In your room, a space under the bed is enough to make the TV disappear after viewing. But not only that. Lack of fitted walls or unalterable furniture can make it difficult or aesthetically disharmonious to install a TV. Furthermore, thanks to the very high definition of 4K and 8K panels, only 170 cm is needed for optimal viewing from a 48" TV. Why mount it on a wall?
The room gains in space, usability and order, and you don't miss out on the view of your favourite scenery.
