Hello,

I am using my 2 19" TFT Monitors, it works but only to 2x 1024x800 (2048x800).
I Need 1280x1024 for a clear view on my TFTs.

Off hand, I'd say if I was messing with the file, this is where I'd start:

DisplaySize 752 301 #SamsungTFT horizontal size *2 to get 86*86 dpi

you can fix that dpi the correct way by using

Option "UseEdidDpi" "FALSE"
Option "DPI" "86 x 86"
--You talk the talk, but do you waddle the waddle?
