Do you really need to buy a genuine and dedicated projector screen? Or can you view projected images on a simple bare wall? Well, you can use a blank wall as a projector screen, but it won’t be an ideal scenario at all!
You may try to prepare a wall to match a genuine screen’s smoothness and reflective properties. But in reality, the wall can’t match a screen in terms of uniformity, clarity, or right viewing angle of the projected images.
Especially it is true when you’ve got a high-definition video or image to show to a larger audience.
In this article, we don’t rule out the use of the wall as a projector screen; rather, we put light where the actual projector screen excels over a wall and also discuss how it’s backed by both technology and art.
Can you use a projector without a screen?
Yes, you can use a projector without a screen! But it’s not recommended because you can’t expect the best possible quality of the projected image without using a screen.
The projection screens are ultra-smooth and meant to reflect light best. So using a wall or anything instead of the screen won’t reflect enough light to create the clarity of the viewable images.
The screen is designed by professionals keeping in mind several factors like viewing angle, gain, polarization preservation, etc.
They make sure that a higher amount of projected light is delivered to the audience evenly over a narrow dispersion pattern.
On the other hand, the wall can’t be prepared like a screen surface and can have flaws or cracks, adversely affecting the picture quality.
Therefore, even if you can use a projector without a screen, this isn’t an ideal option to go with.
Can You Use a White Wall for a Projector?
Yes, you can use a white wall for a projector when you really can’t have a dedicated screen. Some even consider a white wall as the second-best option for projection.
The good thing is it reflects light better than walls with a different color. But to enjoy the best possible image quality, you’ve to smoothen it as much as possible by sanding and grinding. And then apply white projector paint.
You can also use a frame around the projection image to make it look like a projector screen.
Although it’s the easiest and cheapest DIY option for projection, there are some obvious downsides as well.
One of the major downsides is the wall’s rough texture, which can’t match the smoothness, hence the light reflection ability of a projection screen.
The walls still remain with fine bumps or cracks that you can’t see with the naked eyes. These flaws can harm the clarity of the images.
Is Projector Paint as Good as a Screen?
Projector paint makes a difference when it comes to making a surface more reflective, but it’s not as good as a screen.
While the paint increases the reflectivity, it can’t do anything to improve the ultimate smoothness of the surface or remove its fine imperfections.
But if you can sand or grind down the wall or surface you’re using the projector paint on, you could get better performance. But again, it can’t match the image quality of a good projector screen.
Does a Projector Screen Make a Difference?
Buying a good projector screen certainly makes a big difference in projecting clear and high-definition images.
An ideal projector screen will have a gain of 1 or more. It means the screen can reflect the light and color of the image uniformly over a 180-degree pattern of dispersion.
This type of screen is continuously developing to achieve a Lambertian surface (ideal matte surface) where the screen can provide Lambertian reflectance across the dispersion angle. As a result, you get a narrow viewing angle with more gain.
The special coating and ultra-smoothness of the screen enhance the reflectivity while also blocking incoming rays.
A projection screen makes a difference because you can’t have such smoothness and reflectivity in a wall or anything else. Although you can use a bare wall or a fence for a projector, you can’t experience such great clarity.
But the clarity and finesse matter when it comes to enjoying the movies, TV shows, or presentations with your fellow buddies.
Why shouldn’t I use a projector without a screen?
There are many reasons you shouldn’t be using a projector without a screen. The screen has its own advantages over other options, and some of these include:
So what Can I use for a Projector Screen?
There are a lot of projector screen alternatives available out there that you can use to project the image on. Some of these include smooth white bedsheets, wrapping paper, a big backdrop, blackout white cloth, and so on.
But nothing can match the picture quality of a genuine projector screen. If you’re planning to mount an actual screen, there are a few things you need to use for mounting your projector screen.
The most common mounting tool used for a projector screen is the universal hooks or screen mounting brackets that come compatible with most screens out there.
You can also create a shelf yourself that should allow it to sit on. Other mounting options include the projector screen stand, wall hangers, hanging strips, and so on.
Is Black or White Better for a Projector Screen?
When it comes to choosing between black vs white for a projector screen, white generally comes as an obvious winner. However, we’ve also seen a rise in popularity for black projector screens in recent times.
So which one’s better? Let’s find out!
White Projector Screen: Advantages and Disadvantages
The white screen is great for providing better reflection and brightness of the images. Also, it doesn’t distort images.
However, a white screen delivers the best results when there are no other light sources, and you’ve got a dark room to use the projector screen.
That’s why you see white as the default screen color in the video entertainment industry, movie theaters, or home videos.
But there are some downsides, especially when the room isn’t dark enough. It struggles with black levels, especially the deep black is hard to produce with a white projector screen. The high-contrast images are also hard to see on this type of screen.
Black Projector Screen: Advantages and Disadvantages
A black projector screen makes the best choice when there is ambient lighting in the room. It produces black portions of an image better than white screens. The high-contrast images also look better on this kind of screen.
Although bright images are more visible on a black screen, they could give a shimmer or rainbow effect sometimes. The black screen is also prone to hotspots which could result in uneven brightness of the picture.
You can avoid some of its disadvantages by using a grey screen which is a high-contrast screen but is less prone to hotspots.
Which Is Right For You?
Now time to take the decision, which one’s right for you — the projector screen or a bare wall.
Why Choose A Wall
Let’s first talk about the wall as a projector screen. If you’re planning for a cheap and easy projector screen option, then a wall could be a good choice.
You can easily prepare it by doing a bit of sanding, using special projection paint, and evenly laying a thin Lexan sheet over the wall.
Preparing a wall like this should give you a decent image quality when any multimedia content is projected on it.
However, we’ve said over and over again that it wouldn’t be able to maintain a higher amount of reflection, narrow viewing angle, or uniform brightness like what you’ll get in a genuine projector screen.
Why Choose A Projector Screen
Well, you’ve every reason to have a good projector screen as long as you can afford one. Luckily, a decent screen shouldn’t cost much as well.
By spending some bucks on a good genuine screen, you can have a great visual experience. Remember, projector screens reflect light and don’t emit it like TVs.
So it’s less straining to the eyes. It also helps you avoid hotspots while providing a better contrast ratio and clearer viewing angles. Most importantly, it keeps the uniformity and clarity of the images for a larger audience.
And that’s why you see all the multimedia rooms have a dedicated projector screen. Without such a screen, your content won’t be valued properly.
Besides all these, its customizable size and portability also add value to the product.
Figuring out between projector screen vs wall mostly depends on why you’re supposed to use it.
It’s possible that you don’t need a higher amount of clarity in the projected image. In such cases, you can use a blank wall as a projector screen by preparing it properly.
But if you’ve got a more sophisticated application where the picture clarity matters a lot, in that case, you shouldn’t think about anything other than a projector screen.
It is because only a well-made projector screen can bring the colors to live for you!
