on the icon. This screen (figure 37 on page 85) shows
properties of the currently active display.
Name: Displays the model name of the display.
Serial Number: Displays the serial number of the
display.
Backlight RunTime: This is time in hours that the back
light has been on. A common question is: How much
longer will the backlight last? The backlight will typically
last a very long time, but will only be able to hold a
calibrated output of 500 cd/m² for 17000 hours, after
which time it will become slowly dimmer. For displays
calibrated at 500 cd/m², an estimate of how long it will
be before a backlight replacement is needed = 17000
hours – backlight age.
Firmware Revisions: This is the runtime firmware that
is loaded in the display. This information may be helpful
when there is a problem.
Internal Temperature: This is the temperature inside
the display. It starts out at about the ambient
temperature when the display backlight is first turned
on, then rises slowly to a steady-state temperature as
the display warms up. Changes in light level due to
temperature variations are completely controlled by the
I-Guard sensor on the front of the display.
Current Luminance Value: This is the current
luminance value of the display. It may vary a bit from
time to time, for the display continuously calibrates itself
to meet the target luminance value.
