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  
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 center 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:  
Copyright Lenovo 2011.  
2-1  
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 in front of your computer, the more important it is to observe your working  
posture. Avoid as summing 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  
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.

Additional Information  
The following section provides additional information on the use of the DisplayLink USB Graphics  
software.  
Monitor Calibration  
DDC/CI is not supported on displays with integrated DisplayLink technology, for example mini monitors.  
Media Playback  
On Windows 7, Vista and Windows XP (in extend modes), the DisplayLink USB Graphics device can  
display media files and DVDs using the following media players:  
Windows Media Player 11 (http://www.microsoft.com/windows/windowsmedia/default.mspx)  
WinDVD 8 (www.intervideo.com)  
PowerDVD 7 (www.cyberlink.com)  
RealPlayer 11 (www.real.com)  
The DisplayLink USB Graphics device can display media files and DVDs using most media players. Media  
playback in mirror mode (XP) or in Basic mode (Vista and Windows 7) is not recommended.  
Using Multiple DisplayLink USB Graphics devices  
The software supports up to six simultaneously USB attached screens. It is also possible that different sets  
of screens are being used at different times, for example two in the office and two at home. The software  
saves each screen’s display profile separately. This allows for different physical positioning, or different  
resolutions, of connected monitors in the office and the home.  
Standby and Hibernate, Shut down and Restart  
If the PC that the DisplayLink USB Graphics device is connected to is placed into standby or hibernate  
mode, the display goes blank. When the PC is again powered up (and unlocked if necessary) the connected  
monitor returns to the same mode as it was before stand by or hibernation.  
If the PC is shut down, restarted and logged in, again the connected display returns to the same mode as it  
was before shutdown.  
DisplayLink USB Graphics with Multiple Users  
DisplayLink USB Graphics work with multiple users on the PC. The mode settings are saved for each user  
so each can use their own desktop configuration.  
Disconnecting the DisplayLink USB Graphics  
If the DisplayLink USB Graphics device is powered off or the USB cable is removed from the computer,  
the display blanks. All windows and icons move to the primary screen.  
On reconnection or powering up of the DisplayLink USB Graphics device, the display returns to the same  
mode as it was before disconnection. However, windows and icons that were previously on the screen will  
not be moved back.

controls the internal video controller of your computer.  
The Lenovo LT1421 Wide USB Monitor utilizes an advanced video graphics controller to display  
the video. However, due to USB 2.0 transfer speed limitations, some or all portions of DVD  
playback may appear slow or choppy. This is not a malfunction of the Lenovo LT1421 Wide USB  
monitor. Move the video playback from the Lenovo LT1421 Wide USB monitor to your computer  
display for optimal video performance when viewing DVDs.  
On Windows® XP systems, DVDs may not display correctly on the Lenovo LT1421 Wide USB  
monitor. Use your computer's built-in monitor to view DVDs.
