IPS Panel with Wide Viewing Angles

The IPS (in-plane switching) panel offers 178° viewing
angles to minimize color shift and contrast when viewing the
screen at an angle. This ensures stable and consistent display
when two or more people view the screen at once or in a
multi-monitor environment.

A non-glare screen reduces eye fatigue by dissipating
reflective light that otherwise makes the screen difficult to
see.

Viewing Comfort with an Ergonomic Stand

Adjust the screen to the most comfortable position with 82
mm height adjustment, 40° tilt, 70° swivel, and 90° rotation
for portrait mode. Compatibility with VESA mounting
standards allows the monitor to be removed from the stand
for mounting on a movable arm or wall bracket.

10-Bit Gamma Correction

This technology helps achieve accurate color by converting
the 8-bit PC data to 10-bit, and assigning the ideal gamma
values with a 10-bit look-up table (LUT) then returning the
data to 8-bit format for display.

Optimized Brightness with Auto EcoView

The Auto EcoView ambient brightness sensor on the front of
the monitor measures ambient light and optimizes the screen's
brightness so the screen is never too bright or too dark. This
reduces both eye strain and the monitor’s energy consump­tion.

Auto EcoView Sensor

Preset Modes for Optimum Viewing

For optimum viewing of different kinds of content, EIZO's
Fine Contrast function includes modes for office applications
(Paper mode), video (Movie mode), web browsing (sRGB
mode), and user-defined settings (User modes 1 and 2).
Toggling between modes can be done manually in the OSD
menu or automatically by assigning a mode to a particular
application with the bundled ScreenManager Pro for LCD
software.

Closely Simulates Documents and Books

Paper mode produces tones and contrast similar to those of
printed paper. Together with the Auto EcoView ambient
brightness sensor, Paper mode makes reading documents and
ebooks more comfortable and reduces eyestrain. (See sidebar
for more information.)

What is Paper Mode?

Simply put, it is a mode which adjusts the brightness,
contrast ratio, and color temperature of a monitor to
simulate those of printed paper. Over the course of a work
day PC users must constantly adjust to the difference
between how monitors and paper appear. This overworks
the muscles of the eyes and is thought to be a source of
eye fatigue and stress. Paper mode was developed to
alleviate the eye fatigue and stress that PC users feel.

Color Temperature, Brightness and the
Effect on Blue Light

In the visible light spectrum, blue light has wavelengths
adjacent to ultraviolet light. Compared to the factory preset
setting of 6,500 K of typical LCD monitors, Paper Mode is
closer to the spectral distribution with long reddish
wavelengths so it reduces the amount of blue light, a cause
of eye fatigue.

Ultraviolet Light

The combination of Paper Mode and the Auto EcoView
brightness adjustment function reduces blue light even
more. In a monitor with an LED backlight where Paper
Mode and Auto EcoView were used, the blue light was
measured and found to have only 1/6
factory setting.
