LCD Monitor Quality and
Pixel Policy for f1503 Monitor
f1503 15-inch monitor
The HP f1503 TFT 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 f1503 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 f1503 display does not have more than:
• 5 total dot defects.
• Zero defective full pixels.
• 3 bright sub-pixels (red, green or blue; always on).
• 5 dark sub-pixels (red, green or blue; always off).
• No more than two adjacent (less than 2.5 mm edge-to-edge)
defective pixels.
• No more than two pairs of two adjacent defective pixels.
To locate defective pixels, the monitor should be viewed under
normal operating conditions, in normal operating mode at a
supported resolution and refresh rate, from a distance of
approximately 50 cm (16 in.).
HP expects that, over time, the industry will continue to improve its
ability to produce displays with fewer cosmetic imperfections and HP
will adjust guidelines as improvements are made.
