Optimizing Analog Video

Two controls in the on-screen display can be adjusted to improve image performance: Clock and Clock
Phase.

NOTE: The Clock and Clock Phase controls are adjustable only when using an analog input. These

controls are not adjustable for digital inputs.

The Clock must first be set correctly since the Clock Phase settings are dependent on the main Clock
setting. Use these controls only when the auto-adjustment function does not provide a satisfactory
image.

●

Clock—Increases/decreases the value to minimize any vertical bars or stripes visible on the screen
background.

●

Clock Phase—Increases/decreases the value to minimize video distortion or video jitter.

NOTE: When using the controls, you will obtain the best results by using the auto-adjustment pattern

software utility provided on the CD.

When adjusting the Clock and Clock Phase values, if the monitor images become distorted, continue
adjusting the values until the distortion disappears. To restore the factory settings, select Yes from the
Factory Reset menu in the on-screen display.

Energy Saver Feature

When the monitor is in normal operating mode, the Power light is aqua-white and the monitor uses the
normal watts of power. For power usage, refer to

Technical Specifications on page 27.

The monitor also supports a power-saver mode that is controlled by the computer. When the monitor is
in the reduced-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 power­saver feature must be activated on your computer for this feature to work.

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.

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.
