Samsung calls it MPA on their monitors, Smooth Motion Driver on their TVs, LG calls it Motion Picture Improvement Technology on their TVs, Mirai (CMO) hasn't given it an official name yet, but for us this is all the same thing. Manufacturers are betting on a doubled amount of images in computer monitors and in TVs to reduce – or even as they say remove – the afterglow effect. 60 Hz LCDs would increase to 120 Hz to display two times more images as they produce today: European TVs currently at 50 Hz would increase at 100 Hz and US from 60 Hz to 120 Hz.

If we only stick to the manufacturers announcement without questioning them (we will do that later when we will have the products in hand), the afterglow reduction would also come from new backlights that are capable of synchronizing their frequencies to the images. There is also sometime on top a system inspired by CTR monitors and TV: the introduction of an artificial images scanning.

LG : the two monitors presented are said to include the same panel. The only difference would be the image frequency and backlights.
The scanning has been developed by Samsung for the first generation of TVs with LED backlight. Images are no longer drawn in full frames but in successive groups of lines proceed by a black stripe of several lines. This area without image would, according to the manufacturer, "clean" our eyes from the natural retinal persistence. This theme is also evoked by BenQ in the BFI technology.

Samsung's TV LED including image scanning is on the right, on the left a LED TV without scanning. We guess the black stripe in movement on the right.
