Trying to relax by watching a movie

Most of the time, when we are tired of work or stressed out, it is advisable we take a rest, eat, and relax with something entertaining, either movies or music. During the day, I try my best to relax, and I try to watch movies via TV, which I couldn't watch via the TV. Watching movies on the TV, it was as if I was stressing my eyes and forcing myself to get attracted to the movie, but when I carried my phone, I was able to watch movies via my phone, and I stream the same movie playing via the TV on YouTube. I don't know why most of the time I do feel like that or if you have also experienced such a thing before.
