Sounds to me like you have subpixel smoothing turned on for the wrong 
type of subpixel ordering, and/or the nvidia driver may not be giving 
you the correct resolution. Check your /var/log/XFree86.0.log file for that.

My Toshiba Satellite Pro 6100 has a native resolution of 1600 by 1200, 
but the nvidia driver thinks it only supports 1400x1050. To change that 
I had to add this line to /etc/modules.conf:

options nvidia NVreg_SoftEDIDs=0 NVreg_Mobile=2

You'd have to change that final 2 to a 1 for Dell laptops, according to 
the nvidia README file.

Also, you may have to add these two lines to the "Device" section for 
the nvidia video card:

Option	    "IgnoreEDID" "1"
Option	    "UseEdidFreqs" "0"

Hope this helps.
