LCD Monitor Quality & Pixel Policy
During the LCD Monitor manufacturing process, it is not uncommon for one or more pixels to become fixed in an unchanging state. The visible result is a fixed pixel that
appears as an extremely tiny dark or bright discolored spot.When the pixel remains permanently lit, it is known as a “bright dot.” When the pixel remains black, it is
known as a “dark dot.”
In almost every case, these fixed pixels are hard to see and do not detract from display quality or usability. A display with 1 to 5 fixed pixels is considered normal and
within competitive standards. For more information, see Dell Support site at: support.dell.com.
Maintenance Guidelines
Caring for Your Monitor
For best practices, follow the instructions in the list below while unpacking, cleaning, or handling your monitor:
l
To clean your antistatic screen, slightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning tissue or solution suitable for the
antistatic coating. Do not use benzene, thinner, ammonia, abrasive cleaners, or compressed air.
l
Use a slightly dampened, warm cloth to clean the plastics. Avoid using detergent of any kind as some detergents leave a milky film on the plastics.
l
If you notice a white powder when you unpack your monitor, wipe it off with a cloth. This white powder occurs during the shipping of the monitor.
l
Handle your monitor with care as a darker
-colored monitor may scratch and show white scuff marks more than a lighter-colored monitor.
l
To help maintain the best image quality on your monitor, use a dynamically changing screen saver and power off your monitor when not in use.
