A stray dog saved a woman after she crashed down an embankment and was thrown through the back window of her car. The German Shepherd emerged from the woods, pulled her by the collar off the trunk and 50 yards through the briars to the road where she could be seen by passing motorists.
CRT's have a long afterglow so has plasmas, so there is defenetly no flicker as the cause of dogs not being "able" to see TV.
LCD's on the other hand was much hated at first because they could'nt refresh fast enough and that made them flicker.
Back then pc graphics cards didnt have refresh rates past 70Hz because there was no "need" for it as the CRT's could'nt keep up.
100 years ago some films was done in 16 pictures/second, does that mean that we cant see then because we would "only" see flicker?
