Diamonds Are a Light's Best Friend
I am installing a new home theater, starting with a Panasonic PT-AE4000U projector, and I wonder about which screen to use. I would like a 16:9 or 2.35:1 screen. The room has some ambient light, but it can be made totally dark. What do you think of the Screen Innovations Black Diamond II? I have seen some YouTube videos about it, and it really looks great, but I wonder if it's worth the high price?

Norwegian manufacturer projectiondesign has announced a new line of projectors under the avielo moniker. Based on Philips' VIDI lamp technology, which increases brightness and contrast by producing alternating bright and dark pulses in the lamp, the avielo line launches with five models ranging in price from $7500 for the 720p Prisma to $65,000 or $70,000 for the dual-lamp 1080p Helios pictured here. All are shipping now except the Helios, which should appear by the end of the year.

At the CEDIA Expo next week, Norwegian Projectiondesign will introduce three new DLP projectors branded with its Avielo moniker. Here's a preview...

The demo of Projectiondesign's 3-chip DLP Helios was mighty impressive on a 2.35:1, 11-foot-wide Da-Lite Affinity screen. The clip was from <I>10,000 B.C.</I>, an eminently forgettable movie that was chosen because it was color-graded on a Projectiondesign projector. The dual-lamp Helios was at its minimum lamp and iris settings to accommodate the screen, which means it can easily fill a screen up to 16 feet wide. Like the Kroma, the Helios produced very natural skin tones and razor-sharp detail.

Among the many LED-illuminated front projectors expected at CEDIA is the Kroma from Projectiondesign. A preliminary spec sheet for this single-chip DLP design claims a peak light output of about 600 lumens, a contrast ratio of up to 7500:1, and a lifespan of over 50,000 hours. Also, there's no need for a color wheel since the red, green, and blue LEDs are activated sequentially, and much faster than any color wheel's filters can move in and out of position, which means fewer&#151;if any&#151;so-called "rainbow artifacts." Pricing and availability were not disclosed prior to the show.

I blogged about this LED-illuminated DLP projector before the show, but now I've seen a demo, which looked great on a Da-Lite Affinity screen (0.95 gain), even with some ambient light. The LEDs are claimed to have a 100,000-hour lifespan, which corresponds to 12 or 13 years of normal use. Colors looked quite natural thanks to the advanced calibration process that assures an accurate color gamut and grayscale.

Projectiondesign's press conference concentrated on the Optix SuperWide 235 (around $39,000 with a standard lens), whose DLP imaging chip boasts a native resolution of 2560x1600, though this model uses only 1080 horizontal lines. This projector can display any aspect ratio from 1.33:1 to 2.40:1 at constant height without needing an anamorphic lens or zoom memories, which rob the image of brightness. For wide-screen Blu-rays, it scales the image vertically and horizontally using Sigma Designs VXP processing and two custom FPGA (field-programmable gate array) chips to fill the 2560x1080 pixel structure and maintain a 12-bit color depth per channel.

The demo was shown on a 13-foot-wide Da-Lite Affinity screen (1.1 gain) with a hand-built prototype with only one of two lamps in operation, so we were seeing a peak-level of about 7.5 foot-lamberts. Clips from Paul Blart: Mall Cop and Spider-Man 3 looked quite good, though I would not have chosen Paul Blart—what an awful movie!

I hadn't heard of the Quantum before the show. This is Projectiondesign's "entry level" projector, which should be shipping next month for roughly $11,750, depending on the selected lens. It's small but mighty with a 220W UHP lamp and high-quality optics.

I have designed and framed out a dedicated home theater with a separate room for a projector to project the image onto a translucent screen to be viewed in the theater room. I spoke with both projector and screen manufacturers before construction, and I asked them which would produce a better image—traditional front projection or rear projection such as I have in mind. The answer was unanimous: rear projection would produce a better image. I realize that the market for this type of setup is much smaller than traditional front-projection because of the obvious design considerations. But there are many advantages over front-projection, primarily and most importantly a better picture as well as no projector noise or heat in the viewing area. I would love to see some discussion on this type of projection in the magazine.

Do you have any idea why the colors of an InFocus projector have turned green-blue (or rather lost red) after only 250 hours? Is this an indication of lamp aging?
