Entering User Modes
The video controller signal may occasionally call for a mode that is not preset if:
You are not using a standard graphics adapter.
You are not using a preset mode.
●
●
It this occurs, you may need to readjust the parameters of the monitor screen by using the on-screen
display. Your changes can be made to any or all of these modes and saved in memory. The monitor
automatically stores the new setting, then recognizes the new mode just as it does a preset mode. In
addition to the factory preset modes, there are at least ten user modes that can be entered and
stored.

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 improvements
are made.
For more information about your LCD Monitor and pixel policy, refer to the HP Web site at:
http://www.hp.com/support. To find pixel policy information on the HP Web site, type in "HP Pixel
Policy" in the search box and press Enter.
