Permanently unlit or lit pixels

The standard of production techniques today cannot guarantee

an absolutely fault free LCD display. A few isolated permanently

lit or unlit pixels may be present. The maximum permitted

number of pixel faults is stipulated in the stringent international

standard ISO 13406-2 (Class II).

Example:

A 17” ﬂat-screen monitor with a resolution of 1280 x 1024

has 1280 x 1024 = 1310720 pixels. Each pixel consists of

three subpixels (red, green and blue), so there are about 4

million dots in total.

According to ISO 13406-2 (Class II), a maximum of 6 pixels and

7 subpixels may be defective, i. e. a total of 25 faulted dots. This

corresponds to approx. 0.002 % of the entire screen surface.

Visual Inspection

This monitor conforms to the VESA DDC (Display Data

Channel) standard, which means that when it is used with a

DDC compatible video card, the monitor is easier to set up.

With VESA DDC 1/2B, when the monitor is turned on, it will

automatically notify a windows 9X/2000/XP host computer of its

scanning frequencies, capabilities and characteristics. Windows

9X/2000/XP will automatically recognize the presence of the

monitor and select the appropriate display resolution.
