My collection of backlightbleed photos

[nightrhyme]

Can you buy a Samsung 2232bw & Hazro HZ26W too and compare please

PS I've had mine for 6 months-ish and just found out what the LED Brightness did lol

Sorry those monitors pose no interest for me
There's only one monitor left I would like to give a test ride: NEC 2690Wuxi

You actually made me make my room completely dark again and view fullscreen black and compare it to my picture

In dark room you should keep image as black only for few seconds because after that eye gets adapted to dark and shows everything brighter than it would show with say movie using most of the screen.
(human vision system doesn't measure absolute brightness but contrast)

So lowest black level values measured by calibrators are best even somewhat consistent method for evaluating backlight leakage.
Those results can be partially compared to those with just image: For example cheap displays which don't have backlight brightness adjustment have always bad black level/backlight bleed. Now we also know that "high end" Hazros don't have backlight brightness adjustment so backlight bleed of those is probably equally bad.
As downside these measured values don't take variations around screen into account, like higher edge bleeding commonly found in TNs.
