Plug & Play DDC2B Feature
This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD. It allows the monitor
to inform the host system of its identity and, depending on the level of DDC used, communicate additional information
about its display capabilities.
The DDC2B is a bi-directional data channel based on the I²C protocol. The host can request EDID information over the
DDC2B channel.

LCD Monitor Quality and Pixel Policy: HP w19 LCD Monitor

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 response rate, from a distance of approximately 50 cm (16 in).
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.
