Stephen King has made large charitable donations without announcing them because he was “raised firmly to believe that if you give away money and you make a big deal of it so that everybody sees it, that’s hubris. (…) you’re not supposed to make a big deal about it.”
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?
