For the record: I picked those HSync and VRefresh 
from the /var/log/Xorg.0.log output and the output for the CRT2.
This will be different for each monitor of course.

Note: This setup is not canonical in that I do not know which of the 
settings is actually necessary to make it work and which could be left out.
This is just one I found that worked in getting me a good resolution
on the laptop and the external monitor. 
(Now I have to tackle my rendering problems...)
