Trouble setting the Primary Monitor (nvidia drivers)

Okay I'm not sure where I should post this but I'll try here..

I have been running two 17" samsung monitors with VGA connectors connected to my graphics card via a DVI converter.
I have always been able to change the 'primary' monitor with just switching which cable goes into which connector in the computer.

However, I recently bought a 24" monitor to change one of my 17" monitors.. Using DVI with this monitor, I cannot manage to change the primary monitor to this new, DVI-connected monitor, no matter what I do. I always get a lot of tearing in videos, unless i disconnect my second monitor (the 17") which is incredibly annoying. I'm using the nvidia drivers, here are the relevant parts of my xorg.conf:

Section "Monitor"

    Identifier  "Philips"

    HorizSync   30.0 - 92
    VertRefresh 50-160
EndSection

Section "Device"

    Identifier  "6800GT"
    Driver "nvidia"
    Option "TwinView" "true"
    Option "RenderAccel" "true"
    Option "AllowGLXWithComposite" "true"
    Option "NoLogo" "true"
    Option "TwinViewOrientation" "LeftOf"
    Option "SecondMonitorHorizSync" "30.0-81"
    #Option "SecondMonitorHorizSync" "74.8"
    #Option "SecondMonitorVertRefresh" "70"
    Option "SecondMonitorVertRefresh" "56-75"
    Option "TwinViewXineramaInfoOrder" "DFP"
#    Option "MetaModes" "1920x1200,1280x1024;1280x1024,1920x1200"
    Option "MetaModes" "1280x1024,1920x1200;1920x1200,1280x1024"



    Option "UseEdidDpi" "false"
    Option "DPI" "81 x 81"

Section "Screen"
    Identifier  "Screen 1"
    Device      "6800GT"
    Monitor     "Philips"
    DefaultDepth 24

    Subsection "Display"
        Depth       24
        Modes       "1920x1200" "1280x1024" "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection
EndSection

Any help would be greatly appreciated. Note that what I want is to have the metamodes say "1920x1200,1280x1024", the "TwinViewXineramaInfoOrder" doesn't actually change the primary monitor.

Update: I was thinking that I could change the "Sync to Vblank on display device" in nvidia-settings to my dvi connected monitor, however, that just tells me:

ERROR: The attribute 'XVideoSyncToDisplay' specified on line 50 of configuration file
       '/home/insertusernamehere/.nvidia-settings-rc' cannot be assigned the value of DFP-0 (the currently enabled display
       devices are CRT-0, DFP-1 on nodame:0.0).

Any ideas why not? Are the nvidia drivers just really bad? :S
