Dell E248WFP Monitor - Manual (Page 8)

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.
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, lightly 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 lightly-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 darker -colored plastics may scratch and show white scuff marks more than lighter-colored monitor.
