Color monitor 19T2
If your PC detects inactivity (no input) it sends an appropriate signal to the monitor to reduce the
power consumption. The power indicator of the monitor changes color to indicate the status change.
If there is still no input, power consumption is further reduced (OFF mode).
Once an input is made at the PC the screen contents are redrawn and full power is restored.
The length of the individual stages is determined by the power management system of the PC. For
detailed information on how energy-saving mode operates refer to the Operating Manual or
Technical Manual of your PC.
The service life of your monitor will be extended if the OFF mode is switched to after
i
30 minutes at the earliest (setting in screen saver, in your PC's BIOS setup or in the OSD
menu).
When the monitor is switched to OFF mode by the power management system a power
consumption of about 3 W is maintained to feed the circuit for redrawing the screen
contents.
To cut off power consumption totally, press the ON/OFF switch on the front of the monitor.
Changing the monitor settings
With the buttons on the control panel, you can change the monitor settings. Most settings are
carried out via an integrated OSD menu (On-Screen Display).
The OSD menu is available in different languages. The English menu names are used in
i
the following description (default setting). How you set a different language for the OSD
menu is described in the section "Setting the language for the OSD menu (LANGUAGE)".
