Reference Studio 4K Fixed-Frame Screen Features

Performance

The superb video performance of the Reference Studio 4K series screen comes from EluneVIsion’s R&D efforts in creating a material that is 100% transparent to the user, and designed for maximum detail clarity when used with 1080p and 4K projectors. The material is a near perfect lambertian diffuser, which means that the light is dispersed evenly in a hemispherical distribution, allowing for a balanced and smooth light reflection. The smooth and even light reflection means that there is no hot spotting and or texturing. Furthermore, the material provides a near perfect white field uniformity and an extremely large viewing cone.

Durable Long Life and Upgradability

Our Reference Studio 4K Fixed-Frame screens have a very long expected life. This long life, combined with our Reference Studio 4K 100 material that performs at the studio/reference level, ensures that this screen can be used for many iterations of projector upgrades.

The projector technology today is advancing by leaps and bounds, which means that every 3-4 years is the optimum time to upgrade your projector. Because our screens perform at the highest level, you will be able to enjoy each improvement in performance to the fullest level on the Reference Studio 4K screens. All but the most expensive competitors are currently unable to fully support a 1080p image, which means by purchasing a non-Reference screen, you are effectively wasting the performance of your 1080p projector.

Due to our texturless surface and lambertian design, even when the resolution eventually increases to 4K pixel resolution, each pixel will be rendered accurately. Our competitors’ non-Reference class screens effectively down-sample today’s high-resolution 1080p projector to a lower-resolution image (as you will see in the tests/demonstration images below), and they will do it even more for tomorrow’s higher resolution 4K projectors. Whether you are purchasing a screen to get the most performance out of your projector today, or you are purchasing a screen that will work with video resolutions of tomorrow – the Reference Studio 4K series is the  best solution.

Reference 2D and 3D Performance

The Reference Studio 4K series of screens is designed to maximize detail, resolution and uniformity for both 2D and 3D projection. To get the best 3D immersive experience, the screen must be free from artifacts, hot spots and textures. Any flaw in the material and in the reproduction will contribute to a loss of immersion and viewer fatigue due to increased cross talk.

Texture-Free Screen Surface

At EluneVision, much effort was spent designing a projection material that is texture-free. The result is the Reference Studio 4K 100 family of materials have an extremely smooth and pit free surface. The EluneVision Reference Studio 4K family of screens have the highest clarity, sharpness and definition of any projection screen released to date. This means, simply, that the geometry of each projected pixel remains as the projector manufacturer intended.

To illustrate this point, see the screen material texture comparison below, showing our Reference Studio 4K 100 material beside Stewart’s (widely considered the gold standard, but at a much higher cost), as well as two other more expensive competitors.

From the above demonstration, it is clear that the EluneVision Reference Studio 4K 100 material is rivaled only by materials multiple times higher in price, and is by far better than materials even 50% higher in price.  How does this texture-less material convert to real-world performance? Let’s find out.

Perfect Pixel Geometry

The lack of texture leaves pixel geometry perfectly intact with our material. Why is this important? With 1080p projectors now standard, EluneVision’s Reference Studio 4K material ensures that the effective resolution remains at 1080p, while other (more expensive) competitors degrade the pixel geometry to the point that the effective resolution is no longer even close to 1080p. Also due to the fact that there is zero texturing and perfect preservation of detail clarity, the Reference Studio 4K material will perfectly resolve 4K resolution in both today’s high end and future 4K projectors, saving you a screen upgrade.

To illustrate this point, see the images below, showing our Reference Studio 4K 100 material beside Stewart’s (widely considered the gold standard, but a much higher cost), as well as two other more expensive competitors.

The test above clearly shows that our material, as well as the much higher priced Stewart Studiotek 100, keeps the pixels in tact, while the other competitors severely degrade the pixel geometry despite being much more expensive than the EluneVision Reference Studio 4K Fixed-Frame screen.

No Sparkles or Graininess – Complete Invisibility of Screen Material

Due to the use of a smooth and near perfect Lambertian diffuser material, our screen has absolutely no sparkles. The material was purposely engineered to disperse the light evenly in a hemispherical distribution, creating a perfect reproduction, as the director intended. The Reference Studio 4K 100 material will easily pass any of the common sparkle tests, which include fast action bright scenes in movies as well as hockey, football, and other sports. This means that viewer will always see the image displayed on the screen as the projector manufacturer intended, and will never see the annoying imperfections present on competitors’ screen materials.

