My xorg config is very similar.. first in your server settings:
Section
"ServerLayout"                                                                                           
    Identifier     "Default
Layout"

    VertRefresh     43.0 - 72.0
EndSection                     

Section "Monitor"

    VertRefresh     55.0 - 85.0 
EndSection

..  Monitor 1 is my HDMI out on my TV.

Section "Device"
    Identifier     "Videocard0"
    Driver         "nvidia"    
    VendorName     "NVIDIA Corporation"

    BusID          "PCI:0:18:0"                          
    Screen          0                                    
EndSection                                               

Section "Device"
    Identifier     "Videocard1"
    Driver         "nvidia"    
    VendorName     "NVIDIA Corporation"

    BusID          "PCI:0:18:0"                          
    Screen          1                                    
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Videocard0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "0"
    Option         "TwinViewXineramaInfoOrder" "CRT-0"
    Option         "metamodes" "CRT: nvidia-auto-select +0+0; CRT:
320x240 +0+0"
    Option         "UseEvents" "True"
EndSection

Section "Screen"
    Identifier     "Screen1"
    Device         "Videocard1"
    Monitor        "Monitor1"
    DefaultDepth    24
    Option         "TwinView" "0"
    Option         "metamodes" "DFP: 1280x720 +0+0"
    Option         "UseEvents" "True"
EndSection

Screen1 matches Monitor1 and is set to the default output in the top of
the file under ServerLayout.

Hope it helps.
