The Auto Setup instructions require the monitor to be warmed up for 15 minutes. This is not required for normal operation.

By pressing the Auto key, you will have direct access to Auto Adjustment.

The AUTO SETUP process only applies to the current screen mode. When a new

mode is selected, repeat this section to reset the monitor.

Auto setup is not required when using digital input

When you first use your monitor you must perform Auto Setup. This procedure sets up your monitor to process the video signals from your computer without image discoloration or smearing. After you perform Auto Setup, the settings are stored and used each time you turn on the monitor.

To optimize the displayed image a set-up utility is provided on the CD. Operation of the utility is dependent on the operating system on your computer. For correct operation locate the operating system on your computer from the table below and follow the appropriate instructions. You can choose to run AUTO SETUP for each operating system that you use. This means that if you sometimes use your monitor while running a version of Windows and sometimes also use it from within DOS (not a DOS window), you must run AUTO SETUP for both Windows and DOS. You can run versions of AUTO SETUP in any order.

General Information

Display modes

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 AUTO SETUP and the monitor controls.

Unlike CRT monitors, which require a high refresh rate to minimize flicker, TFT technology is inherently flicker-free. If possible, configure your computer for 1600 ×1200 address ability at 60Hz vertical refresh rate.

For the display modes listed on the next page, the screen image has been optimized during manufacture.

To optimize image quality,

you may want to run AUTO

Setup after switching

between modes shown in this

section. AUTO SETUP can fix the

problems in most cases. See Auto

Setup for DOS on page 13 for

details.

Power Management

If your computer has

previously been used with a

CRT monitor and is currently

configured to a display mode

outside the range that the Flat Panel monitor can display, you may need to re-attach the CRT monitor temporarily until you have re-configured the computer, preferably to 1600 x 1200 at 60Hz.

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. There are several states as described in the table below.

As an ENERGY STAR ^® Partner, IBM has determined that this product meets the ENERGY STAR ^® guidelines for energy efficiency.

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.

Notice: This mark applies only to countries within the European Union (EU) and Norway.

This appliance is labeled in accordance with European Directive 2002/96/EC concerning waste electrical and electronic equipment (WEEE). The Directive determines the framework for the return and recycling of used appliances as applicable throughout the European Union. This label is applied to various products to indicate that the product is not to be thrown away, but rather reclaimed upon end of life per this Directive.

In accordance with the European WEEE Directive, electrical and electronic equipment (EEE) is to be collected separately and to be reused, recycled, or recovered at end of life. Users of EEE with the WEEE marking per Annex IV of the WEEE Directive, as shown above, must not dispose of end of life EEE as unsorted municipal waste, but use the collection framework available to customers for the return, recycling, and recovery of WEEE. Customer participation is important to minimize any potential effects of EEE on the environment and human health due to the potential presence of hazardous substances in EEE. For proper collection and treatment, contact your local IBM representative.
