I just got a Samsung 243T with Nvidia Geforce 6600GT (this connection is over DVI). When setting up FC4 , the highest resolution I can choose is 1680x1050. One thing FC4 is doing is that it is using the "vesa" driver by default for my card instead of the "nv" driver. But even once I do select the nv driver in the GUI I still don't see 1920x1200 as a selectable resolution. Going into xorg.conf and puting 1920x1200 as a resolution solves the problem & I X works in 1920x1200.
