Property Description
MaxBrightness
This property defines the maximum value of brightness of the
video output device. Different manufacturers may have
different values.
MaxContrast
This property represents the maximum value of contrast of
the video output device. Different manufacturers may have
different values.
MaxQuiesceTime
The use of this property has been deprecated. When
evaluating the use of Quiesce, it was determined that this
single property is not adequate for describing when a device
will automatically exit a quiescent state. In fact, the most
likely scenario for a device to exit a quiescent state was
determined to be based on the number of outstanding
requests queued rather than on a maximum time. This
decision will be re-evaluated and repositioned later.
Deprecated description: Maximum time, in milliseconds, that
a Device can run in a "Quiesced" state. The state is defined
in its Availability and AdditionalAvailability properties, where
"Quiesced" is conveyed by the value 21. What occurs at the
end of the time limit is device-specific. The Device can
unquiesce, can be offline, or can take other actions. A value
of 0 indicates that a Device can remain quiesced indefinitely.
MCCSVersionNumber
This property represents the version number of the Monitor
Command and Control Set (MCCS) standard recognized by
the display.
OperationalStatus
Indicates the current statuses of the element. Various
operational statuses are defined. Many of the enumeration's
values are self-explanatory.
Possible values are:
• 0 = Unknown
• 1 = Other
• 2 = OK
• 3 = Degraded
• 4 = Stressed - Iindicates that the element is
functioning, but needs attention. Examples of
"Stressed" states are overload, overheated, and so
on.
• 5 = Predictive Failure - Indicates that an element is
functioning nominally but predicting a failure in the
near future.
• 6 = Error
• 7 = Non-Recoverable Error
• 8 = Starting
• 9 = Stopping
• 10 = Stopped - Implies a clean and orderly stop
• 11 = In Service - Describes an element being
configured, maintained, cleaned, or otherwise
administered.
• 12 = No Contact - Indicates that the monitoring
system has knowledge of this element, but has never
been able to establish communications with it.
• 13 = Lost Communication - Indicates that the
ManagedSystem Element is known to exist and has
