A screen can improve the viewing effect of a projector. In this guide, we will introduce how to hang a screen and share some tips about projector screens.
Some projector beginners just project the image on a white wall. Is it necessary to hang a screen?
There are many benefits to a projector with a screen. Here are the top three advantages.
1. Brightness Gain
The screen and white wall produce images because of light reflection. Even the cheapest screen’s surface has its own reflective coating, which receives the projected light without loss or even gains reflection and then produces a clear picture with rich contrast.
However, as the white wall is not pure and uneven, its light release rate and picture quality are not so good. It will be worse if the projector is not bright enough.
2. Black Bar Effect
Almost all screens have a circle of “black bar”, which helps to gather the attention of the human eye so that users have an immersive viewing experience, while white walls do not have this function. The black bar effect is similar to the “letterbox” effect widely seen in cinemas.
3. Good Color Reproduction
There are many types of projector screens available on the market, including glass fiber, glass beads, metal, and other materials. On the whole, these screens have a better color reproduction effect than a white wall.
In this section, we will explain the screen types based on the installation methods.

Before hanging the screen, you need to determine the distance and height first. You can use an erasable pen to mark different positions first before fixing the screen to avoid deviation.

Generally, the screen should be 80-100 cm away from the ground. You can determine the screen height based on the four principles below.
Principle 1
The projector’s lens should be pointed to the center of the screen.
Principle 2
The general setting is to make the center point of the screen equal to the sight line of the audience. That is to say, Projection Screen Center Height = Seated Sight Height. If the screen is set too low, then the projected light will be blocked by the people in front, if set too high, the audience will need to look up.
Principle 3
The height of the screen should be adjusted according to the setting method.
Principle 4
The fixed frame screen should be separated from the top 10-20cm or the lower edge of about 70cm from the ground. If it is a conference room, the screen’s black edge should be higher than the desktop to avoid blocking.
Besides, if you need to hang a screen in a tidy way, you can reserve a position for the screen when you are making a suspended ceiling.
