you have opened a can of worms:
1) would a new 4k transfer make the curse worse?
2) If the video were watched on a full sized theater screen, would she be a giant?
3) If you watched the video on your smart phone, would she be very small, like a smurf?
4) If you watched the video with a virtual realty headset, would she crawl directly into your eye sockets?
5) If someone watches the video but cant really see( legally blind, near sighted, or far sighted), does that count?
6) what if a monkey or a hamster watches the video?
Based on the 1st two U.S. movies:
1) Probably not. TV's seem to act like a window to her nightmare world. A dirty window doesn't make a storm worse does it?
2-4) She doesn't attack when you watch the video; she attacks later on. She'd probably pick a screen of the right size when the attack happens. Now what happens if you remove all TV's from your house and lock yourself in?
5) It wouldn't count; a girl was able to avoid being cursed by closing her eyes when the video was playing in the 2nd movie.She was still scarred for life; her boy friend was showing her the movie to move the curse on just before his time was up. (Not nice!)
6) They'd probably go mad, like the horse on the ferry in the 1st movie.
