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.
"lscpi -nv" outputf for my video card:
