HP pavilion f2304 Manuale Utente

The HP f2304 monitor uses high-precision technology 
manufactured according to HP standards, to guarantee 
trouble-free performance. Nevertheless, the display may 
have cosmetic imperfections that appear as small bright or 
dark spots. This is common to all LCD displays used in 
products supplied by all vendors and is not specific to the 
HP f2304 displays. These imperfections are caused by one 
or more defective pixels or sub-pixels.

■

A pixel consists of one red, one green, and one blue 
sub-pixel.

■

A defective whole pixel is always turned on (a bright 
spot on a dark background), or it is always off (a dark 
spot on a bright background). The first is the more visible 
of the two.

■

A defective sub-pixel (dot defect) is less visible than a 
defective whole pixel and is small and only visible on a 
specific background. 

The HP display does not have more than:

■

5 total defects — combination of full pixel and sub-pixel 
defects

■

3 defective bright sub-pixels

■

5 defective dark sub-pixels

■

Bright dots must have a 15 mm minimum separation

■

Bright dot to dim dot must have a 5 mm minimum 
separation

■

Dim dot to dim dot must have 5 mm minimum separation
