Reference Studio 4K Tab-Tensioned Motorized Screen Features

Durable Long Life and Upgradability

Our Reference Studio 4K Tab-Tensioned motorized screens have a very long expected life of 15-20 years, due to the use of our Pure Flat Tab-Tensioning system, which involves the use of a large asymmetrical roller tube, heavy weight bar, and precisely tensioned tabs at the sides of the screen. This long life, combined with our Reference Studio 4K 100EL 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.

Performance

The superb video performance of the Reference 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.

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.  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.

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 100 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 100 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 intact, while the other competitors severely degrade the pixel geometry despite being much more expensive than the EluneVision Reference Studio 4K family of screens.

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.

Pure-Flat Tab-Tension System

EluneVision Reference Studio 4K Tab-Tensioned motorized screens use our specially designed tensioning system known as Pure-Flat Tensioning system. The first stage of our Pure-Flat Tensioning system involves using an extremely heavy weight bar at the bottom. The bar is made of solid steel and its weight ensures that the screen is under great tension in the vertical direction, thus eliminating swaying from vibrations or moving air.

The second stage of the tensioning system involves the use of tensioned tabs at each side. This system allows tension to be applied horizontally, ensuring a flat surface. Our specially designed system ensures a smooth flat surface and prevents curling. Year after year, the screen will be flat and wave free.

Wrinkle Free Screen Spindle

As the fabric is rolled into the roller tube, where the fabric first meets the tube will cause a slight indentation that will repeat at regular intervals across the material. This problem is solved by using a symmetrical roller tube with a grove for where the material is first placed into. This ensures there are no repeating horizontal indentations in the material.

In order to bring you a flat picture, major design innovations had to be employed in the design and engineering of the screens:

1. The Reference Studio 4K 100EL fabric is slightly elastic and therefore works perfectly, as it can be tensioned to create a perfectly flat canvas for your movies.

2. An extremely heavy weight bar is used as the bottom bar. The bar is made of solid steel, to ensure that the screen is under great vertical tension and eliminates swaying from vibrations or air movement in the room.

3. The tensioning system involves the use of tensioned tabs at each side. This system allows tension to be applied horizontally ensuring a flat surface.

4. The tension of the screen can be adjusted using adjustment knobs located at the end of the bottom bar.

Tubular Heavy Duty Motor

EluneVision motorized screens use a combination of quiet and reliable tubular motor with self-adjusting bearings, The screen rolls down smoothly, as the motor features patented technology which removes vibration and increases smoothness.

For the video connoisseur who needs a motorized screen, the only choice would be a tensioned screen, as flatness is key to preserving the media as it was meant to be seen. A surface that is wrinkle-free and without any distortions is the ideal to which a movie will be projected. This is where the Pure-Flat Tab-Tension system really shines.

The screen material is rolled onto a large diameter roller tube, making the screen surface flatter, as there is less curvature in the material when it is rolled up, versus the smaller roller tubes commonly employed by most screen manufacturers.

Designed with Installation Versatility in Mind

EluneVision’s Reference Studio 4K Tab-Tensioned screens are designed to be hung from the wall, fixed to the ceiling or even hang from a chain.

Installation with Reference Studio 4K screens is easy and extremely fast. The screens come with a rail mounting system which means you have the freedom to place the mounts where you want. This greatly simplifies installation and shortens setup time. The mounting brackets support ceiling mounting, chain mounting and wall mounting. Furthermore, all our screens come with remote control, wall panel control and 110V power plug for plug and play operation.

Easy to Adjust Down Limit Controls

Clearly marked and easily accessible limit switch adjustment holes allow limit switch adjustments to be done in a snap. A special limit control tool is included with your screens to make this process as simple as possible.

Wireless Remote Offering Ease of Use

The Reference Studio 4K Tab-Tensioned motorized screens comes with a integrated control into the housing, 110V outlet plug and RF remote control. This ensures our screens can be operated under a variety of situations with the upmost ease. The integrated circuit board is hidden for in-ceiling and regular installations.

Universal Wireless Trigger (Optional)

Numerous screens come with the availability of 12V trigger port; however in many circumstances the conventional 12V wireless trigger may not be sufficient to satisfy all the needs. Introducing the high performance and versatile Universal Wireless Trigger, it is a specially designed wireless trigger for Reference Studio Tab-tensioned motorized screens. The Universal Wireless Trigger is connected by IEC C13 and C14 instead of 3.5mm trigger port, it triggers from the change of power usage through the connect line. Plug this unit between your projector and its power cord and the trigger will memorize the power difference the projector uses between ON and OFF, thus triggering the screen DOWN or UP. This feature is tested and proved reliable with various brands of projectors.
