TN & VA Gamma Shift

TN & VA Gamma Shift

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.

VA panels suffer from horizontal gamma shift which causes the sides of VA panel to be significantly lighter or washed out compared to AHVA, IPS and PLS panels. VA panel gamma becomes lower, and colors and shades become more washed out the further away from the center.

All VA panels suffer from black crush when viewed head on, and reveal detail when viewed off angle horizontally.  Some VA panels are worse than others, and this issue is less obvious when viewed from far away, but all VA panels suffer from obvious black crush.  Also note that the Samsung 43NU7100 has nearly perfectly linear 2.2 gamma and a semi-glossy coating while the Samsung F2380MX has slightly too low gamma (non-linear gamma below 2.2) and is matte.
