The simple answer is yes! While a wall can give you a perfectly smooth and flat surface to work on and give you some decent results, a lot of your projected light will be lost as the wall does not have a reflective surface. Projection screens are purpose built to optimise the light coming from your projector and diffuse it back to you evenly, some screens can even boost the brightness of your projector, this is called gain factor, which we will look a bit more into below.<o:p>

A projector and screen go together like spaghetti and meatballs! While you can have a projector without a screen, they are best together. A screen will help to bring out the bestin your projector and there are a range of fabric types that can even enhance what the projector is outputting. Projection screens have a special reflective coating that ensures that the light is evenly reflected back to you, rather than being absorbed, which can be the case when projecting straight onto a wall. So while you do not have to use a projector screen, we would strongly recommend it to ensure that you get the most from your projector! If you can’t use a projector screen, you can consider using screen paint - this will replicate the reflective surface of a projection screen on your wall.
