I have a Samsung UA50HU7000 that would every now and again go into slow motion when it has to process darkish scenes. One can almost see how it stutters to process as it throws out lots of graining until it recovers again..? With SD channels it is even worse as it would then add ghosting on top of the graining. Donald Trump's hairdo on the SD news channels is, well, quite challenging...one cannot see any detail whatsoever, it seems like a fluffy halo on top of his head...perhaps a blessing in disguise..? Is this normal (the display, not Trump's hair), or is there something that can be done about it?
