I was thinking about how I used to see large TV "stacks" where one image was distributed across several TVs to make one large display. I am looking for something that will split the signal like this into 4 displays.

I dont want a large display but I was thinking of it more along the lines of "hardcore Goldeneye" or something of that nature. A two way (top and bottom) splitter would also be of a little interest, although that would change the aspect ratio of the images.
