Chapter 2 Adjusting and using your monitor 2-1

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.

Arranging your work area Use a work surface of appropriate height and available working area to allow you to work in comfort. Organize you 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 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 of the monitor suits your preferences for visual distance and comfortable viewing when your eye muscles are in a relaxed stated.

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 screens 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.

2-2 D24-40 LCD Monitor Users Guide

Health Administration Prolong exposure to computer screens may cause temporary visual fatigue. Factors including working environment, working habit and posture, screen flicker and blue light contribute to this condition. To minimize visual fatigue certain adjustments can be made on the work stations or using suitable computer screens with features that alleviate eye strain.

Environment Visual fatigue is affected by the working environment. Glare reductions and appropriate lighting situations help minimize this condition. Glare reduction Glare can be reduced by a) Changing position of any light source that is causing the glare. b) Fitting the light sources with appropriate diffusers or lampshade. c) Using curtains or blind on windows to minimize glare from direct sunlight. d) Adjusting monitor position to be perpendicular to the source of light or windows. e) Using an anti-glare screen - ThinkVision monitors have anti-glare surface treatment that

scatters light for a reflection-free work usage. Lighting Adequate lighting is necessary to avoid glare and eye fatigue. Excessive or insufficient lighting makes the display on screen harder to see. Generally, lighting level should not exceed 750 lux and levels ranging from 300 to 500 lux are most appropriate for computer desk work. Recommended lighting arrangement includes positioning work stations away from direct sunlight or using overhead lighting with baffles or louvers that reduces glare.

Working Habits Long exposures to computer screens may cause eye strain. Symptoms include headache, burning eyes, blurred vision and discomfort. To minimize eye strain, computer users can adjust working habits to let their eyes relax and recover. Break Times Computer users should take some time away from the screen especially if working for prolong hours. Generally, it is recommended to take short breaks (5 15 mins) after 1 2 hours of continuous computer works. Taking short and frequent breaks is more advised than longer breaks. Looking at Distant Objects Users often blink less when in front of monitor screen. To minimize eye strain and dryness, users should rest the eye periodically by focusing on objects that are far away. Eye and Neck Exercises Certain exercise reduces eye strain and prevent early onset of musculo-skeletal disorders. It is recommended to repeat these exercises often. However, should symptoms persists it is recommended to consult a physician.

Chapter 2 Adjusting and using your monitor 2-3

Exercises for the eye: 1. Alternate looking up and looking down while keeping the body and head upright. 2. Slowly roll your eyes to look to the left and right. 3. Roll eyes to look at objects on the upper right corner and then on lower right. Do same thing

to look at objects on the upper left and lower left. Exercises for the neck: 1. Relax arm at the side. Bend head forward to slightly stretch the neck. Hold for 5 seconds. 2. Relax arm at the side. Turn thead to the right. Hold for 5 seconds. Then turn head to the left. 3. Relax arm at the side. Swing head to the left. Hold for 5 seconds. Then swing head to the

right.

Working Posture Appropriate working position helps minimize eye discomfort. Seating position and ideal placement of monitor are essential for a comfortable working experience.

Seating Position Placing the monitor too far or too close may lead to eye strain. Far viewing distance causes users to lean forward to see small texts, which strain the eyes and torso. Close viewing distance, on the other hand, strains the eye resulting from exerting more effort to focus and also causes the user to sit in awkward body posture (i.e. tilting the head, typing with outstretched arms, etc.) Recommended viewing distance between the eye and the monitor screen is 1.5 x the diagonal of the screen. Solutions in meeting this required distance in cramped office situations include pulling desk away from wall or divider to make room for 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.

ThinkVision monitors are design to maximize work space (e.g. having thin profiles, compatible for ThinkCentre Tiny back mount, practical cable management, etc).

2-4 D24-40 LCD Monitor Users Guide

Viewing Angle Neck fatigue and pain may result from prolong turning of the head to see objects on the monitor screen. To minimize this, position the monitor directly in front so the head, neck and torso face forward to the screen. It is recommended that monitor should not be more than 35 degrees to the right or left of the head.

Monitors should also not be placed too high or too low as this contributes to awkward posture which results to muscle fatigue.

Reduce Flicker Monitor flickers refer to repeated changes in monitor light intensity. It is caused by several factors including but not limited to voltage fluctuations. Reducing flicker minimizes eye strain and headaches. ThinkVision monitors allow users to use high frequency display modes that can effectively reduce flicker.

Chapter 2 Adjusting and using your monitor 2-5

Low Blue Light Concerns on blue light affecting eye health have risen over the years. Blue light have wavelength between 300 nm to 500 nm.

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 1920x1080 at 60Hz, which is the Native Resolution Display mode.

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