Brightness & Contrast

The brightness range for both the 25er and 25es I tested ranged between 48-270cdm/2 which makes them suitable for all lighting conditions aside from the brightest such as outside on a sunny day. The contrast averaged around 1400:1 before the contrast reduction from 80 to 75 to get rid of the white bleaching, and over 1200:1 after which is still a great result for an AHVA/IPS/PLS panel.

Like most other 1080p IPS/PLS panels, the HP CW, er, es and XW monitors have frame-less casings which have inner black bezels which reduces the perceived black depth, or makes black look light (greyish) by comparison, but bias lighting (lamp placed behind the display) can be used to negate the need for reflection inducing room lights, and vastly increase the perceived black depth. I recommend putting a lamp behind the display with a 2600 lumen 6500k/Daylight CFL light (Philips example).
