I would not consider that good enough I run 16 intensity levels and (fortunately only) one customer has asked for a finer granulation.

Erik

That is 16 base intensities times n bits of RGB modulation?

For a monochrome on/off sign (all diodes off or lit with uniform intensity), I step the intensities in 0.01% steps to make sure that the individual steps are not visible during pitch-black night when the display may step down to maybe 0.01 of max intensity. So next higher intensity level will be 0.0101.
