Pixel Defect Policy - Philips BDL5551EL/00 Service Monitor

• The PC text quality is optimum in HD 1080 mode (1920 x 1080, 60Hz).
• Your PC display screen might appear different depending on the manufacturer (and your particular version of
Windows).
• Check your PC instruction book for information about connecting your PC to a display.
• If a vertical and horizontal frequency-select mode exists, select 60Hz (vertical) and 31.5KHz (horizontal). In some
cases, abnormal signals (such as stripes) might appear on the screen when the PC power is turned off (or if the
PC is disconnected). If so, press the [INPUT] button to enter the video mode. Also, make sure that the PC is
connected.
• When horizontal synchronous signals seem irregular in RGB mode, check PC power saving mode or cable
connections.
• The display settings table complies to the IBM/VESA standards, and based on the analog input.
• The DVI support mode is regarded as same to the PC support mode.
• The best timing for the vertical frequency to each mode is 60Hz.

4.3 Pixel Defect Policy

We strive to deliver the highest quality products and use some of the industry's most advanced manufacturing
processes whilst practicing stringent quality control. However, pixel or sub-pixel defects on the PDP / TFT panels
used in Plasma- & LCD- displays are sometimes unavoidable. No manufacturer can guarantee that all panels will
be free from pixel defects, but Philips guarantees that any Plasma- & LCD- displays with an unacceptable number
of defects will be repaired during the warranty period in line with your local guarantee conditions.
This notice explains the different types of pixel defects and defines the acceptable defect level for the LCD screen.
In order to qualify for repair under warranty, the number of pixel defects must exceed a certain level as shown in
the reference table. If the LCD screen is within specification a warranty exchange / claim back will be refused.
Additionally, because some types or combinations of pixel defects are more noticeable than others, Philips sets
even higher quality standards for those.
Pixels and Sub-pixels
A pixel, or picture element, is composed of three sub-pixels in the primary colors of red, green and blue. Many
pixels together form an image. When all sub-pixels of a pixel are lit, the three colored sub-pixels together appear as
a single white pixel. When all are dark, the three colored sub-pixels together appear as a single black pixel. Other
combinations of lit and dark sub-pixels appear as single pixels of other colors.
