Initailly i couldn't get anything to display with FC4, I had to connect my old monitor and change the Monitor manually to get the display working with the new monitor. Now I am having trouble configuring 1680x1050 mode.  Everytime I set this my display start to scroll horizontally... Any pointers....

I suspect a manufacturing defect in the 2005FPW that I've been unable to get
Dell to either confirm or deny (or even investigate).

I tried running the X server with -logverbose 20, and I got:

Which translates into:

Modeline "1680x1050" 146.200 1680 1784 1960 2240 1050 1053 1059 1089

but won't actually work if you try it (it drops the top 6 raster lines 
if you do).

So, after a little manual tweaking (or firing up xvidtune), you come to:

ModeLine     "1680x1050" 147.289 1680 1784 1960 2240 1050 1053 1059 1097

which actually seems to work reliably.

Note, though, that the EDID information will confuse some drivers that try
to pay attention to it (some do, some don't).  You'll need to add:

    Option "NoDDC" "yes"

in your "Device" section.

Just out of curiousity, add the "NoDDC" option and try the first 
modeline.  Let
me know if it works or not (if you're running Gnome, then the top of the 
redhat
icon will get clipped if it isn't working correctly... otherwise, there 
will be a white
margin above it).

If it doesn't work, try the second modeline.  This is the one that I use 
with a
Unichrome S3 Pro chipset (on the mobo).
