+Excellent build quality
+Very adjustable
+Matte bezel
+HDMI, Dual-Link DVI and Displayport
+4x USB 3.0 Ports
+Semi-glossy or nearly grain free matte coating
+Very fast pixel response times with minimal overshoot
+950-1000:1 contrast from 0-100% Brightness
+Near-perfect preset color accuracy, color saturation and shadow detail
+No discernible preset color tint=neutral, tint free whites
+Excellent calibrated color accuracy (100% sRGB color space coverage)
+Fairly even measured screen uniformity
+Slightly less glow vs. previously reviewed 27" 1440p monitors, except for my glow free Qnix QX2710
+Wide viewing angles
+1080p/24hz Blu-Ray support
-Hybrid Dimming=Only PWM/Flicker Free Down to 30%/172cdm/2 brightness
-Lowest PWM/Flicker Free brightness is far too bright for dark room use
-250hz PWM from 0-14% brightness
-Should use the same glow free panel as the Eizo EV2736W
-Matte black bezel makes blacks look light by comparison
-Bottom silver bezel makes blacks look much darker near the bottom of the display
-Inconsistent measured screen uniformity
-24-28ms delay
-AV mode color presets are poor
-Useless Cinema, Dynamic and Game Magic Bright settings
-Game Mode=horrible and does not improve the monitors gaming performance
-Costs more (in some countries) than the BL2710PT which is better
 
The Samsung S27D850T has the best color accuracy out of all of the monitors I have reviewed, but poor perceived black depth and black uniformity since it uses a matte black and silver bezel. The S27D850T only distinguishes itself from the pack thanks to its irrationally designed, perceived black depth running bezel and use of LED PWM Dimming when the brightness is set below 30%, and neither of these features are good.
 
It has balanced overdrive with very fast pixel response times and almost no overshoot ghosting, but so do the similarly priced, LED PWM Dimming/Flicker Free AOC Q2770QPU and BenQ BL2710PT, both of which have logical, matte grey bezels, excellent build quality, less input lag and only slightly worse color preset accuracy.
 
The S27D850T could be the best, affordable (<600$ in North America), multi-input, semi-glossy 27" 1440p monitor if Samsung equipped it with a matte grey bezel and spent the extra 2 cents on a completely LED PWM Dimming/Flicker Free back-light.
