LCD Monitor Quality and Pixel Policy

LCD Monitor Quality and Pixel Policy

HP uses selected high quality panels for the manufacture of its LCD monitors. Nevertheless, the display may have cosmetic imperfections that appear as small bright or dark spots. This is not specific to HP but linked to the current state of the art of LCD manufacturing.

In fact, an LCD screen is made of millions of small “sub-pixels” that are each turned on or off by a transistor and it is extremely difficult to manufacture millions of perfect transistors on a large surface. Therefore, no manufacturer can currently guarantee 100% defect- free panels at a reasonable price.

How visible a defect is depends on its nature an location.

Each pixel is made up of one red, one green and one blue sub-pixel.

•A defect in a sub-pixel is not very visible, and can often only be perceived against specific backgrounds.

•Adjacent sub-pixel defects are more visible than “geographically dispersed” defects.

•A full-pixel defect (all three R/G/B sub-pixels always on or always off) is quite visible.

HP does not accept any full-pixel defects upon shipment. The vast majority of monitors do not have visible imperfections. On the other hand, HP is obliged - for the reasons outlined before - to accept the possibility of a few sub-pixel defects.

HP has established clear standards for the maximum number of imperfections per panel that can be tolerated. Your display has been checked to comply with these standards.

If you are interested in the technicalities you can find the details of HP’s pixel policy below.

Details of HP’s Pixel Policy

To identify defective pixels, the monitor should be viewed under normal operating conditions, preferably in its native resolution, and from a normal viewing distance of at least 50 cm (16 in.).
