Daylight & Contrast Screens

Projection Screen Buying Guide 2026 - Contrast Screens

What makes a good picture?

A good picture consists of strong colours, crisp contrast and well-balanced brightness. These are exactly the aspects contrast screens are designed for: the aim is to match black level and brightness perfectly to create a picture with real depth.

In the age of HDR, this is something you simply won't want to do without!

How do I create the ideal projection environment?

The optimal projection environment is a completely darkened room – as many people know, bright walls and above all a white screen can make the picture look washed out, and such pictures are hard to enjoy.

In a bright room, ambient light reflects off the surrounding walls and brightens the projected picture. To avoid this effect, dedicated home cinema rooms are fitted with dark walls to optimise light concentration and improve the black level. But since many people have their screen in the living room – and are very unlikely to paint it dark just to hang up a screen – contrast screens were developed!

With a contrast screen, you can save yourself all that effort!

As contrast screens have dark screen fabrics, they block ambient light and mainly reflect the projected picture. Of course, optimal room darkening is still a little better – but a contrast screen comes very close.

In the following comparison, we have simulated the view side by side to make the topic easier to understand.

What is a contrast screen?

Contrast screens come in different strengths – high contrast or low contrast, with a high gain value or a low gain value. This luminance factor indicates how strongly light is picked up and reflected by the screen.

That all sounds very theoretical, so you'll find further information, a precise definition of this value and more about contrast enhancement in screens here.

How does a contrast screen work?

First, the most important rule of thumb about contrast: "A screen can only be as black as the room around it, because it is white itself!"

So far, so clear: a white screen will never show you the same black levels as a grey screen, which already has a darker tone of its own.

With a classic white screen, the fabric partly swallows the colour information, resulting in a brightened picture.
A contrast grey screen, on the other hand, is already tinted darker, so fewer colours are lost on the screen. The screen reproduces darker tones darker. The resulting disadvantage is also its advantage: dark colours become darker, but bright colours are also slightly dimmed – white light will never appear completely white on a grey screen!

In summary

• Matte white screens are not suitable for daylight
• Matte white screens are brightened by ambient light
• Contrast screens or gain screens increase contrast
• Thanks to their dark screen colour, contrast screens or gain screens prevent brightening by ambient light

What are the differences?

In general, we can distinguish between four different screen fabrics, all of which are contrast fabrics, but with different requirements, strengths and weaknesses.

Low-gain fabrics

These screen fabrics have a gain value well below 1 and darken the picture compared with the projector's native brightness (e.g. a projector with 1,000 lumens will only show approx. 600 lumens on a screen with 0.6 gain – and depending on the viewing angle, this can drop by a further 10% or so).

At first, this doesn't sound particularly positive, but the light reduction also produces less stray light, which optimises the black level and significantly improves the screen's contrast properties.
The resulting effect can be seen on the left-hand side of the image.

High-gain fabrics

With these screen fabrics, the overall gain value is well above 1, e.g. 1.5. These screens increase the actual brightness of the projector – in this case by around 50%. The picture becomes more radiant and generally brighter. This effect keeps contrast crisp and the black level strong, but the bright areas of the picture are also noticeably brightened.
You can see the resulting effect on the right-hand side of the image.

High-contrast fabrics

Unfortunately, these fabrics can't be defined by a clear gain value, but rather by the colour of the screen. With these fabrics, one thing is certain: the darker the fabric, the greater the increase in contrast.
The contrast boost is achieved because the fabric is tinted a very dark grey; combined with a low gain value, this creates a particularly high-contrast, dark picture.

In normal living spaces, such a fabric can produce a picture as good as in an optimised home cinema room.

The downside of these fabrics is a narrower viewing angle and more noticeable sparkle, as you can see in the lights on the left-hand side of the image.

Neutral-gain fabrics

These fabrics have a gain value of around 1 and therefore rely on the natural reproduction of the original image. No artificial brightening, no boosted contrast or anything similar – just the picture as the projector is meant to deliver it. The screen thus optimises the black level solely by filtering stray light, as you can see on the right-hand side of the adjacent image.

Which projector for your screen?

Of course, the screen is not the only deciding factor – that much is certain. The question of which projector is right for your screen is extremely difficult to answer in general terms.

What matters:

For ideal projection, the projector must be perfectly matched to the screen – because without the right projector, even the best screen is just a wall to project onto!

We're happy to give you a few pointers, and if you have further questions, take a look at our screen guide or our projectors category. And of course our experienced specialist advisers are always on hand to help.

Low-gain fabric combined with a projector

• Reduces overall brightness → bright projector required
• A moderate black level can be improved by the screen

On the right-hand side of the image, you can see the picture a bright projector with a moderate black level can produce.

High-gain fabric with a projector

• Ideal for less powerful projectors to brighten the picture
• Projectors that are too bright degrade the picture, especially in dark scenes

On the right-hand side of the image, you can see how a less powerful projector can look on a high-gain screen.

Neutral-gain fabric with a projector

• The picture is reproduced exactly as the projector outputs it and is only slightly optimised
• The higher the native resolution, the more the screen's qualities come to the fore

You can see the effect on the left-hand side of the image; it results from capturing the stray light of the picture to optimise it.

What are CLR and ALR?

These two terms describe technologies that prevent ambient light from being picked up by the screen.

• CLR – Ceiling Light Rejecting
• ALR – Ambient Light Rejecting

CLR refers to ambient light coming from above – literally, "ceiling light".

ALR refers to general ambient light that can enter through windows or from other light sources.

A screen with CLR or ALR properties therefore ensures that the picture is not affected by distracting ambient light.

As with all screens, other factors also play a role here – you'll find more information in our screen guide.
