Splitting a HDMI video feed Vertically

[ArchieChoke]

With the release of gran turismo and the need for seperating two players onto 2 screens so no cheating for the other.
I found this video but im not willing to pay $3500 for this (

Anyone know of cheaper device achieving the same affect?

The problem with something like that is the resolution gets messed up, for eg : 1920×1080 original picture, slice it in half down the centre and you get 2 * 960x1080. Now this will probably be stretched to fill the window (like in the youtube clip).

However that seemed to be an analogue setup using VGA, HDMI would be better and you'll probably be able to get it pillarboxed.
