    The Fujitsu-Siemens guideline is in line with the norm ISO 13406 Class 2.

    Assessment of faulty pixels on LCDs The pixel (which consists of 3 subpixels) is defective if one or more of the subpixels can't be controlled, i.e. the pixel/subpixel stays the same colour despite being instructed to change to another colour and is visible 30 cm from the LCD panel surface. Typically such defects can be seen as bright spots on dark background or dark spots on bright background. A defect white or black pixel can be seen if all 3 subpixels of a pixel are defective. (Type 1, 2). A coloured spot can be seen if there are one or more defective subpixels.(Type 3)
    Fault clusters are defined as: Two or more pixels or subpixels with faults within a 5x5 block of pixels.

    The general criteria and criteria for each LCD panel type for an acceptable amount of defective pixels is defined in the table below.

    Maximum number of faults per type per million pixels (e.g. a XGA display 1024x768 has = 768432 pixels)

    White pixel
    All three subpixels defective)
    (Type 1) Black pixel

    (Type 2) Coloured spot or subpixel
    (Green, red or blue)
    (Type 3) Clusters of
    type 3 faults Clusters with more
    than one type 1 or
    type 2 faults
    2 or less 2 or less 5 or less 2 or less 0

    Examples:
    Good: Bad:
    1. 5 coloured subpixels
    2. 2 white pixels, 2 black pixels
    and 5 coloured subpixels
    1. 6 coloured subpixels
    2. 3 white pixels
    3. 3 black pixels

    If your machine is older please use the following acceptance criteria to see whether it is covered by warranty.

    Az még nagyobb kakukk, már-már strucc.
    Még inkább az érvényes, amire céloztam: kb. nem érvényes semmi rá. Majd ha kopt fekete (fehér), akkor mehetsz reklamálni. :)
