Hi, I am attempting to connect my dell SC420 to a 32" LCD at 1366x768. I have attached my currect config file and currect X start log. How do I massage the xorf file to run at the native resolution of the LCD? It currently runs but is in a virtual mode. The screen scrolls. Any help is appreciated. I am using Centos 4.1.

*Bryan,
the dell sc420 is a poweredge tower. So in this case I wont have to
"worry" about
the laptop LCD not matching the DB15.

I have had nothing but problems with notebooks and Dell i8x0 GPUs when
it comes to the external DB15 port. For some reason the driver will
only send the _exact_same_signaling_ of the internal LCD to the external
port. So unless the external monitor/LCD is capable of the exact same
scan ranges as the notebook's LCD, I've been screwed.
I've been meaning to try my notebook in Windows to see if it has the
same problem. I can only assume the Windows drivers from Intel actually
know how to drive the external DB15 at a difference scan range.
With nVidia Go Mobile chipsets, both the MIT "nv" driver (assuming the
OEM hasn't changed things) and the nVidia "nvidia" driver have no
issue
driving the external DB15 at a different scan range than the internal
LCD.
