This Steemit article and video are guides for finding out how much light, and what type of lighting one needs to ensure dark perceived black depth from a display with decent uniformity (minor back-light bleed or less) and >800:1 contrast. Dark perceived black depth refers to ensuring black looks black, not greyish in dark content. A specific, but different amount of bias (light behind the display) and normal room lighting (ceiling or lamp) is required to increase increase the displays increased black depth or hide its lack of black depth, glow and light bleed, especially in the case of displays with low contrast.

Display Brightness & Light Matching Chart For 80-250cdm/2 Display Brightness

A display with 1000:1 contrast and 80cdm/2 brightness (measured white) needs 1600 lumens of bias lighting and 1200 lumens of ceiling light while 250cdm/2 display brightness requires 5000 lumens of bias lighting and 4000 lumens of ceiling light.

VA panels with higher contrast or lower black depth need less light to increase the perceived black depth, especially if their contrast is above 3,000:1. I don't have bias and ceiling or room lighting estimates for 3,000:1 contrast, but determining what is right becomes quite obvious if one follows the first few steps from my guide.

Bezel or casing color or shade also plays a huge role in black depth perception, or how dark black looks. Grey, silver and white bezels or casings vastly increase the perceived black depth versus glass covered, glossy and matte black bezels or casings. A monitor like the Samsung S32F351 does not require very much light to increase its perceived black depth since it has a 3,500:1 contrast ratio and a glossy white bezel:
