Chapter 2. Adjusting and using your monitor

This section will give you information on adjusting and using your monitor.

Comfort and accessibility

Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort. Arrange your workplace and the equipment you use to suit your individual needs and the kind of work that you perform. In addition, use healthy work habits to maximize your performance and comfort while using your computer

For more detailed information on any of these topics, visit the Healthy Computing Web site at: http://www.lenovo.com/healthycomputing/

Arranging your work area

Use a work surface of appropriate height and available working area to allow you to work in comfort.

Organize your work area to match the way you use materials and equipment. Keep your work area clean and clear for the materials that you typically use and place the items that you use most frequently, such as the computer mouse or telephone, within the easiest reach.

Equipment layout and setup play a large role in your working posture. The following topics describe how to optimize equipment setup to achieve and maintain good working posture.

Positioning and viewing your monitor

Position and adjust your computer monitor for comfortable viewing by considering the following items:

- Viewing distance: Optimal viewing distances for monitors range from approximately 510mm to 760mm (20 in to 30 in) and can vary depending on ambient light and time of day. You can achieve different viewing distances by repositioning your monitor or by modifying your posture or chair position. Use a viewing distance that is most comfortable for you.

- Monitor height: Position the monitor so your head and neck are in a comfortable and neutral (vertical, or upright) position. If your monitor does not have height adjustments, you might have to place books or other study objects under the base.

• Tilt:

Adjust the tilt of your monitor to optimize the appearance of the screen

content and to accommodate your preferred head and neck posture.

- General location:

Position your monitor to avoid glare or reflections on the

screen from overhead lighting or nearby windows.

The following are some other tips for comfortable viewing of your monitor:

Use adequate lighting for the type of work you are performing.

Use the monitor brightness, contrast, and image adjustment controls, if equipped,

to optimize the image on your screen to meet your visual preferences.

Keep your monitor screen clean so you can focus on the screen's contents.

Any concentrated and sustained visual activity can be tiring for your eyes. Be sure to periodically look away from your monitor screen and focus on a far object to allow your eye muscles to relax. If you have questions on eye fatigue or visual discomfort, consult a vision care specialist for advice.

Quick tips for healthy work habits

The following information is a summary of some important factors to consider to help you remain comfortable and productive while you use your computer.

· Good posture starts with equipment setup:

The layout of your work area and

the setup of your computer equipment have a large effect on your posture while using your computer. Be sure to optimize the position and orientation of your

equipment by following the tips outlined in "Arranging your work area" on page 2-1

so you can maintain a comfortable and productive posture. Also, be sure to use the adjustment capabilities of your computer components and office furniture to best suit your preferences now and as your preferences change over time.

- Minor changes in posture can help avoid discomfort:

The longer you sit and

work with your computer, the more important it is to observe your working posture. Avoid assuming any one posture for an extended period of time.

Periodically make minor modifications in your posture to help deter any discomforts that might arise. Make use of any adjustments that your office furniture or equipment provide to accommodate changes in posture

- Short, periodic breaks help ensure healthy computing:

Because computing is

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 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 1920 x 1080 at 60 Hz, which is the Native Resolution Display mode.

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

Addressability	Refresh rate

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 rotation. Check the Graphic Properties setting on your computer to see if this feature is 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 NV Rotate, 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 with image rotation can be downloaded from their support website.

Audio description:

If your Operation System(OS) is XP, for the XP limitation, 2 phenomena will be happened:
A) The USB audio is recognized as a speaker phone by PC, Speaker volume control icon will be disappeared when you plug in the USB cable.
B) Because PC doesn't set the USB audio as the prior audio output automatically when you first plug in the USB cable, and the monitor will not audio output.

4> Select LT2223dwC as default audio output.
5> Apply it.

Understanding power management

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.

Table 2-4. Power indicator

State	Power Indicator	Screen	Restoring Operation	Compliance
On	Steady green	Normal
Standby/Suspend	Steady amber	Blank	Press a key or move the mouseThere may be a slight delay before the image reappears.Note: Standby also occurs if there is no image output to the monitor.	ENERGY STAR
		Off Off	Press the power keyThere may be a slight delay before the image reappears.	ENERGY STAR
