How can I watch a video in full screen on multiple monitors?
I'm using Windows 7 x64 and I can only make it go full screen on one monitor.

I am assuming that your video card can handle multi monitor. Fire up VLC with the video you want to play then head to Tools/Adjustments and Effect click on the Video Effect tab choose Wall and set how many rows and columns you need to span the video on to.
Example of what it should look like to be able to span the video on to 4 different monitors:
Or you can clone your video across multiple monitors. To do that first you have to disable Overlay under Video Settings in your VLC's Preferences as in the following example:
And then go back to Tools/Adjustments and Effect click on the Video Effect and click on the Advanced tab and choose how many clones you want to have. It should look like this:
I hope this covers the topic. :)
It is possible to do this (and anything else that can be maximized to a full screen) with a hardware solution. This is how corporations (and now, consumers) have been doing it for a long time.
It's better than a software solution, in my opinion, because it would be completely transparant to the software. For all it knows, you just have a really big screen.
For years, you could do this by buying a Matrox Multi-monitor Adapter. This will hook up between your graphics card and displays, and essentially make your multiple monitors appears as one large display to your computer.
These days, you can do something similar with most graphics cards, however. NVidia has their NVidia Surround (which they, these days, term "3D Surround" to show that it supports stereoscopic 3D as well, though you don't need to use it). This will let you stretch a desktop across three displays, driving them from two SLI'd graphics cards.
AMD has a similar technology called Eyefinity. The interesting thing about Eyefinity is that, if you get the right graphics cards, you could theoretically drive up to 24 displays simultaneously, and treat it as a single desktop. However, to get 24 displays, you would have to run a quad-Crossfire setup where each of the 4 cards drive 6 displays.
They actually did this back in 2009 during a demo:
Once you configure the settings in the driver utilities (for NVidia Surround or AMD Eyefinity), you should be able to play your movie in any video player that you'd like, make it full screen, and you'll see it span across all your displays.
Yes, the piece of software I've used to do that is called Ultramon. Here's where you identify that you want all your monitors joined into a single resolution (treated as a single monitor).
