Perceived Black Depth

Refer to the Glossy Coating section of the review to see the Acer compared to other glossy-type monitors with my bright 2200 6500k LED ceiling light on.  The Acer's white bezel increases the perceived black depth enough that I was able to set my three LIFX BR30 lights to dark red and output less than 1500 lumens total and still perceive black as pure, dark and inky rather than greyish, and not see any obvious back-light uniformity issues.  Normally I need to use over 3000 lumens (maximum LIFX BR30 brightness is 1100 lumens at 3500k) with monitors with 1,000:1 contrast and fake bezel or frame-less inner black bezels and glossy black bezels.  The brighter the bias lighting the harder it is to see details on screen which is why being able to use significantly less, as well as more atmospheric lighting while also retaining inky perceived black depth a fantastic and viewing enhancing feature to have.

My Qnix UHD32R uses the same coating and has a silver bezel which increases the perceived black depth, but not as much as a white bezel since its silver bezel is darker, and because the Qnix has 30% lower contrast and obvious back-light bleed which can be seen in the Back-Light Bleed section of the review.

The Acer suffers from a bit of back-light bleed in the bottom left corner, but other wise offers above average perceived black depth thanks the the low glow panel and white bezel.  These perceptual benefits are hard to capture on camera, especially the low glow panel when photographing and viewing the monitor from a stationary position.  The BenQ Zowie RL2460 uses one of the highest quality TN panels around which is superior to the majority of TN panels on the market, including vastly more expensive 27" 1440p TN panels.

The HP Spectre 32 has low gamma averaging under 2.1 which results in colors and shades appear lighter or washed out compared to the other monitors.

The Samsung reduces the brightness when displaying very dark content including this screen shot from the PS4 exclusive The Order 1886.  The sides of the Samsung look blue-ish, lighter and washed out since VA panels suffer from horizontal gamma shift which causes their gamma to decrease the further away from the center the image is.
