Could I see a difference? Sure, but it was minimal. Indeed, while higher resolution is critical for watching movies and TV shows, here it's not the most important factor.įor example, I looked at this Tropical Storm Window at various resolutions ranging from 4K on down to 720p. If your primary goal here is fake windows (and maybe some fun effects come Halloween), you definitely don't need an expensive 4K projector. Here's the question: Can you really do this with a low-price projector? Short answer: Yes, but there are things you should know - and reasons you might want to spend a little more. ( Harry Potter-inspired Hogwarts window, anyone?) Outside that window: live images of a rainforest, mountain landscape, tropical beach or the like. For as little as $60 or so, you're told, you can turn your wall into a big, beautiful picture window. But it sure looks the reason this is going viral right now is the projector part: TikTokkers claim this can be done with super-cheap models.

It's a fake one, courtesy of a cheap projector and YouTube video. That said, it's a really fun way to use a projector and leverage an empty wall - maybe one next to your bed, so you can curl up and enjoy the view, or near your dining table to spruce up a romantic evening. It's not a 'challenge' in the traditional sense - there's no need to dump a bucket of ice water over your head, for example - and not especially original, as people have been doing this for years. If you're a TikTok user, you've probably spied the latest trend: the Fake Window Challenge.
