L1951p Wide Flat Panel Monitor User's Guide

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

mode.

The display modes shown below have been optimized at the factory.

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.
