Colour monitor B15-1

Permanently unlit or lit pixels	The standard of production techniques today
	cannot guarantee an absolutely fault-free screen
	display. A few isolated constant lit or unlit pixels
	may be present. The maximum permitted
	number of pixels faults is stipulated in the
	stringent international standard ISO 13406-2
	(Class II).
	Example: a 15" flat-screen monitor with a
	resolution of 1024 x 768 has 1024 x 768 =
	786432 pixels. Each pixel consists of three
	subpixels (red, green and blue), so there are
	about 2.4 million dots in total.
	According to ISO 13406-2 (Class II), a maximum
	of 4 pixels and 5 subpixels may be defective, i.
	e. a total of 17 faulted dots. This corresponds to
	approx. 0,002% of the entire screen surface!
