    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 ch\
    anges.
    This is normal and the image can be readjusted using automatic image set\
    up 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 1920 x 1200 at 60 Hz, which is the Native Resoluti\
    on
    Display mode.

    Image rotation
    Before rotating the monitor, you should set-up your computer to rotate the image.
    Rotating the image may require special rotation software or you may find\
     that your
    computer is preloaded with video graphic drivers that allows image rotat\
    ion. Check
    the Graphic Properties setting on your computer to see if this feature i\
    s available.
    Try these steps to check if image rotation is available on your computer. 1. Right-click on the desktop and click  Properties.
    2. Select the  Settings tab and click  Advanced.
    3. If you have ATI, select the  Rotation tab and set the preferred rotation. If you have
    nVidia, click the  nVidia tab, in the left-hand column select  NVRotate, and then
    select the preferred rotation. If you have  Intel, select the Intel graphics tab, click
    Graphic Properties , select the Rotation tab, and then set the preferred rotation.
    Check with the manufacturer of your computer to see if graphic drivers w\
    ith image
    rotation can be downloaded from their support website.
    Understanding power management
    Power management is invoked when the computer recognizes that you have n\
    ot used
    your mouse or keyboard for a user-definable period. There are several states as
    described in the table below.
