Strength—
Strength = % brightness reduction for this block (0 = none, 60 = −60%). The slider overrides the default algorithm value; tune each block until it looks "power-saving yet imperceptible".

Overall strength ×1.00×
Slope limit0.20
Max gain difference between adjacent 6×6 cells (applied before interpolation). Lower = smoother brightness transitions (less perceptible), slightly less saving. 0.25 = off.
