I don't know if it works with all graphics cards, but in my
/etc/X11/xorg.conf file, I have:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Section "Device"
        Identifier  "Videocard0"
        Driver      "nvidia"
        Option      "DynamicTwinView" "False"
EndSection

Section "ServerFlags"
    Option         "AIGLX" "on"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Videocard0"
    Monitor        "Monitor0"
    DefaultDepth   24
    Option         "ConnectedMonitor" "DFP-1"
    Option         "UseDisplayDevice" "DFP-1"
    Option         "CustomEDID" "DFP-1:/home/etc/X11/edid.bin"
    Option         "TwinView" "0"
    Option         "metamodes" "1920x1080_60 +0+0; nvidia-auto-select +0+0"
    SubSection     "Display"
        Depth       24
    EndSubSection
    Option         "FlatPanelProperties" "Scaling = Native"
EndSection

Section "Extensions"
    Option         "Composite" "Disable"
    Option         "UseEvents" "True"
EndSection
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The ConnectedMonitor/UseDisplayDevice options tells it to use the HDMI
output.  The CustomEDID tells it to read the EDID info from a file, which
is useful if my pre-amp/monitor are not turned on before the computer -- my
preamp will not pass EDID through unless both it and the TV are on.
