Sitting Directly In Front Is Not A Remedy

All TN panels have very restrictive viewing angles and suffer from vertical gamma shift, therefore all TN panels have bad image quality. AHVA/IPS/PLS panel glow is not a problem if viewed correctly, and not in the dark with the brightness cranked:



Since TN panels suffer from vertical gamma shift, their colors and shades are uneven from top (top quarter is too dark) to bottom (bottom half is washed out), as well tend to have more banding, and always have vastly less wide, or more restrictive viewing angles, though all LCD panel types look the worst when viewed from above, or looked down at.

It does not matter if one sits directly in front of their TN panel (correct way to view a TN), or how much one pays, especially since the majority (excluding Dell S2716DG & S2719DGF) of the most expensive 27" 1440p TN panels use grainier/sparklier matte coatings than AHVA/IPS/PLS panels. Calibration can vastly improve inaccurate TN panels, but a TN is a TN, and all TN suffer from obvious vertical gamma shift.

Dell S2716DG (AUO TN) v BenQ XL2420G (AUO TN) v Qnix QX2710 (Samsung PLS):

Calibrated with an X-Rite i1 display pro colorimeter with ICC profile activated to correct the gamma in 2015.

Calibrated but connected to a PS4 so there's no gamma correction; both monitors have non-linear and low-ish gamma below the target of linear 2.2


BenQ Zowie RL2460 (AUO TN) vs Qnix QX2710 Multi Hot (AUO AHVA):

Calibrated but connected to a PS4 so there's no gamma correction; both monitors have nearly perfectly linear 2.2 gamma and are extremely accurate.
