Preface
Lighting
Proper lighting and a comfortable viewing angle can reduce eye strain and shoulder and neck muscle fatigue.
• Position the display to avoid glare or reflections from overhead lighting or outside sources of light.
• Keep the display screen clean and set the brightness and contrast to levels that allow you to see the screen clearly.
• Position the display directly in front of you at a comfortable viewing distance.
• Adjust the display-viewing angle to find the best position.
LCD Screen Care
To prevent image persistence on LCD monitors (caused by the continuous display of graphics on the screen for
an extended period of time) take the following precautions:
• Set the Windows Power Plans to turn the screen off after a few minutes of screen idle time.
• Use a rotating, moving or blank screen saver (this prevents an image from being displayed too long).
• Rotate desktop background images every few days.
• Turn the monitor off when the system is not in use.
LCD Electro-Plated Logos
Note that in computers featuring a raised LCD electro-plated logo, the logo is covered by a protective adhesive.
Due to general wear and tear, this adhesive may deteriorate over time and the exposed logo may develop sharp
edges. Be careful when handling the computer in this case, and avoid touching the raised LCD electro-plated
logo. Avoid placing any other items in the carrying bag which may rub against the top of the computer during
transport. If any such wear and tear develops contact your service center.
