Perceived Black Depth

All of the HP monitors have fake border-less or frame-less casings with inner black bezels which ruin the perceived black depth since the darkest black the monitors are capable of displaying is much brighter than that of the casings.  Grey and silver casings help improve the perceived black depth, as well as don't look nearly as out of place as white casings do with most computer and display accessories such as desks, keyboards, mice and receivers. 

The 24 Envy has a four sided black bezel and semi-glossy coating which puts it in last place in terms of perceived black depth and it also has the lowest measured contrast ratio of 1000:1 versus 1000-1200:1 after calibration for the other HP monitors.  Proper display height paired with less than 100 nit or cdm/2 display brightness with a 2500 lumen bias light and no other light sources results in bezel blending perceived black depth from all the monitors, and no glare or reflections either.  I have multiple articles and videos about bias lighting, display brightness and proper display height.  The top of AHVA/IPS/PLS panels needs to at least match up with the viewers eyes, and ideally line up with the top of the viewers head to eliminate off angle vertical glow. 

The semi-glossy coating used by the 24 Envy further reduces the perceived black depth under bright lighting.  I put non-stick silver tape (3$ CAD for a roll) over the bezel to trick my eyes, or increase the perceived black depth vastly, however I still highly recommend only using the 24 Envy with bias lighting, which is a light(s) placed behind a display.
