Problem with 1980x1200 @60Hz

[clamilan]

When i make a connection between Samsung T260HD (it does support 1980x1200@60Hz) and my GeForce FX5600 using a DVI-D cable if I set the resolution at 1980x1200 the screen doesn't show all the desktop image leaving an hidden area on the right(or left)...if i move the cursor i can see it as a scroll....with other resolution it works...with a vga cable it works also at 1980x1200...
a graphic card problem? How can i solve it?
thanks

I don't believe that card supports that resolution. I did a search and this is what i came up with.

# Supported Display Graphics 848x480 , 1152x864 , 1280x960 , 1360x768 , 1920x1200 , 1920x1440 , 2048x1536 , VGA (640x480) , SVGA (800x600) , XGA (1024x768) , HDTV (1920x1080) , SXGA (1280x1024) , UXGA (1600x1200) , SXGAW (1600x1024)

but there is 1980x1200....maybe it works only with vga?
