I'm still interested in a "selective MPRT" GPU or monitor setting, that only does black frame insertion on changed parts of an image and a "safety margin" around them. This should reduce flicker on non-moving portions of an image/still screen while keeping moving portions sharper. But this probably isn't useful for office tasks, perhaps video, and high-framerate gaming (but only games running at a lower FPS than the screen can (partially?) redraw).

For things like a pan -- you have to apply it globally because your eye movements will smear the static pixels and motionblur them across your retinas.

However, the CRT simulator actually is variable-MPRT; it does compress the light emissions as quickly as possible as early as possible. Dim greys, for example are brightened and pushed in an earlier refresh cycle of the series that simulates a CRT refresh cycle.

So dimmer pixels get lower MPRT and brighter pixels get higher MPRT. Any unemitted brightness gets cascaded to subsequent refresh cycle until fully emitted to meet Talbot Plateau Theorem.
