Selecting a supported display mode
The display mode the monitor uses is controlled by the computer. Therefore, refer to 
your computer documentation for details on how to change display modes.
The image size, position and shape might change when the display mode changes. 
This is normal and the image can be readjusted using automatic image setup and the 
image controls.
Unlike CRT monitors, which require a high refresh rate to minimize flicker, LCD or 
Flat Panel technology is inherently flicker-free. 
Note:  If your system has previously been used with a CRT monitor and is currently 
configured to a display mode outside the range of this monitor, you may need to re-
attach the CRT monitor temporarily until you have re-configured the system; 
preferably to 1366 x 768 at 60 Hz, which is the Native Resolution Display mode. 
The display modes shown below have been optimized at the factory.

Understanding power management
Power management is invoked when the computer recognizes that you have not used 
your mouse or keyboard for a user-definable period. There are several states as 
described in the table below. 
For optimal performance, switch off your monitor at the end of each working day, or 
whenever you expect to leave it unused for long periods during the day.
