Screens for laser and 4K projectors

What a 4K laser projector changes

A 4K projector displays an image of 3840 × 2160 pixels – four times as many as Full HD. On a screen 3 m wide, one pixel then measures about 0.8 mm. Such an image lets you sit closer and see more detail, but it also mercilessly reveals every imperfection in the screen.

A laser light source, meanwhile, usually delivers high brightness, and laser projectors for conference rooms are often rated at 4000–5600 lm. More brightness gives you more freedom in choosing the size and fabric, but also risks an over-bright image in a dark cinema room.

From the screen's point of view, four things matter: the texture and 4K compatibility of the fabric, the flatness of the surface, matching gain to brightness, and the right type of projector (standard or UST).

4K-ready fabric

The manufacturer of ADEO screens uses an embossed surface, which it describes as 4K Ultra HD-ready. In the 2025 fabric catalogue, every fabric is marked as 4K-compatible. The catalogue does not mention 8K, so do not assume compatibility without confirmation.

Pay particular attention to acoustic fabrics. The 0.5 mm perforation (Reference White 2 Acoustik, Vision Acoustik) is designed for typical home cinema and meeting room distances. The manufacturer aims the 1.3 mm perforation (Vision Macro Acoustik) at cinemas, theatres and very large venues where viewers sit far away. For 4K with close seating at home, choose the 0.5 mm perforation. Read more in our guide acoustically transparent screens.

Flatness – the key parameter for 4K

A roller screen without tensioning can show slight waves along the edges. With Full HD and presentations they often go unnoticed; with 4K and dark film scenes they become visible. The manufacturer uses features that reduce waves even on non-tensioned screens: a double-groove roller and two springs at the bottom bar. Complete flatness, however, comes from:

• fixed-frame screens – Plano, Prestige or Frameless, where the fabric is stretched over a frame,
• tensioned roller screens (Tensio) – e.g. the OnSuperior and InSuperior with Floating Tab tensioning, or the Rugby Plus in its Tensio Classic version.

How the different tensioning systems work is explained in our guide tensioned Tensio screens.

A laser projector in a conference room

Meeting and training rooms commonly use laser projectors of around 4000–5600 lm, usually in Full HD, with some models in WUXGA at a 16:10 ratio. A few tips on choosing the screen:

• Match the screen's aspect ratio to the projector – for WUXGA choose a 16:10 screen, for Full HD and 4K a 16:9 one. The image will then fill the whole fabric with no empty bands.
• Use the spare brightness – a 5000 lm projector on a 3.2 × 2.0 m screen with Vision White fabric (gain 1.2) gives about 300 cd/m². That is plenty even in a room with the lights on.
• Zoom and lens shift – projectors with around 1.6× zoom and vertical lens shift are easier to match to a screen that is already installed.
• Wide viewing angle – in a room with a wide table layout, choose fabrics with a 180° viewing angle so the image is even from the sides too.

Gain and laser projector brightness

A screen does not add light; it only distributes it. You can estimate image brightness (luminance) with the formula:

luminance [cd/m²] ≈ lumens × gain ÷ (π × image area in m²)

Example: a 16:9 screen 3 m wide is about 1.69 m high, with an area of about 5.06 m². For a 2500 lm projector:

In a darkened cinema room the reference point is often about 48 cd/m², so a powerful laser projector may produce an image noticeably brighter than needed. In that case a grey fabric with a lower gain, such as Reference Grey 2, helps improve black levels without sacrificing comfort. In a bright living room the spare brightness comes in handy and a white or ALR fabric makes more sense – just remember that a narrow-angle ALR fabric works best when viewers sit close to the screen axis. Detailed worked examples are in our guide screen gain and viewing angle.

Screen size and viewing distance at 4K

For home cinema the manufacturer gives this rule: image height equals the distance from the main seat divided by 2.5 (for Full HD and higher resolutions). 4K lets you sit closer – roughly 1–1.5 image widths away. Example: with the sofa 3.5 m from the screen, the manufacturer's rule gives a height of about 1.4 m, i.e. about 2.5 m wide in 16:9. With 4K you could consider a slightly larger screen, around 2.5–3.5 m wide. The full formulas are in our guide how to choose screen size.

Image size also depends on the projector's throw ratio: image width = throw distance ÷ throw ratio. A projector with a zoom range of, say, 1.38–2.21 at a distance of 4.5 m gives an image from about 2.0 to about 3.3 m wide. Lens shift lets you position the image without digital keystone correction, which reduces sharpness at 4K. We go through this step by step in our guide how to match a screen to a projector.

UST laser projectors (laser TV)

Ultra-short-throw projectors sit just below the screen and project light at a very steep angle. Any unevenness in the fabric then casts a clear shadow. For UST the manufacturer recommends a fixed-frame screen (Plano, Frameless, Prestige) or a tensioned roller screen, with Reference Grey 2 or Ambient Grey fabric. According to the manufacturer, Ambient Grey 2 is not suitable for UST. Read more in our guide screens for ultra-short-throw projectors.

What a screen cannot do

• Passive 3D – no ADEO surface is suitable for passive polarised 3D. If you plan to project 3D, check the projector's glasses technology before choosing a screen.
• Hot-spotting at high gain – directional fabrics can produce a brighter patch. The manufacturer describes Reference White 2 as free from hot-spotting.
• Reflections from light walls – a screen cannot make up for white walls and ceilings that scatter light and reduce contrast. A grey fabric helps, but dark room finishes are best.
