LCD Monitor Quality and Pixel Policy
The HP 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 the 
HP 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 improvements are made.
For more information about your HP LCD Monitor, refer to the HP Web site at: http://www.hp.com/support
Power Cord Set Requirements
The monitor power supply is provided with Automatic Line Switching (ALS). This feature allows the monitor to operate 
on input voltages between 100–240Vv, 50/60 Hz, 1.5A.
The power cord set (flexible cord or wall plug) received with the monitor meets the requirements for use in the 
country/region where you purchased the equipment.
If you need to obtain a power cord for a different country/region, you should purchase a power cord that is 
approved for use in that country/region.
The power cord must be rated for the product and for the voltage and current marked on the product’s electrical 
ratings label. The voltage and current rating of the cord should be greater than the voltage and current rating marked 
on the product. If you have questions about the type of power cord to use, contact your HP-authorized service 
provider.
A power cord should be routed so that it is not likely to be walked on or pinched by items placed upon it or against 
it. Particular attention should be paid to the plug, electrical outlet, and the point where the cord exits from the 
product.
