Sony demos 19-inch FED display running Gran Turismo 5 at 240 fps

FED (or Field Emission Display) hasn't quite caught on as quickly as some other display technologies, but Sony's still out there doing its best to move things forward, and it certainly looks to have turned more than a few heads with its latest demo. Apparently not content with simply showing off a new 19-inch display from its spin-off, Field Emission Technologies, Sony went so far as to demo it with a customized version of Gran Turismo 5 Prologue that's playable at 240 fps. To do that, Sony used four PS3s to increase the frame rate, something it had previously done to run the game at quadruple the resolution of 1080p on a Sony SXHD projector. While that setup is out of the reach of most folks, Field Emission Technologies says that FED displays are now finally heading to market, and that some high-end professional FED video monitors up to 32-inches in size will be available sometime next year.
