Further information
Display modes
The display mode and monitor uses are controlled by the computer. Therefore, refer to your
computer documentation for details on how to change display modes.
The image size, position and shape may change when the display mode changes. This is
normal and the image can be readjusted using the monitor controls.
To ensure flicker-free operation, select the highest (non-interlaced) refresh rate both the
computer and the monitor can support, (generally 75 Hz or higher), for the addressability that
your application requires.
For the display modes listed below, the screen image has been optimised during manufacture.

Power Management
To benefit from power management, the monitor must be used in conjunction with a computer
that implements the Video Electronics Standards Association (VESA) Display Power
Management Signalling (DPMS) Standard.
The power management feature is invoked when the computer recognizes that you have not
used your mouse or keyboard for a user-definable period of time. There are several states as
described in the table below.
