Display modes
The display modes 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 that 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 optimized during manufacture.

640 x 480 60Hz 31.5kHz
720 x 400 70Hz 31.5kHz

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
described in the table below.
