configuration and troubleshooting, thus further decreasing the
support costs, time and TCO.
The Console application performs three main types of operations:
1. Connecting one-to-one with a remote machine – In this case,
it is possible to remotely query and control a single machine at a
time. Controls on the remote display monitors can be adjusted in
real time. This is most effective for remote service, support and
individual configuration. More than 50 different controls can be
read and adjusted remotely, depending on the monitor model.
2. Performing configuration commands on many remote ma-
chines – A list of configuration operations to be performed on dis-
play monitors connected to multiple remote machines is selected.
For example, "adjustment reset" commands could be issued to all
the displays on all machines in a classroom. The results of each
command, as performed on each remote machine, are logged
and can be viewed as an Excel spreadsheet. Commands can be
scheduled to be performed at specific times if needed.
3. Querying the configuration and metadata on many remote
machines – In this case, a list of remote machines to query is
specified as well as a list of which configuration and metadata
items are to be retrieved and reported. The results of each query
are logged and can be viewed as an Excel spreadsheet. Queries
can be scheduled to be performed at specific times if needed.
NaViSet Administrator provides a wealth of information about
the current state of the display monitors connected to a remote
machine, and well as related configuration and metadata infor-
mation. Examples of this type of information are:
Display monitor related:
• Manufacturer
• Model
• Serial Number
• Date of Manufacture
• Type of display (LCD, CRT, etc.)
• Screen size (horizontal, vertical and diagonal in inches and
centimeters)
• Monitor driver version
• Number of hours used (hours "on" and hours with A/C applied)
• Electronic Asset Tag text
• Diagnostic information including internal temperatures
• Current settings of all controls
Graphics system related:
• Graphics card manufacturer, model and driver version.
• Current display resolution setting
• Current color depth setting
• Current video signal frequency
• Supported video signal frequency range
System related:
• Machine manufacturer, model and serial number
• Network name and connected domain name
• Screen saver timeout and password settings
SpectraView related:

• Last calibration date, time and status.
• Monitor usage since last calibration
• Target parameters and calibrated state measurements
Since all of the metadata, query and operation results can be
output in standard Excel spreadsheet format, data can easily be
further manipulated, compared, graphed, etc., allowing powerful
data mining operations to be performed without needing to invest
in expensive SQL servers and databases.
The Console will show any diagnostic messages reported by
remote displays, such as an internal fan failure or other condi-
tion. It can also flag certain inadvisable display configuration
settings that may lead to user discomfort or eye fatigue as well
as showing the underutilization of the monitor capabilities. For
example, it can display a warning message if any of the following
conditions are detected:
• An LCD monitor not being driven at its native resolution,
which may result in sub-optimal picture quality.
• An LCD monitor being driven with an analog video signal of
above 65Hz refresh rate, which may result in sub-optimal
picture quality.
• A CRT monitor being driven with an analog video signal of
below 70Hz refresh rate, which can lead to eye fatigue and
headaches.
• The video graphics adapter color depth setting set to less than
24 bit color, which leads to color posterizing and banding.
• The Windows Screen Saver power setting set to off, which
would prevent the display from entering a power saving mode.
NaViSet Administrator also integrates with other NEC technolo-
gies such as the SpectraView
II
current calibration parameters, calibration results and state of
remote display monitors can be accessed and tracked remotely.
This is particularly useful in applications in which a large number
of color-critical displays are deployed and maintained in a color-
calibrated state.
NEC display monitors also feature a unique electronic asset tag,
which allows a text string to be permanently electronically stored
in each display by the administrator. This text can be used for
internal tracking purposes, such as assigning a custom asset
number or code. This electronic version of a physical asset tag
has the advantage in that it can only be erased or altered by an
administrator and it can be read remotely.

In cases where a user has made some unwanted adjustments to
a display, the settings can easily be reset remotely to the default
conditions. In some applications such as a school or public envi-
ronment, it may be beneficial to prevent users from being able to
adjust the display monitors at all. The front control buttons and
