Screen Test

Advent Media has an 80" Supernova Mobile to use for PainFree Presetations™ work, and so we did some quick comparisons between it and a standard Matte White screen. A single 3000 lumen LCD Projector is displaying both images, meaning the light output is on the order of a 1500 lumen projector for an equivalent image size. Three 50 watt floodlights are illuminating the screen from about 3' in front of it, and the rest of the room lights are on full. This simulates lighting that might be found in a LEED - certified building.

Scroll on down to see actual photos of the Supernova Screen in use at a trade show.

Here's our first graphic. This is a typical PowerPoint slide that I duplicated so identical images would display side by side.
As a control this shows the two images on the Matte White screen, illuminated by 3 50 watt floodlights 1' above and about 3' away from the screen. This slide conforms to PainFree Presentations principles, so all text is readable even in this situation, but the glare from the illuminated screen is irritating.
Raising the SNS screen, blacks look black! Shadow detail is apparent. The colors pop.
Here's our second graphic, a typical blue background PowerPoint slide with a somewhat difficult photo. The slide conforms to PainFree Presentations standards for high ambient lighting.
And here's it is side by side on the Supernova. While you can read the text on the Matte White because of the formatting, you can't see shadow detail in the photo. But on the Supernova, everything is there, colors are rich and shadows are dark.
This is a nice picture of a stand of trees. I chose it because of its shadow detail in the grass and the texture of the foilage.
And here is that image unretouched on the SNS. You can see the shadows.
This is a worst-case scenario photo. It's all very dark and somewhat underexposed. Normally you'd need all the lights off to project something like this.
The camera does not do this justice, but you can actually see detail on the SNS! (The color shifted blue because the camera's white balanced locked onto the incandescent light - it looks a lot better in person.)

Bottom line?

The dnp Supernova Screen™ works as advertised! Call 614-538-1622 for an on-site demonstration (in the Columbus area). Or drop us a line by clicking here. You have to see it to believe it!

Just to let you know, these are serious screens for serious presenters! The 80" portable screen (pictured) sells for $3,500. But if you need to project in brightly lit rooms, this screen can save the show.

Surface Comparison

The Supernova One Screen and Core screens have two surface options. The "20-20" screen is a high brightness screen, reflecting twice the light (2.0) as Matte White (1.0). However the super-bright reflectivity is within a 20-degree viewing angle of the lens, offering about a 40-degree viewing cone. Wider than that, the brightness falls off a bit, though it remains viewable.

The "08-85" surface has a reflicivity of .8, slightly less than matte white (1.0). However this surface has an 85-degree viewing angle, offering almost 180-degree viewing cone. (Any wider and you can't make out the image anyway.) No other "gray" screen boasts this wide a viewing angle. Even in a wide seating situation, everyone can see clearly.

To show you the differences, here are two more "screen tests" utilizing Supernova One demo screens:

This is our test image. Notice the red berries, dark background and detail on the leaves. Other than resizing, the following images are unretouched.

In this image, the berry image is projected across the Supernova One sample screens, in front of the DaLite matte white screen. Note how washed out the image is with the 3 50-watt lights shining directly on the screen. On the left is the 20:20 surface, showing it's 2.0 gain (twice as much reflectivity as the matte white.) On the right is the 08-85 surface. You can see how it is a little darker. In this light, a brighter projector would be helpful. However...
This image is about 45-degrees to the side. Notice how the 20-20 image brightness has fallen to about that of the 08-85. This means that if you have a narrow room with high light levels, the 20-20 will give you a brighter image, but if you have a wide audience, the 08-85 with a brighter projector will be preferable. With either screen, the image is dramatically improved with Supernova.

IN THE FIELD

The October 2009 Green Industry Expo featured our Supernova Screen at the Professional Landcare Network (PLANET) booth, displaying the Team PLANET video we created along with the winners of the 40th Annual Environmental Improvement Awards. The picture quality from the 3000 lumen XGA projector on the 80" Supernova Screen was stunning, as these unretouched pictures show:
