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

• The recommended viewing distance between the eye and the monitor screen is l.5xthe diagonal of the screen. Solutions in meeting this required distance in cramped office situations include pulling the desk away from the wall or divider to make roomfor monitor, using flat panel or compact displays placing the monitor in the desk corner, or placing the keyboard in an adjustable drawer to create a deeper working surface.y
• 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 adjustment, you might have to place books or other sturdy objects under the base of the monitor to achieve the desired height. A general guideline is to position the monitor such that the top of the screen is at or slightly below your eye height when you are comfortably seated. However, be sure to optimize your monitor height so the line of site between your eyes and the centre the monitor suits your preferences for visual distance and comfortable viewing when your eye muscles are in a relaxed state.y
• Tilt : Adjust the tilt of your monitor to optimize the appearance of the screen content and to accommodate your preferred head and neck posture.y
  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 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 pages 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 provides to accommodate changes in posture.
  Short, periodic breaks help ensure healthy computing: Because computing is primarily a static activity, it is particularly important to take short breaks from your work. Periodically, stand up from your work area, stretch, walk for a drink of water, or otherwise take a short break from using your computer. A short break from work gives your body a welcome change in posture and helps to ensure you remain comfortable and productive while you do work.

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.
• The monitor adopts Flicker-Free technology, which clears the eye visible flicker , brings comfort viewing experience and preventing users suffer from eye strain and fatigue.
• 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 reattach the CRT monitor temporarily until you have re-configured the system; preferably to 1920 x 1200 at 60 Hz, which is the Native Resolution Display mode.
• The display modes shown below have been optimized at the factory.
