Long time no write. I know we only deal with projectors e.t.c but at this new place we might probably do an installation, the owner wants to put a video wall e.g. 360 degrees showing either from projectors or whatever. Anyone knows any good sites I can look about processors e.t.c regarding Video Walls? Video Wall Processors e.t.c. Thanks in advance and MERRY CHRISTMAS AND A HAPPY NEW YEAR 2004 (which hopefully will be the destructions of Digital Cinema) buahahahahaha  |  IP: Logged Ian Price Phenomenal Film Handler Posts: 1714 From: Denver, CO Registered: Jun 99 posted 12-30-2003 01:18 PM                     It's been years since I dealt with video walls. I'm sure all the processors I used are out of date now. They all worked very well and almost never failed. What did fail were the analogue CRT monitors. On average you get 3 good years out of a CRT monitor that is on 12-hours per day, then they start failing one right after another. After a fad in the 1990s where everybody had to have a video wall, now almost none are sold. They are too expensive and prone to failure and need constant professional adjustment. Most companies that want a video display use individual monitors, plasmas or for large images, an LCD or DLP projector in rear-projection mode. The reason video walls were popular was that at the time, that was the only way to display a large video image under ambient lighting conditions, now there are other options. That said, if you Google ‘Video Wall Processors’ you will get a lot of hits, happy reading. Let's see how long it takes for a moderator to slam this topic in to the Dark Side.  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 12-31-2003 12:20 AM                    I thought they were silly even back then.  |  IP: Logged Matt Hale Expert Film Handler Posts: 123 From: Vancouver, Canada Registered: Dec 2002 posted 12-31-2003 12:43 AM                        Christie makes such a unit: http://www.christiedigital.com/Products/products.asp?Port=3&ProdPartNo=38-FRC002 No experience with it personally but its a familiar name and if you're buying any of your film gear from them then maybe you can work it into the package? The only time I ever tried to build a video wall I took somewhat of a different approach. I took a Power Macintosh 9600 and outfitted it with 6 pci video cards - 3 singles and 3 duals for a total of 9 computer monitors. It worked but performance was far short of anything usable and that was top-of-the-line hardware at the time. You might get better results today, being that most any video card on the market will support 2 monitors. At the time they were very hard to find and very expensive. 14" monitors didnt amount to anything impressive but it could have done 9 20" screens just as easily (poorly.) Here is a (bad) picture of it lit up on my living room floor:  |  IP: Logged Jeffry L.

I did a sh*tload of those walls back in the 90's.... There are now much better, overall cheaper, and more cost-effective solutions to get the same effect. For example: A modern DLP projector driven by a multi-screen efx generator would allow the same screen effects as well as many other image options. The 9 or 16 or whatever the number of "displays" required for a "wall" are a real pain in the ass. Even with the great "cubes" like from Pioneer, they still require CONSTANT tweeking to maintain an acceptable overall image. IMHO: Lose the wall and get a "big" projector. Edit: Ooops! Not for a side-by-side, 360 degree layout.... For that you would need some sorta "wall" processor... >>> Phil  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

With new small DLP projectors it is less of a hernia to figure a replacement layout. Electrosonic and Imtech where some of the suppliers. During that period I installed a 35mm rear screen set up for trailers in one location and that unit is still running troublefree for nine years  |  IP: Logged
