· monitor product ID
· time that the monitor has spent in power-on and standby modes (in hours)
· polarity of the videosync signal
· video frequency
· current power status
· current video timing
· current color mode
· whether power-save has been activated
· OSM lock status
· diagnostic data
· power-off timer settings
Many practical uses result from this. Monitors within the organization that are physically suitable for a
specific, possibly temporary, use can be quickly located. With reference to the manufacturing data, the
probability of failure can be investigated at any time or the costs for the next new procurement can be
evaluated and planned for at an early stage. The administrator can very quickly determine the effectiveness of
the power-save mode at workstations by collecting and analyzing the status times of all monitors.
Furthermore, the power-off settings can be optimally matched to the actual operating times in the company.
Another important feature is the ability to determine diagnostic data from a monitor in order to quickly
rectify failures or to prevent them.
Remote-controlled monitors
An integral function of NaViSet is the remote control of the monitor settings and the manipulation of the
electrically erasable programmable read-only memory (EEPROM). The following functions can be controlled
remotely (provided they are supported by the monitor):
· demagnetization of the screen using the degauss function
· resetting of all functions to the factory settings (factory reset)
· resetting the colors to standard values
· resetting all geometrical corrections
· auto setup
· OSM lock/unlock
· power-save status
· power on/off/standby
· power-off time setting (timer)
· color-preset settings
· adjustment of the individual control functions
These functions offer many maintenance and asset-management beenfits. For example, the degauss function
enables all CRT monitors to be demagnetized at regular intervals, quite independently of the user's normal
practice. As a result, predominantly in sensitive graphical environments, possible errors due to incorrect colors
and geometrical distortions can be minimized. The same applies for a reset to a preset standard color value,
which is particularly important in color-sensitive, color-calibrated environments. The system administrator
can thus very quickly correct unintentional setup errors made by unauthorized persons, without having to
walk from one workstation to the next each time. Incorrect adjustments to the geometrical functions can also
be quickly rectified in this manner (geometrical reset).
The remote control of functions that help to reduce power
consumption or increase the life of the monitor is beneficial
when the changeover to summer time occurs, when the
working hours at certain workstations change or when
incorrect settings have to be rectified and then prevented by
remotely disabling the OSM. When monitors are remotely
switched off by the administrator, the security factor is
enhanced in particularly sensitive environments, as a monitor
that is switched-off and locked-out is rendered inoperable to anyone illegally trying to access data (for
instance at night).
