Environmental Influence

All ColorEdge models come with an ASIC (application specic integrated circuit) developed by EIZO to meet the needs of the

graphics market. The ASIC has its own algorithms used in high-precision color processing to produce smooth color tones.

EIZO-Developed ASIC at the Core

From the time it is turned on it typically takes 30 minutes or

longer for a monitor’s brightness, chromaticity, and tone

characteristics to stabilize. EIZO has shortened this warm-up

time by more than 75% to a mere 7 minutes. For conrming

your work in a photo studio or taking your monitor with you

on location, you can get to work right away.

Color That’s Ready When You Are

The gamma level for each ColorEdge monitor is adjusted at

the factory. This is accomplished by measuring the R, G, and

B gamma values from 0 – 255, then using the monitor’s

16-bit look-up table (LUT) to select the 256 most appropriate

tones to achieve the desired value.

Individually Adjusted at the Factory

The 178° viewing angles afforded by the IPS panel technol-

ogy allows two or more people to view the screen at once

with little change in color or contrast.

Wide Viewing Angles with IPS Panels

Using the DisplayPort input, the monitors offer 10-bit simulta-

neous color display* from a 16-bit look-up table which means

they can show more than one billion colors simultaneously.

This is 64 times more colors than you get with 8-bit display

which results in even smoother color gradations and reduced

Delta-E between two adjacent colors.

*A graphics board and software which support 10-bit output are also

necessary for 10-bit display. 10-bit display is only available through the

DisplayPort input.

10-Bit Simultaneous Display

An EIZO-patented sensor detects changes in the backlight

that cause the monitor's brightness to decline over time and

compensate for them. This not only stabilizes the brightness,

but also minimizes changes in the color temperature that

occur when brightness changes. Another sensor is included

that detects changes in the ambient temperature and

prevents uctuations to the chromaticity and gamma.

Stable Brightness

A wide color gamut reproduces almost the entire Adobe RGB

color space* so images shot in RAW can be converted to

Adobe RGB or images shot in Adobe RGB will be displayed

correctly. The colors seen in photos of vibrant blue skies and

lush green forests will be reproduced faithfully in a way that

cannot be on monitors with an sRGB color space. The wide

color gamut also ensures that the monitors reproduce almost

the entire ISO-coated and US web-coated CMYK color

Wide Color Gamut

Fluctuations in brightness and chromaticity on different

parts of the screen are a common trait of LCD monitors.

EIZO's patented digital uniformity equalizer (DUE) technol-

ogy compensates for these uctuations to produce a more

uniform image across the screen. And now DUE also

counterbalances the inuences that a uctuating ambient

temperature may have on color temperature and brightness

to ensure stable image display.
