Is a 4K projector screen that different from a standard screen?
Simply put – Yes! This difference is all about texture and how this impacts on the quality of the final image.
When viewed under a microscope (see image), a standard matte white, non-tensioned projection screen surface has imperfections in the physical structure. You can see in the image the tangible texture to this surface.
This texture means that pixel clarity is lost, which creates visual “noise” and an overall softening of the image. Texture means the surface can’t perfectly reflect the projected image.
On lower resolution projectors the improvement offered by a projector screen in comparison a blank wall is sufficient to get a great quality image from the projector and do justice to the device’s capabilities in terms of resolution. But with 4K content producing four times the detail of 1080p Full HD, pixel preservation becomes much more important to the fidelity and clarity of colour in your image, when you’ve invested in a 4K projector.
This is where (and why!) 4K UHD projector screens are different.
As standard, the 4K UHD vinyl material on the screens we sell are tensioned and have a 0.9 gain which is suitable for low ambient room lighting conditions only. We can provide other screen gains on request. The material creates a totally smooth surface, free of microscopic dips or grooves, and allows the screen to disappear and the image itself pop! The result is the best surface for your HD, 4K and Ultra HD projector, allowing you to get the very best out of your investment.
Why a tensioned screen surface offers the best image reproduction
A flat projection surface gets you the most out of your projector, and makes sure no pixels end up lost or deformed. If detail and pixel preservation is important, a perfectly flat projection area is vital.
Non-tensioned projection surfaces can have waves or ripples, which create shadows and deform the projected image. A tensioned screen, on the other hand, is tensioned both vertically and horizontally, creating a perfectly flat projection surface.
The material we use also impacts on the ultimate tension. Temperature and humidity can have a negative effect of the flatness of the surface, causing it to sag down over time, and again deforming the final projected image. A tensioned vinyl screen is much better equipped to withstand changes in temperature and humidity, giving you a crisper image for longer.
Fixed Frame 4K Projector Screens
Fixed frame projector screens are a permanent fixture in the projection set up. Black velvet borders provide the eye with a focus point. They also eliminate reflection and absorb stray projected light.
The 4K UHD screen material is formulated to provide a screen surface free from microscopic variations preventing pixel loss and noise, meaning that the screen essentially disappears from view, leaving you to focus on what matters: the image.
Like all of our 4K UHD projector screens, our fixed frame screens are tensioned to keep the projection surface under a constant tensioning for a perfectly flat viewing area.
If you can afford to dedicate permanent wall space to your projector then fixed frame projector screens are an excellent choice. You’ll see every last pixel of detail in crisp clarity, ensuring you get the best image from your device.
Electric 4K Projector Screens
If you need the wall space back when the projector is not in use but a ceiling-recessed installation is not feasible, then a wall-mounted electric 4K UHD projector screen is ideal.
Our recommended wall-mounted screen is the Projecta Tensioned Elpro Concept, which offers a high-end stylish solution for design-sensitive installations, without compromising on performance.
Like all of our 4K UHD projector screens, the Projecta electric wall-mounted screens are tab-tensioned to ensure you have a perfectly flat viewing area.
This screen itself is made with HD Progressive screen material to ensure the smoothest surface possible and a small electric motor is installed to conveniently hide the screen when it’s not in use. There is a huge amount of customisable size options, the potential to remove the black borders if you wish and even the option to paint the case in any standard RAL colour of your choice, and you’ve got one of the best 4K UHD projector screens on the market.
Electric Ceiling Recessed 4K Projector Screens
If your space allows it, an electric ceiling-recessed projector screen is the ultimate choice for a stylish finish in a non-permanent cinema room.
These projector screens are practically invisible after installation, winding back up into a space in your ceiling, but offering the best quality flat surface when in use.
Projectorpoint recommends the Projecta Tensioned Descender Electrol. On a practical level, installation is straightforward and the motor and screen surface remain conveniently accessible for maintenance if required at a later date.
As for performance, like its wall-mounted sister, the Descender Electrol uses a tab tensioning system to keep the projection surface under a constant level of tension, thus ensuring you get the smoothest possible surface.
HD Progressive screen material again ensures the best material for the job, offering image uniformity, pixel preservation, and colour fidelity.
These bespoke 4K projector screens offer numerous customisable features and can be made exactly to fit your space. Get in touch today if you’d like to find out more.
