In Birdbox there is a scene where one of the characters looks outside the house using the CCTV system it has.
The man is looking through an LCD screen and nonetheless,
he gets affected by the vision of those entities and suicides
What's a possible explanation for this scene?
The camera takes light and converts it to a digital signal that then gets processed by the screen that lits the pixels to reproduce the image. You are not looking directly to the real image, just some "light bulbs" that try to reproduce it.
Would that happened even if the screen was at a very low resolution, say, 200x200 pixels?
