Premium Edition Model
As a ColorEdge Premium Edition model, the CG223W 22" offers the following benefits.
Connect with up to three PCs via the monitor's dual DVI-I inputs which accept digital and analog signals, and the DisplayPort (digital) input terminals. DisplayPort is next-generation connectivity that transmits both video and audio signals.
10-Bit Simultaneous Display
This monitor employs a 12-bit look-up table with a color palette of 68 billion colors from which the most appropriate 16.7 million (8 bits) are displayed. It also uses 16-bit internal processing for smooth display of grayscale tones without banding. What’s more, using the DisplayPort input, this monitor displays 10-bit color* which is more than 1 billion colors shown simultaneously. This is 64 times greater than the 16.7 million colors of 8-bit display. The result is even smoother color gradations and noticeably reduced Delta-E between two adjacent colors.
*A graphics board and software which support 10-bit output are necessary for 10-bit display.
16-Bit Internal Processing
With most LCD monitors, the black level is usually too bright which leads to banding and washing out of dark grays. 16-bit internal processing allows the monitor to reproduce a high level of detail in dark areas.
Brightness and Color Uniformity with DUE
Fluctuations in brightness and chroma on different parts of the screen is a common trait of LCD monitors. To counteract EIZO a digital uniformity equalizer (DUE). DUE utilizes the monitor's 12-bit look-up table (LUT) with an extensive palette of 4,081 grayscale tones for each R, G, and B, and internal calculation accuracy of 16-bits. This ensures a Delta-E difference of 3 or less across the screen when the monitor leaves the factory.
Factory Adjustment of Gamma
To ensure that each ColorEdge monitor produces the most accurate and consistent color gradations possible, EIZO carefully measures and sets every shade of R, G, and B from 0 − 255 on the production line with the monitor's 12-bit Look-Up Table, to produce a monitor gamma value of 2.2. Should the user prefer a different value, ColorNavigator software can be used to set the gamma value from a range of 1.0 up to 2.6 in increments of 0.1.
Verification Documents Included
EIZO stands behind the quality of the ColorEdge series by including two verification documents with each monitor. One document verifies the uniformity on 25 points across the screen while the other certifies that all 256 color tones on the gamma curve were individually adjusted at the factory.
Brightness and Color Temperature Stability
To ensure proper display of color, the ColorEdge CG223W comes equipped with patented EIZO technology that stabilizes the monitor’s brightness level after startup or coming out of power saving mode. Furthermore, a temperature sensor detects and automatically suppresses changes in color and brightness caused by fluctuations in the surrounding temperature.
3D LUT for Better Additive Color Mixture
The monitor utilizes a new EIZO-developed 3D LUT. Whereas a typical 1D LUT adjusts color on separate tables for each red, green, and blue, a 3D LUT accomplishes this on a single, mixed-color cubic table. A 3D LUT improves the monitor's additive color mixture (combination of RGB), a key factor in its ability to display neutral gray tones.
Customer Assurance
A five-year warranty offers a long service life, and compliance with leading industry standards such as TCO'03 and TUV Ergonomics ensures a better working environment. The EIZO Eco Products 2006 label indicates these products meet strict internal requirements for design, manufacturing, packaging, and usage, including the introduction of lead-free solder and chrome-free steel plates.
