Your canvas buying advice at visunext
In addition to the projector, the right projector screens are also crucial for a good projection. To achieve an optimal projection result, you should definitely use a projection screen, as it has better reflection properties than a white wall. We explain what you should look for in a projection screen and which projector screens are best suited for your application. Always make the right purchase decision with us !
Screen type: What types of screens are there?

The advantages and disadvantages of stationary screens
Screen type | Advantages | Disadvantages |
Roller screen | - Inexpensive - No cabling required - Easy to install - Permanent installation | - Manual pull-out by cord or pull-out rod - Exact positioning is comparatively uncomfortable - Usually only useful and available up to a width of 300 cm |
Motorised screen | - Electric motor instead of manual extension/retraction - Motorised drive protects the screen fabric - Convenient operation via remote control, trigger, etc. - Larger image widths and considerably more screen fabric selection | - Nearby power supply required - Higher installation costs depending on the room |
Recessed ceiling screen | - Almost invisible integration into the room image - Motorised drive protects the screen fabric - Convenient operation via remote control, trigger, etc - Larger image widths and considerably more screen fabric choice | - Suspended ceiling necessary - Must usually be installed by a specialist - Power connection required in the vicinity - Wider than classic motorised screens due to access panels |
Frame screen | - No ripples for perfect projection results every time - Enormously long service life - Suitable for all projection systems, especially UST projectors | - No invisible integration possible due to fixed installation - Permanently exposed to external factors such as sunlight or dust |
High contrast screen | - High colour contrasts even under residual light conditions - Hardly any darkening of the room necessary - Increases black level, in-picture contrast and plasticity of the image - In combination with a UST projector, an excellent TV replacement | - Comparatively high purchase price - Sensitive cloths due to the multi-layered plastic construction |

To ensure that the image is projected onto the screen in the correct orientation, the projectors always offer the option in the settings to be used for either floor or ceiling mounting. Depending on the projection mode selected, the projector automatically rotates the image so that it is always displayed the right way round.
The right canvas format and size
In addition to the screen format, the screen size is also decisive for a good projection. When determining the screen size, the distance of the audience to the screen as well as the distance of the projector to the screen must be taken into account in addition to the room size. To optimally determine the distance between projector and screen as well as the image size of the projection, our projection surface calculator will help you.
The ideal screen format must always be considered individually. Various factors play a role in the required screen size: Will the projector screen be used in a small home cinema or in a large auditorium?
Example: The ambient light on the projection surface is 300 lux. You want to project onto a 221 cm x 124 cm screen. The projection surface is therefore 2.74 square metres. This corresponds to a 100 inch screen in 16:9 format. The factor for bright room projection is 5. The following then applies: 250 lux 2.74 square metres x 5 = 3425. According to this formula, your projector should have a brightness of approx. 3,500 lumens for the location.
Please note that this is a guide value. To ensure perfect projection for your application, it is best to discuss your project with one of our visunext experts before making a purchase decision.
Modern projection surfaces such as high-contrast screens can increase the contrast of your projection by a lot. A special cloth structure increases the black level enormously, absorbs stray light and projects an excellent image even in bright rooms. You can find more information on the right projector for your projector screen in our projector buying guide!
The reflection behaviour of a screen is defined by the gain factor (luminance factor) depending on the viewing angle. The gain factor indicates how strongly the screen can focus the incident light. This bundling is decisive for the power and dynamics of colours and contrasts as well as for the presentation of a rich black level.
According to the international standard ISO 8396 and the German standard DIN 19045 Part 4, the reflection behaviour of canvases can be divided into the groups D, S, B and R. For approx. 90 % of all screens, manufacturers today work with types D and R. A type S screen roughly corresponds to a high-contrast screen. Type B screens are only used in isolated cases.
As a rule, type D screens are used. This type of screen is used in home cinemas as well as in conference rooms and classrooms. The other screen types are mostly used for special projection applications.
We are also happy to offer custom-made screens for your individual application on request.
