ENWWPower-Saver Feature 15
Power-Saver Feature
When the monitor is in normal operating mode, the Power light is blue and the monitor 
uses the normal watts of power. For power usage, refer to Technical Specification 
(Appendix B). The monitor also supports a po wer-saver mode that is controlled by the 
computer. When the monitor is in the redu ced-power state, the monitor screen is 
blank, the backlight is off, and the Power light is amber. The monitor uses minimum 
power. When the monitor is awakened, a brief warm-up period occurs before the 
monitor returns to normal operating mode . The energy-saving reduced power state 
activates if the monitor does not detect either the horizontal sync signal or the vertical 
sync signal. The power- saver feature must be activated on your computer for this 
feature to work. Refe r to your computer documentatio n for instructions on setting 
energy-saver features (sometimes  called power-management features).
 NOTE:  The energy-saver feature works only when the monitor is connected to 
computers that have  energy-saver features.

LCD Monitor Quality and Pixel Policy
Your LCD Monitor uses high-precision technology, manufactured according to high 
standards, to help 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 your LCD Monitor. These imperfections are caused by one or more 
defective pixels or subpixels.
A pixel consists of one red, one green, and one blue subpixel. 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 
subpixel (dot defect) is less visible than a  defective whole pixel, and is small and only 
visible on a specific background.
To locate defective pixels, the monitor should be viewed under normal operating 
conditions and in normal operating mode at  a supported resolution and refresh rate, 
from a distance of approximately 50 cm (16 inches). We expect that, over time, the 
industry will continue to improve its ability  to produce displays with fewer cosmetic 
imperfections, and we  will adjust guidelines as im provements are made. For more 
information about your LCD Monitor,  refer to the HP Web site at: 
http://www.hp.com/support .
