentation and archived and can be centrally managed using the optional RadiNET Pro software. A calendar with a reminder function ensures timely checks are performed. A suitable measurement device is required to measure the luminance, including veiling luminance. Measured values from various luminance meters are automatically read by RadiCS.
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.
