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 recognized the new mode just as it does a preset mode. In addition to the factory preset modes, there are four user modes that can be entered and stored.
Energy Saver Feature
When the monitor is in normal operating mode, the Power light is green and the monitor uses the normal watts of power.
The monitor also supports a reduced power state. The reduced power state will be entered into if the monitor detects the absence of either the horizontal sync signal and/or the vertical sync signal. Upon detecting the absence of these signals, the monitor screen is blanked, the backlight is turned off, and the power light is turned amber. When the monitor is in the reduced power state, the monitor will utilize less than 2 watts of power. There is a brief warm up period before the monitor will return to its normal operating mode.
Refer to the computer manual for instructions on setting energy saver features (sometimes called power management features).
NOTE: The above power saver feature only works when connected to computers that have energy saver features.
By selecting the settings in the monitor's Energy Saver utility, you can also program the monitor to enter into the reduced power state at a predetermined time. When the monitor's Energy Saver utility causes the monitor to enter the reduced power state, the power light blinks amber.

32 Appendix C Agency Regulatory Notices ENWW
D LCD Monitor Quality and Pixel Policy
The 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 LCD. 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.
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 (20 in).
HP expects that, over time, the industry will continue to improve its ability to produce LCDs with fewer cosmetic imperfections and HP will adjust guidelines as improvements are made.
