When I took the easy way it configured mine wrong.

You may need to select "advanced" and manually configure scan 
rates and resolution, eliminating those that work but poorly.  
I recommend looking in the monitor manual and selecting scan 
rates in a narrow range so it can only choose the one you want.

When I left the range wide, it chose 1280x960 on a 1280x1024 
monitor, even though 1280x960 was not listed as a proper 
choice and 1280x1024 was.  This resulted in a vertical smear 
over the whole screen.

Another option is to manually edit /etc/X11/XF86Config-4 .  
Just specify the exact rates you want, and take out the others.

Another comment on TFT monitors ....   It is not enough to 
match the scan rates.  Every pixel needs to line up, in the 
correct phase, otherwise you get smearing.  It must be exact.  
Most monitors have a means of automatically matching it.  You 
might need to activate it by pushing a button on the monitor.
