Is this Dual Play issue existent in all the titles you've tried or just the FPS type games?
The dual play function works. But for some reason it thinks my tv is a lot bigger than it is. Mine is 55". But when I put the dual play on everything ends up bigger and half the picture ends up of screen. Which sucks coz I get shot heaps by people I can't see.
Does anyone know how to configure the dual play?