Moire Free With All Projection Technologies

When an image’s pixel pattern does not match that of the textured surface it is displayed on, moire is created. The mismatch causes a wavy, non-uniform, interference pattern which degrades projected image quality and uniformity.

The Reference Studio 4K 100 material completely eliminates this problem because the screen material is 100% texture free, which means that there is no textured surface pattern that could cause the creation of the interference patterns. Furthermore, the Reference Studio 4K 100 material has been tested with LCD, DLP, D-ILA and SXRD projectors to ensure a moire-free picture at various throw distances and viewing angles.

To the left is an example of how moire can impact picture quality.  When you zoom in, you see that the competitor’s screen creates moire on the woman’s dress, causing artifacts patterns that are not supposed to be on the image.  Furthermore, the moire pattern also causes discoloration, as green hues are introduced on what is supposed to be a completely blue dress in the competitor’s image.

Near-Perfect Lambertian Diffuser Viewing Surface

At EluneVision, we believe the perfect screen is one where you never notice the screen surface under any conditions. In many poorly designed projection materials, the screen texture and surface will become visible to the viewer, taking away from what is being projected. In order to design a material that can be called Reference, we engineered a material that is a near perfect Lambertian diffuser.

The surface of a material exhibits Lambertian reflectance if the viewer sees the same image or brightness regardless of the viewer’s angle. From a more technical perspective, this means the incident light is scattered in all directions equally. A good example of this is an unfinished block of wood, where no matter what angle you view it, the luminance is roughly equal. In contrast, finished wood with a glossy coat of polyurethane exhibits specular highlights, which are areas of brighter luminance when viewing at different angles. While this glossy finish may be beneficial on furniture, it is the cause of numerous problems in projection screens.

Absolutely No Hot Spotting – 100% Screen Transparency

A big problem that you see with all but the best screens is an issue known as hot spotting. Hot spotting results in an area at the center of the screen with high glare and light, surrounded by a comparably darker image at the top, bottom and sides of the screen. As seen below, this results in a very unnatural image. This is not a phenomenon that only cheaper screens suffer from – there are countless examples of significantly more expensive Reference Studio screens from competitors that suffer greatly from hot spotting, serving as a testament to EluneVision’s engineering efforts in perfecting the Reference Studio 4K 100 material quality.

Reference Studio 4K 100 material provides perfect white field uniformity due to the material’s Lambertian diffuser nature. The brightness will be even across the entire screen and there will not be areas of the screen which are brighter or dark to the viewer at any viewing angle. When projecting a pure white scene, the white level will be even from edge to edge, with absolutely no hot-spotting or texturing , demonstrating a reference level of performance and image quality.

Colour Neutrality and Accuracy

EluneVision’s new Reference Studio 4K 100 material is designed specifically to achieve the highest level of color reproduction. To achieve this, the material is designed for a completely neutral color reproduction. The Lambertian diffuser property, in addition to a specially designed white base color, maintains color accuracy across the entire color gamut. Many other projection materials in the market today will exhibit a shift in hue, either to the blue, green or red. This creates an unnatural balance to the colors and will decrease the color uniformity and vibrancy.

Above, we see a demonstration of this phenomenon.  The top zoom-in shows the competitor’s screen versus our EluneVision Reference Studio 4K 100 screen material. Note the color shifts that the competitor exhibits, as well as the minimization color shifts of the EluneVision Reference Studio 4K 100 material.  This results in the color accuracy of the whites and the reds you see in the EluneVision Reference Studio 4K 100 screen material image.

Ultra Wide Viewing Angle

Due to the near perfect Lambertian diffuser properties of the Reference Studio 4K 100 material, the viewing angle is a full 180 degrees, allowing seats to be placed off axis without any changes in brightness or white field uniformity. The image on the Reference Studio 4K 100 material is consistent from edge-to-edge at all viewing angles.

To demonstrate this, photos were taken and posted below (the images were not re-touched).  The first one shows a projected movie in a front view, while the second shows the movie at a fairly extreme side view. Though the user would not normally sit this far off center, the photos below demonstrate the fact that in any way that you decide to arrange seating, the screen will perform with perfection from any viewpoint.  This performance extends to the height and location that you decide to mount the projector. Whether ceiling mounted and centered to the screen, or table mounted too far to the left/right of the screen, the image the screen projects back to the viewer will not degrade.

