4.7 Smart Power
Public Signage has introduced “SmartPower” and “panel saving/brightness” as green features in
their new product line. These controls influence the power consumption by changing the level of
the backlight of the screen. To even make a more green impression also the initial settings of
the monitor are such that they tent to consume less power than the competitors do. For this the
light output of the backlight of the LCD screen is set to a as low as possible level, but such that
the picture performance is still acceptable.
Settings should behave as following:

b) MEDIUM: 80% of power consumption relative to current settings (range±10%)
c) HIGH: 65% of power consumption relative to current settings (range±10%)
3) Panel saving/Brightness ON: 40% of maximum power consumption (range±10%)
The controls settings should only be visible on its own controls. It should not have secondary
effects on other controls (ea brightness setting changes when smart power setting has changed).
