12-Bit Simultaneous Grayscale Display
Many current monitors use anti-glare panels, which have a waffled
surface to diffuse the reflection of surrounding light. However, this
also diffuses the light from the monitor’s backlight, which affects the
outline of an image, causing a viewing strain on the observer. With a
distinctive glare panel, there is no diffused reflection by the waffled
surface, and the outline of the image is displayed more clearly.
Therefore, the subtle images such as calcification and masses will be
easier to observe reducing the strain on the observer.
Sharper Resolution for Clearer Image Outline
MTF (Modulation Transfer Function) is a parameter to
define the display sharpness and resolution of a monitor
panel. The glare panel has better MTF characteristics than
the anti-glare panel meaning the
glare panel can be expected to
display the outline of a detailed
image more sharply.

Brightness Stabilization
At startup or upon wakeup, the EIZO patented drift correction
function quickly stabilizes the brightness level. In addition, a sensor
measures the backlight brightness and compensates for brightness
fluctuations caused by the ambient temperature and the passage of time.
Compatibility with Various Graphics Boards
Supports various input signals for compatibility with a wide
range of graphics boards so the user can select the board
according to budget and performance requirements. This
includes single link and dual link signals, as well as packed-
pixel signal for users requiring 12-bit or 10-bit simultaneous
display.
Backlight Saver
With ScreenManager Pro for Medical utility software
installed, the Backlight Saver function allows for the monitor’s
backlight to turn off when the screen saver is activated and
the monitor’s backlight to turn on when the computer comes
out of the screen saver mode. This function helps to reduce
power consumption when the monitor is used for a prolonged
period of time.
High-Resolution for Delicate Grayscale Shadings
When selecting a monitor, it’s important to consider the “information
volume” of the medical images to be displayed.

Please note that the reflection of surrounding light may increase when used in a bright environment.
Available with either a glare panel (GS520-CLG, GS520-BLG) or anti-glare panel (GS520-CL, GS520-BL).
This brightness stabilization function is EIZO patented technology (Japan patent numbers 3171808 and
3193315, US patent number 6188380).
0.165mm pixel size is the smallest pixel size among current
EIZO medical monitors providing high-definition and high-
density
display without shadings
appearing granular.

To sustain image consistency, brightness uniformity is
required for medical imaging monitors. However, unified
luminance of the backlight is difficult to attain due to the
characteristics of LCD monitors. The Digital Uniformity Equalizer
(DUE) function provides optimum backlight luminance uniformity.

“Information volume” of a digital mammography image
should exceed 5 million pixels. When a lower resolution
monitor displays this “information volume,” the monitor
stretches the information forcing the mosaic to appear as shadings.
With a 2048 x 2560 resolution or 5.24 million pixels, the stretching
effect is minimized and the mosaic becomes suitable for rendering
subtle masses and calcifications, within the mammography image.
