When you go to a museum or large display  you can sometimes see where
they have put up 30 or so TV screens in a rectangle. (Say, five across
and six high).
They then take a signal and make each TV have 1/30th of the picture.
So, when all is said and done you get a giant picture created out of
30 tv's.
1. What is the hardware used to do this called?
2. Where to obtain, Ebay?

I have three questions:

1. Is this the kind of thing you have in mind?

2. When you say "TV screens," do you mean that you need to do this
with regular, garden-variety televisions, rather than video monitors?

3. Approximately what is your budget?

1. Yes, that is what I have in mind.
2. Either video monitors or TV's.
3. Answer kind of goes with answer 2. Basically, I saw these 20 years
ago at a museum. I figured that by now the electronics to run it would
be the size of a computer and be fairly cheap.
If I am incorrect then so be it. Basically, I wanted what the heck you
call the device that runs the whole thing. Might get lucky and find
one on ebay for cheap. I just want to know what to search for on ebay.
Heck, if my Mom can get a bottle of perfume on Ebay that has not been
made since she was a kid then I ought to be able to find these stupid
things.

It is amazing what you can find on eBay. How about this?

Let's call it good.
Wow, record time.
Worth every penny of $8

Thanks, answer it and close it.

The kind of multi-monitor display that you have described is often
called a "Video Wall" or "Display Wall." I have also seen it called a
"Video Matrix," but that term has other meanings, and is less useful
as a search term.

I've gathered a few online resources that I hope will be of interest:

Note that time is running out on the eBay auction:

Google search strategy:

Google Web Search: "create OR creating OR build OR building a video wall"
://www.google.com/search?hl=en&ie=UTF-8&q=%22create+OR+creating+OR+build+OR+building+a+video+wall%22

Google Web Search: "create OR creating OR build OR building a display wall"

I'm very glad to have been able to help. You hold a special status in
my career, since you were my first Google Answers customer, in August

I had meant to include one additional search string, for the term "tiled display:

Google Web Search: "tiled display"
://www.google.com/search?hl=en&ie=UTF-8&q=%22tiled+display

Nothing but the best for pinkfreud---always loved that name.

Thank you very much for the five stars and the nice tip!
