Nvidia, Twinview and Samsung Syncmaster

I bought a new Samsung Syncmaster T200 and wanted to configure Nvidia's Twinview. Once plugged in, nvidia-settings told me my new screen's native resolution would be 1024x768. WTF?

Well, after 2h googling and asking on IRC I found some page about custom EDIDs (with that the screen can tell your computer which resolutions it supports and so on). Everything I had to do was dumping the EDID of my first screen (using nvidia-set) and adding Option "CustomEDID" "DFP-1:/etc/X11/dfp1-edid.dat" to Section "Device" in xorg.conf.

Here you can download my EDID file if you don't have one.
