Horizontal Span vs Dual View on nvidia

Vista still dosent support Dual Span
Nvidea sayes we droped it cuz of Driver Specs..
and Mircrosoft says we dropped it cuz to many Errors..
unfortantly i think no there wont be an option in Future for Vista... cuz Vista is death because of Windows7
Dual View only extents the Desktop
not the View in Games wich is only one monitor
if u have 2 Montiors for Gaming Vista sux...
only option u have buy a slow Matrox trippelhead wich can...
As long Vista has no Dual Span its Death for me..
on the other Hand i understand why, they want games on Xbox.. but Xbox hast 2 Monitors ?
guess the switsched to many Gamesouroundingengeniers to the Xbox and forgott to think this feature through...
and thats why Vista dies...
most people wich use Mircosoft play also games on it...
if games dont work, they dont buy..
