"We look forward to 4KUNIVERSE being enjoyed in TV households across North America in what promises to be a breakout year in 2018 for the SES Ultra HD solution, and we are very excited about our international growth starting with Swisscom in Switzerland."

Hi-End Cinema in the Home. / Re: SONY's new HT 4K Laser Projector VPL-VW760ES

Here is a 5000ES stack I just finished testing at my house last week with Ken Whitcomb. My screen is 17 feet wide, but due to the temporary placement, the largest image size I could do was 14 feet wide.  We had 107fL on my ST130 Perf (1.2 gain with perfs) screen.

I plan to finish the permanent install after Christmas so that we don't have a huge mess during the holidays. I have to remove 6 studs and install a header. Also have to move some electrical and a plumbing vent stack.

But here are some images from the test. Top and Bottom stack is the easiest as the lens are closest together, but side by side works as well. Doing at side by side stack is the only configuration that will work in my room.

Here are some pictures from testing. These were just taken hand-held with an iPhone X, so they aren't perfect. But wow what a difference the stack makes for HDR.

Hi Mayer, Hope you are well! Been a while since we spoke.

I spoke with the Sony engineering team. The "Projector Calibration Pro" software has the Stacking "Panel Alignment" feature. They have confirmed it works with all their 4K projectors. And not just current models either. Even the older 4K models.

In the News / Delta starts selling FE Series HD and 4K LED displays, pitch 1.26mm to 2.5mm
« Last post by DCI forum on Sat December 09, 2017, 07:57:46 AM »
Delta Electronics, known from its Vivitek Display brand and ODM/OEM work starts offering its new FE Series of pre-set size configurations of large format LED monitor solutions in Full-HD and UHD. The FE Series Fine Pitch Indoor LEDs, Delta says: "boasts superb image quality and uniformity, and offers a wide variety of tiles to fit all indoor project requirements. Rugged and robust, the LED wall solution is designed to excel in high ambient light environments, capturing audiences' attention and helping provide an unforgettable experience".

It also comes with an aluminum die-cast frame that allows for precise installation for perfect alignment. Each LED module attaches magnetically to the cabinet for ease of installation and (front)serviceability.

Commenting on the introduction of the FE Series, Holger Graeff, General Manager Delta Displays EMEA, said: "The FE Series will accelerate the uptake of LED Narrow Pixel Pitch thanks to the way we now standardize the configuration, installation and maintenance of our 16:9 LED video wall displays. Now, the power of LED technology can be offered easier and faster by any of our AV Partners for use in a wide range of environments, with the reassurance of Delta's know-how in video wall and control room applications for durable and long lasting solutions at low maintenance costs."

Suited to indoor signage as well as command and control environments, the FE Series offers a modern, sleekly designed large format monitor, offering 1.26, 1.58, 1.9 and 2.5mm pixel pitch, each calibrated to create smooth, consistent brightness and colour throughout the display area. Uniquely, Delta Display Solutions now offers the LED cabinets in pre-determined sizes ranging from 110" to 220" in Full HD, and 220" up to 440" in UHD resolution. The fine-pitch pixels choices and size configurations perfectly accommodate a wide range of viewing distances and applications. Each is in an exact 16.9 aspect ratio – so there is no need to reformat or resize images - which fits standard content supplied via a multitude of sources, as easily as if connecting to a monitor. The individual modules are 27" diagonal.

Delta says its FE Series of indoor LED Display Systems start from 75.000 EUR, excl. installation. Would that be for the smaller, but finer pitched 110" HD display or the 220" 2.5 mm version? Delta does not say. At this price it basically offers HD resolution Direct View LED where comparable LCD displays offer 4K resolution. An interesting price point reduction for LED. Of course the real cost is in the finer pitches and 4K.

LED curtains and higher pitched displays are commotized and can be had for low prices. In Europe one local signage company offered a LED curtain for 1500,- euro and up. But these often have a 20 mm pitch, and represent a completely different product from the fine pitched high end video displays.

The seamless and high resolution display provides wide-viewing angles giving an immersive experience that maximises audience engagement in short viewing distances. Delta's FE Series offers optional ambient light adjustment, emitting a bright and vibrant image no matter what the ambient factors are, such as bright, dark and variable lighting conditions. The FE Series' matched contact points between each tile provide superior accuracy and a seamlessly tight display, while ensuring a solid performance with excellent uniformity, colour and brightness over its lifetime.

The power supply developed by Delta and optimised for the FE Series supports the level of quality and durability that Delta stands for.

Delta lists the following Key Features:

·         Each individual cabinet has a 16:9 aspect ratio with a 27" diagonal
·         Full-HD configurations available in 110", 137", 165" and 220" diagonal
·         UHD configurations available in 220", 275", 330" and 440" diagonal
·         Cost-effective indoor SMD LED
·         A seamless and high-resolution display gives an immersive experience
·         Wide viewing angles allow for maximum audience engagement in short viewing distances
·        Minimal power consumption: Delta FE is designed with optimised power supplies to minimize power consumption, allowing for a low cost of ownership
·         Rugged and lightweight design guarantees reliability
·         Delta's uniformity calibration technology provides uniform colours and brightness
·         Front installation options and a compact, lightweight design guarantees an easy, quick installation
·         The ultimate indoor LED display for image quality assurance, colour uniformity and low cost of ownership
·         Certified UL, CB, CE, FCC, CCC

Here is a link to an old movie describing a tv setup with a Nipkow disc "flying spot scanner" @ 48 lines from GE Company in Schenectady 1931.

The Nipkow disc on the transmitter side projects the bright spot from a high power incandescent lamp house onto the subject. The reflected light is taken up by massive photo cells and this is what drives the receiver side. The machine is shown in all its details which makes for interesting viewing. -
You can also see the results of the machine filmed directly off the receiver. This gives a good idea of what these images looked like at the time.

The receiver uses a lens disc to project the image onto a screen. The light from an arc lamp passes thru a "light valve"- again a Kerr cell or something similar to it.

This obviously was a well engineered system.
