Screen size settings

[houghi]

Hello,

I have a GeForce GT 520 Nvidia that I had connected to 2 1920x1080
monitors. I used the VGA connection
I also have a GeForce 8400GS NVidia that I have connected to two 1920x1200
monitors. I use the VGA connection.
I have xfce 4.10 and run Debian Jessie

I used to configure all with nvidia-settings, but for some reason that is
not included in Jessie anymore, so I need to do things manually.
All worked perfectly and I had a working xorg.conf

Now I want to use the HDMI connection on the GT 520 instead of the 2xVGA.
Here is the thing: I get it to run in 1920x1080, but I do not see
everything. I only see part of it. Bit hard to describe, so here is a
background image I made : http://houghi.org/XFCE/test.png
It is 1920x1080. I do see it all when I use the VGA connection, but not
when I use the HDMI conection.
What I see is nothing of the white border and only a bit of the yellow.
(If need be, I can take a photo and put that online.

I have tried it on three different monitors from three different brands,
so it is not that. My xorg.conf can be found here:
http://houghi.org/XFCE/xorg.conf

I also tried using xrandr:

   1280x1024     60.02  
   1280x720      60.61    59.94    50.00

   800x600       60.32  
   720x576       50.00    50.08  
   720x480       60.05  
   640x480       59.94    59.93  


I tried using 
`xrandr --output HDMI-0 --rate 60 --mode 1920x1080 --fb 1920x1080 --panning 1920x1080`
and that did not change anything.

Using "Display Settings" does not have any influence either. I still do
not see the whole desktop.

What else can I do? What other information do you need?
