How to tell the driver my external monitor is a TFT?
 
Hello,

I run a TwinView clone setup, I have an external TFT monitor connected to the VGA out of my notebook. Since the external monitor is connected to VGA, nVidia thinks it was a CRT, but it is a TFT. Do I or should I tell the driver that it actually is a TFT? How do I tell this the driver? Below there is my xorg.conf.

Thanx!

If it is connected via an analog cable, it really is a CRT from the driver's point of view.
