Chapter 2. Adjusting and using your monitor

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

Comfort and accessibility

Good ergonomic prac tice is important to get the most from your pers onal computer
and to avoid discomfort. Arrange your workplace and the equipm ent you use to suit
your individual needs and the kind of wor k that you perform. In addition, use healthy
work habits to maximize your performa nce and comfort while using your computer

.For more detailed information on any o f these topics, visit the Healthy Computin g
Web site at:

http://www.lenovo.com/healthycomputing/

Arranging your work area

Use a work surface of appropriate heigh t and available working area to allow you to
work in comfort.
Organize your work ar ea to match the way you use materials and equipm ent. Keep
your work area clean and clear for the mate rials that you typically use and place the
items that you use most frequently, such as the computer mouse or telephone, wi thin
the easiest reach.
Equipment layout and setup play a large role in your working postur e. The following
topics describe how to optimize equip ment setup to achieve and maintain good
working posture.

Positioning and viewing your monitor

Position and adjust your computer mon itor for comfortable viewing by consider ing
the following items:

· Vie wing distance: Optimal viewin g distances for monitors range from
approximately 510mm to 760mm (20 in to 30 i n) and can vary depending on
ambient light and time of day. You can achieve different viewing distances by
repositioning your monitor or by modi fying your posture or chair position. Use a
viewing distance that is most comfort able for you.

· Moni tor height: Pos ition the monitor so your head and neck are in a com fortable
and neutral (vertical, or upright) po sition. If your monitor does not have height
adjustments, you might have to place bo oks or other sturdy objects under the base
of the monitor to achieve the desired hei ght. A general guideline is to posit ion the
monitor such that the top of the screen is at o r slightly below your eye-height
when you are comfortably seated. Howe ver, be sure to optimize your monitor
height so the line of site between your eye s and the center the monitor suits your
preferences for visual distance and c omfortable viewing when your eye muscles
are in a relaxed stated.

Tilt:

Adjust the tilt of you r monitor to optimize the appearance of the sc reen
content and to accommodate your prefe rred head and neck posture.

· Gene ral location:
Position your monitor to avoid glare or r eflections on the
screen from overhead lighting or near by windows.
The following are some other tips for com fortable viewing of your monitor:

· Use adequate lighting for the type of wor k you are performing.

· Use the monitor brightness, contras t, and image adjustment controls, if equip ped,
to optimize the image on your screen to mee t your visual preferences.

· Keep your monitor screen clean so you can f ocus on the screen’s cont ents.
Any concentrated and sustained visu al activity can be tiring for your eyes. Be sure t o
periodically look away from your moni tor screen and focus on a far object to allow
your eye muscles to relax. If you have ques tions on eye fatigue or visual discomfort,
consult a vision care specialist for ad vice.

Quick tips for healthy work habits

The following information is a summar y of some important factors to consider to
help you remain comfortable and produ ctive while you use your computer.

· Good p osture starts w ith equip ment setup:
The layout of your work area and

the setup of your computer equipment ha ve a large effect on your posture while
using your computer. Be sure to optimize the position and orient ation of your
equipment by following the tips outli ned in “Arranging your work area” on page 2-1
so you can maintain a comfortable and pro ductive posture. Also , be sure to use the
adjustment capabilities of your com puter components and off ice furniture to best
suit your preferences now and as your pre ferences change over time.

· Mino r changes in post ure can help avoid discomf ort:
The longer you sit and
work with your computer, th e more important it is to observe your working
posture. Avoid assuming any one posture for an e xtended period of time.
Periodically make minor modificat ions in your posture to help deter any
discomforts that might arise. Make us e of any adjustments that your office
furniture or equipment provide to acc ommodate changes in posture

· Shor t, periodic bre aks help en sure healthy co mputing :
Because computing is
primarily a static activity, it i s particularly important to take short bre aks from
your work. Periodically, stan d up from your work area, stretch, walk for a drin k of
water, or otherwise take a sh ort break from using your computer. A short break
from work gives your body a welcome chang e in posture and helps to ensure your
emain comfortable and productive wh ile 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.
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.
