Appendix) all reliabilities are specified for timing specification based on refresh rate of 60Hz.
However, LP121WX4 has a good actual performance even at lower refresh rate (e.g. 40Hz or 50Hz)
for power saving mode, whereas LP121WX4 is secured only for function under lower refresh rate.
60Hz at Normal mode, 50Hz, 40Hz at Power save mode. Don’t care Flicker level (power save mode).
