Is there any way to get a system with 16 video outputs.
Any hardware that support this that anyone knows of?
It does not have to be any high resolution, just 16 independent
displays.
With PCI Express it should be possible to add an endless number of video
cards and get the same high speed transfer to every one.

Well Matrox has a PCI card that supports for independent monitors, and there
are systems with more than 4 PCI slots.

(1) Yes Don is correct because I worked on these Matrox cards and others
too.
(2) The limit was for 16 monitors or 4 PCI cards as well as I remember.
Each PCI card supports 4 Monitors and had of course 4 Video coprocessors on
it. Note that if all the cards are PCI with no AGP the 2 performance was
greatly increased because of device bit-map caching. This is just for your
info.
(3) Also Matrox has a version with a TV tuner. You only need one of the
boards with a TV tuner. You can then have video running across all 16
monitors as well!
(4) Windows Dos Window also works and will show up on the primary video
monitor.

Martin,
I agree that in THEORY PCI-E would be able to supply you with a solution.
Unfortunately, theory and practice is only the same in theory 
PCI-E graphics cards available today require a 16X PCI-E slot. Most
machines will only have one. Since PCI-E is a point-to-point bus, it’s not
as simple as to just add another slot either. The chipset must have PCI-E
outputs that match the slots. So here goes the practical bit that doesn’t
match the theory… You need to practically find either:
A more likely solution might be to find a machine that has 8 PCI slots and
find some PCI graphics cards with dual outputs. Shouldn’t be TOO difficult,
I would think. You can get extension boxes for PCI bus, so you could extend
the bus to 16 slots too if you’re really desperate.
Or, you could just have 8 machines with dual outputs on each machine (or 4
machines with quad outputs, perhaps). Our company (3DLabs) have a solution
for how to make them all sync up so that one machine isn’t drawing “ahead”
of another one, if you want syncronized output on all machines (this is
synced so that all frames are genlocked and that software is blocked until
the slowest has finished drawing). E-mail me off-list if you want more
details of this, and I’ll forward it to someone who can get you more info.

I work with bowling lane servers, each laneserver handles 8 lanes, each
lane can have one overhead and one LCD console.
Currently we have 2 of our own FPGA “graphics boards” that handle 8
lanes TV signals PAL, NTSC or VGA. But the cards have no acceleration,
it would be nice to have a standard gfx chip with mpeg decoder. It would
also be nice to be able to use a real Video driver…

Video-wall type thing.
DVD-multiplayer?
I’m sure there are other things you could use it for.

(1) Maxtrox also did a solution for Wall Street that is bit different that
does video tiling. The hardware uses Matrox Video hardware which talks to
another company box that then sends the output to flatpanels.
(2) If you use the Quad Boards note that the Desktop would be say a 1 by 16
desktop say. Talk with Matrox about this. The TV / S-Video output is
stretched to the 16 monitors if you wish. The Matrox could easily be change
to clone the TV output to all the screens.
(3) It has been 4 years since I did this work. Contact Matrox in addition.
Sincerely;
Michael Jones

Note that GDI uses 16bit signed numbers for clipping region coords, and
this means - the total size if the virtual surface - regardless of the number
of monitors - is limited by 32K*32K.
