Perceived Black Depth & Back-Light Bleed

DSC_1063-2 by Deepinthesky Teslastorm, on Flickr

Some of the pictures look a bit different since I took the monitor apart and put silver tape under the main bezel to cover the inner black bezel.  Without the tape mod the perceived black depth and contrast of the UHD32R is excellent (when viewed correctly*), despite the low 700:1 contrast ratio.  The dark perceived black depth is a result of the glossy coating and silver bezel.  Even in the dark the silver bezel helps increase the perceived black depth and negate the need for very bright bias lighting, even though my unit suffers from obvious back-light bleed. 

*The top of AHVA/IPS/PLS panels need to line up or be higher than the top of the viewers eyes to avoid seeing glow, and sitting to close can also result in obvious glow in the bottom corners.  I sit around 2.5-30ft or 75-90cm away from the Qnix which sits on a box on my desk.  When on top of the box the top of the Qnix sits around 10cm above my head.  The photos are from my Back Light 25s Exposure album which contains photos of many more monitors.

The HP Spectre 32 has low gamma averaging under 2.1 resulting in washed out colors.

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.
