I have a GTS 450 and I was wondering if it could run 3 monitor surround on games. It has 2 DVI ports and 1 Mini HDMI port. Right now I have 3 monitors running on both DVI ports(DVI to VGA) and 1 on a VGA USB display adapter. When I start up Chivalry (Steam Game). and only shows up on the main screen. how can I play in surround without getting a new card?
