Selecting a supported display mode
The display mode of the monitor uses is controlled by the computer� Therefore, refer to your
computer documentation on how to change display modes�
The image size, position and shape might be changed when the display mode changes� This is
normal and the image can be re-adjusted 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 reattach the CRT monitor
temporarily until you have re-configured the system; preferably to 1920 x 1080 at 60 Hz, which is
a common 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�
Table 2-3.
