If you want to put a projector on the bedside table in the bedroom, whether it is short focus or sid

If you want to put it on the bedside table in the bedroom, it is generally about 2-3 meters away from the wall (depending on the actual situation), and the screen will be enlarged to 60 inches-80 inches, and the short focus will be enlarged to more than 100 inches. Using a short-throw screen that is too large is uncomfortable to look at (like you're sitting in the front row of a movie theater) and will lead to a lack of brightness and reduce the experience. Secondly, if the bedside table is on both sides of the bed instead of above the head, if you want to see the picture in the middle, there will inevitably be a trapezoid on the left and right sides of the screen, and you need to have a trapezoidal correction function (see the figure below).

Therefore, it is recommended to use side projection, and short throw is not recommended.

Hoisting can be considered, and in the bedroom, it can be considered to be configured according to hoisting.

Short focus is to achieve a large screen at a short distance, generally placed at the end of the bed can achieve a 100-inch large screen, if placed at the head of the bed may have to be put into 200 inches, but the available wall in your home may not be so big and the brightness will be reduced.

Generally, the projector with high brightness and high resolution is also large, and it is difficult to put it at the head of the bed, and the space that can be placed is only on the bedside table, so in comparison, if you do not have a reserved place at the head of the bed, choose the side projection on the bedside table.
