Factory calibration and 
consistency.
 
Using state-
of-the-art equipment 
during production, each 
NEC MultiSync MD Series 
monitor is calibrated to the 
DICOM display function 
for luminance and to a 
desired whitepoint (color 
of the white). NEC Display 
Solutions’ patent-pending 
X-Light
TM
 technology (Fig. 
1) has the unique ability 
to control and adjust the 
luminance and whitepoint 
via an integrated fast-feed-
back internal backlight 
sensor, which continuously 
monitors and realigns 
these settings to maintain 
the factory calibration 
throughout the life of the 
monitor. X-Light technol-
ogy also alleviates the 
color shift of the backlight 
to the yellow spectrum.
Monitor matching and re-
duced downtime. X-Light 
helps reduce service costs 
as it enables a more flexible use of display equipment. Since all 
X-Light-equipped monitors are set for the same whitepoint dur-
ing production, they can be exchanged at any time within one 
location and swapped in existing dual- or multi-screen configu-
rations without calibration.
Standalone calibration and monitor matching.
 NEC MultiSync 
MD Series monitors have been designed to maintain their fac-
tory calibration. However, if calibration or matching (Fig. 2) to 
a replacement is required, the monitors can be configured using 
the built-in, standalone algorithm programmed into the monitor’s 
firmware. This feature is useful for monitors that are not used in 
a setup where calibration can easily be performed with a PC and 
external software or non-supported 
operating systems.
GammaComp™ MD calibration and 
conformance software.
 Quality control 
and calibration/matching can also 
be accomplished using GammaComp 
MD (shipped with display), ensuring 
consistent image quality on a single 
display system. The software main-
tains the monitor’s conformance to the 
DICOM standard, while providing an 
easy-to-use QA environment for medi-
cal imaging. Optionally, GammaComp 
MD Administrator provides centralized 
control and management of multiple 
display systems. 
Modern medical technology enables complex examinations. But in 
the end, it is the radiologist who is responsible for fast and accurate 
diagnostic findings. To support these findings in a soft copy read-
ing environment, flat-panel displays need to comply with the highest 
visual requirements. Their image quality has a decisive influence on 
diagnostic accuracy.
MultiSync MD Series grayscale displays – in combination with the 
appropriate graphics controller – are designed for diagnostic imaging 
and for use in Picture Archiving and Communication System (PACS) 
applications. Furthermore, diagnostic imaging displays from NEC 
Display Solutions are based on technologies and functions which 
actively contribute to a reduction of cost of ownership.
