I know looking at a na mahram with zinah is haram in person, but is it also haram through a television if without lust. Like watching a tv show. Also if it is haram is it permissible for one to watch the show if everytime a na mahram with zinah comes up they put their hands in front of their eyes to cover part of the screen. Sometimes they may mistime putting their hands and so they may see a glimpse but they look away immediately. What is the ruling?

It is not permissible to watch such prono shows
