HP ZR30w 30-Inch S-IPS LCD Monitor Review
Everest Image Quality Testing
We put the HP ZR30w through an assortment of monitor diagnostics using Everest Ultimate Edition from Lavalys. These tests provide key patterns that allow us to evaluate various aspects, such as color accuracy, and uniformity. The tests are really designed to help you calibrate your monitor, but in our case, we used them the gauge image quality from the ZR30w as it ships from the factory.

Monitor Diagnostic Screens
Everest provides several tests to help you calibrate and check your monitor for imperfections, and we ran the ZR30w through all of them. With few exceptions, HP's display strutted through the tests with confidence. It was difficult to find any weak spots, with the ZR30w performing exceptionally well in the geometry tests. Colors transitioned well, as they should on a high end display, and did so at a variety of viewing angles, which is one of the strengths of an S-IPS panel.
In terms of dead pixels, we didn't find any with our test sample. For monitors produced after May 2009, HP's warranty allows for the following:
| Bright sub-pixel defects |
2 maximum |
| Dark sub-pixel defects |
5 maximum |
| Total combined bright and dar sub-pixel defects |
5 maximum |
| Full Pixel Defects pixel defects |
0 allowed |
For more information on HP's Pixel Policy, as well as expanded explanations about the various types of defects listed above, see here.
