my recommended settings (these are also kernel default settings):
CPU: 2265mhz - 300mhz; interactive; 2 (always active cores on touch)
GPU: 450mhz - 200mhz; msm-adreno-tz
Storage: fiops; 512kb (for both)
These settings are optional:
Display: Black level: 1,56% (max); White: FF F0 FF (for a warmer white point)
This happens to black level and causes the black crush effect: check here, the first 8 steps are not distinguishable, with the small increase above 1.5% you can almost recognize the first step.[...]One thing about the S4 is that the Samsung color profiles will crush everything below 1.5% or someone would call 1.5IRE.
i950X devices have an issue with the AMOLED controller in which, if individial pixels get power-gated for true black, they occur a latency delay when getting powered on again, resulting in a visible smearing effect.
Acts on the black RGB channel filters of the mDNIe engine to elevate pure black to a deep grey. Acts as single control; it acts as a luminosity addend to all greyscale colours in 0.39% steps.
A value of 3 or 4 should be satisfactory to remove the smearing.
