HP 24 Envy Calibration Chart

The Blue setting needed to be greatly reduced from 255 to 219, but this left the monitor with an obvious green tint to white and some shades of grey. Reducing the Green setting from 255 to 247 and Red from 255 to 254 fixed the green dominance and left the HP looking very natural and neutral, and of course, accurate.

The HP 24 Envy is capable of covering 99% of the sRGB color space after calibration which is an excellent result for a budget monitor, and a superior result to the 25-27 HP CW/er/es/XW monitors which peaked at 94-98%. The 24 Envy's very accurate colors combined with the clarity and vibrancy reducing Low Haze coating provide a beautiful, but still flawed picture due to the thin black vertical lines visible on some light blue and orange shades.

The HP 24 Envy also looks a bit washed out when used with bright lighting due to its "frame-less" black bezel which the monitors high (versus OLED & Plasma) black level or low contrast (1,000:1) can not compete with. When the lights are off the HP looks even worse along with 99% of LCD panels which display black is greyish due to their low contrast, especially if their brightness is kept high in a light-less room.

When used with bias lighting (light placed behind the display) the HP 24 Envy looks beautiful since it, along with the majority of displays look much better when no light is penetrates the coating. Black blends with the glossy black frame-less bezel when used with my 4000 lumen 5000k LED light (example) and 5000 lumen 6500k CFL light (example) when the monitor's brightness is lowered to output 140cdm/2. Both of these lights cost 50$ Canadian, but they are essentially a one time investment which vastly improves the display viewing experience when used as a bias light since bias lighting eliminates reflections and vastly increases the perceived black depth of displays. Cheaper and dimmer bias lights can be used, but display brightness must be lowered to be used with dimmer lights. I use 140cdm/2 display brightness since it works well with a bright bias light and 2500 lumen ceiling light while <90cdm/2 display brightness functions well with 1500 lumen bias and ceiling lights.
