Test results colour temperature and fidelity
Colour fidelity is one of the selling points of the LG IPS277L-BN, at least LG promises a lot in this area. We tested it with out-of-the-box settings.
Native colour temperature
The temperature of 6,562 K is almost perfect.
Deviation from ideal colour temperature
It performs very well compared to similarly prices monitors.
Deviation from ideal greyscale gamma
The value of 2.2 is exceptionally low, again the IPS277L-BN is at the top of the chart.
The greyscale deviation is one of the lowest that we've ever measured, which is an indication of exceptional colour fidelity. LG's claim of calibration seems to be warranted. The human eye cannot detect any colour deviations with value of less than three.
