I need to connect 24 monitors to one PC. The requirement is to run different web browsers windows on each monitor for exhibition purposes.
Is there any way to accomplish this mission?
Does anybody know about some kind of splitter that makes this?

The possibilities for 24 monitors are a bit limited. There are Video Signal Splitters, but those will be of no use for you as they can only show the same image as far as I know. There are also graphics cards with more than one output, but that would mean that you need 6-12 graphics cards, depending on the number of outputs your card has. There are Graphics cards with 12 outputs, but I don't see them as really feasible.
Depending on what your Web Browsers have to display, the possible solutions may vary.
Do your Web Browser Windows have to display local files? If so, do these Web Browser Windows have to run on the same computer? If not, you can share your files to other computers, have them display it. This would require 6-12, maybe 24 computers. Those clients could be really thin, you could even use netbooks.
If the Files need to be displayed/run on the same computer, you could use a Remote Desktop Solution allowing more than one screen, like Windows Server has. If you use the Windows Remote Terminal Services Server though you'd have to buy licenses for each unique Session you can show simultanuously. Other free RDP Tools might help you.
For something like that you will need to get specialist hardware, which will be quite expensive.
Since Matrox left the consumer graphics card market, they have concentrated on specialist display technologies, including display walls.
The Matrox Mura MPX Series may be what you are looking for.
Is it a strict requirement that only 1 PC is used to control the 24 monitors? A larger number of PCs with fewer monitors each could be controlled via the use of KVM switches so that you only need 1 mouse and keyboard. Each of these lesser PCs would be relatively simple to set up.
We are using in our company VGA over LAN units that allow you to connect up to 20 screens to a single PC and the screens can be located anywhere in your establishment. Also, each screen is showing different content.
There exist motherboards with 4x PCI-E x16 slots (e.g. MSI X48). If you were careful how you populated that board you could do it, e.g. on that example board:
So it's theoretically possible with off the shelf hardware. That's going to set you back quite a lot though! It would probably be cheaper to get several machines and use software (e.g. Xdmx) to merge them (if you even really want to merge them)
This won't solve your problem completly, but it should help. Matrox has products that multiply your video outputs by three:
They create a stretched desktop with a maximum resolution of 5760 x 1080 (3 x 1920x1080) across three displays.
I think you need more graphic cards because it will be very laggy if 24 screens are running on 1 graphic card. (24 screens on a Intel Core i8 overclocked has still lag so don't try that...)
A tip if you play HD games like COD, GTA or Minecraft, you should use one graphic card for each screen (but if you only need 1 screen for HD games you can also do 1 graphic card for that screen and the other screens use 1 for 2).
A powered USB hub and a bunch of HDMI-USB adapters.
The make, "Plugable", seems to make both a USB hub with a good amount of amps, and a bunch of USB-HDMI adapters.
Apparently may be OK with USB3.
This guy is doing it, not with 24, but there is no reason why he couldn't have another USB hub connected.
You're not going to be able to plug all of them into one box. However, you can build your own virtual 'splitter' out of other machines using XDMX or one of its alternatives.
xdmx - http://www.x.org/archive/X11R7.6/doc/man/man1/Xdmx.1.xhtml It can be complicated to set up but lets you extend your desktop across any number of remote machines. Many people use this to create budget display walls.
There are also alternatives for other OS. Screenrecycler is one for Mac. See other alternatives here: http://alternativeto.net/software/screenrecycler/
Must be a simple task. You need a video distribution amplifier (or 2 or 3 or more depending on the number of channels) http://www.keene.co.uk/electronics/multi.php?mycode=VM92 http://www.mcmelectronics.com/search.aspx?&K=Ce%20labs
Connect all your monitors to it. The input is going to be your computer (you might need splitters for that). Then (depending on the resolution) open multiple browser windows in tile mode in your computer and match them to each monitor position.
Buy several of these http://teqdigital.com/Products.aspx?categoryid=Pdo104&productid=PVW3x31007 and do the same in your one computer.
