An update released on 18 February 2011 for Gran Turismo 5 not only fixes a number of bugs, but introduces one big new feature, namely support for multiple monitors.
Hardcore GT5 players can join three or five high-definition televisions together for an extended field of view. This, however, requires an equal number of PlayStation 3 consoles and copies of GT5, as well as a high-speed Ethernet hub to link up all the hardware.
There are some caveats, though. The multi-monitor function is incompatible with two-player split-screen mode, B-Spec races and DIY tracks created by the course maker. Check out the video below from the Taipei Game Show for a quick demonstration of a GT5 five-screen set-up.
If you're still keen, or just curious, Sony has posted up detailed instructions on how you can set-up this multi-monitor configuration.
