Brightness & Contrast

HP 25f B & C by Dr NCX, on Flickr

The HP 25f is significantly brighter than older HP modes which all failed to output more than 300cdm/2, which is fine for most viewing environments.  The 25f outputs over 450cdm/2 which makes it suitable for use with very brightly lit rooms, and possibly even outdoor use as long as the monitors screen is turned away from the sun.  The 1200:1 contrast is above average (1500:1 is outstanding while 1200:1 is great) for a modern AHVA/IPS/PLS panel, but still way too low for use in a light-less room, especially if the brightness is set above 5 (100cdm/2).  If the brightness is set to zero the HP can be used in a light-less room, but may still be a bit to bright for some since it can only dim down to 74cdm/2.

Like most other 1080p IPS/PLS panels, the HP 24 Envy, HP CW, er, es, f and XW monitors have frame-less casings which have inner black glossy bezels or frames which reduce 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.