Seamless Video Reproduction with Contrast Enhancing Sound Transparent Black Backing

The black backing is one of the most important aspects of an acoustic weave fixed frame screen. All acoustic weave screens will leak a bit of light due to the perforations in the screen. This light can then hit the surfaces behind the screen and bounce back into the material and thus lowering black levels.

To combat this problem, a specially designed, highly porous and low-density black backing is used to absorb the light leakage and provide better black levels. Not only does this enhance video performance, but as demonstrated above in the audio section, it will not negatively impact the audio performance of your home theater setup.

Engineered for Active 3D and 2D with 1.15 Gain

With a gain of 1.15, one of the highest gains for acoustic weave materials; the Reference Studio AudioWeave 4K NanoEdge delivers high contrast images without any of the drawbacks of high gain screens such as hot spotting, texturing and graininess. The higher gain helps with brightness of the projected image and counters the loss of brightness due to active 3D shutter glasses.

Near-Perfect Lambertian Diffuser Viewing Surface

The thread used to weave the Reference Studio AudioWeave 4K material is chosen for its Near-Perfect Lambertian Diffusing properties. The end result is that you get a screen that is has a full 180 degree viewing angle and does not suffer from the effects of hot spotting, graininess, or texturing. The screen under proper usage conditions (viewing distance greater than 8 feet) will remain a near perfect canvas for the projector.

The surface of a material exhibits lambertian reflectance if the viewer sees the same image or brightness regardless of the viewer’s angle. From a more technical perspective, this means the incident light is scattered in all directions equally. A good example of this is an unfinished block of wood, where no matter what angle you view it, the luminance is roughly equal. In contrast, finished wood with a glossy coat of polyurethane exhibits specular highlights, which are areas of brighter luminance when viewing at different angles. While this glossy finish may be beneficial on furniture, it is the cause of numerous problems in projection screens.

Perfectly Flat Screen Surface

EluneVision Reference Studio 4K Screens use an easy to install snap on pre-calibrated anchor tensioning system. Each side of the frame has 5 to 20 anchors, providing a perfectly flat viewing surface. The screens use a two-stage tensioning system. The first stage is composed of a frame tensioning system, where anchors are placed at factory calibrated locations along the frame rail to provide the flattest possible screen surface. The Reference Studio 4K series uses no fewer than 20 anchor points to fix the screen material to the frame.

The second stage uses force equalization rods, which are inserted into the perimeter of the material to distribute the tension force evenly across all anchor points. The rods ensure that there is no sagging, creases or V waves in the material. The Reference Studio 4K two-stage tensioning system means that the screen will be completely flat, and will remain so year after year.

Solid and Luxurious Construction

Plush 4” Velour Wrapped Aluminum Frames

At EluneVision, we know that most manufacturers are producing expensive screens with 3” aluminum frames as standard. However, we were never satisfied with matching our competition – we wanted to bring a product that not only has superior performance but also bring a new level of luxury to any home theatre or studio.

The Reference Studio 4K series 4” thick velour frames raises the standard of which all fixed frames are compared to, and bring a new level of luxury to any home theater or studio.

High-Density Velour Pure Black Finish

During the engineering and design process of the Reference Studio 4K series screens, we decided that we wanted to improve upon the already excellent velvet frames of the Elara series. The specifications we set forth was to increase light absorption, as well as overall fit and finish. After researching different possible ways to accomplish these two objectives, we found the answer. By using a high-density velour material, we achieved an increase of 40%+ in light absorption and managed to achieve a high end, plush and luxurious finish.

Look at the photo on the left, where a more expensive competitor’s frame was placed beside ours in a highly light-flooded room – the EluneVision Reference Studio 4K screen absorbed all the light, while the competitor’s screen struggled.

Forged Aircraft-Grade Aluminum Construction

The entire frame on the Reference Studio 4K screens is made from forged aircraft-grade aluminum. The all aluminum construction, in combination with the 5” width, means that the screen will not bend or bow under any circumstances. The frames are forged as a single piece and therefore do not have any weak points where it may break or deform under strain.

The 45 degree edges of the frames are cut using an industrial high precision CNC laser cutter, ensuring only the highest precision cuts. This means that the corners line up perfectly, creating a seamless frame with no visible joins at the corners.

Easy Installation

Installing the screen is a snap, literally. With our snap on tension system, your screen will be ready for primetime within 1-2 hours. Our screens also come with movable mounting brackets which allow greater versatility of where to place the mounting screws. With a few simple tools you’ll be watching all your favorite movies and sports in no time.
