Problems with nvidia and hdtv

Hello,

i'm having troubles using a specific TV (Metz) as monitor for my netbook.
graphics card is nvidia ION, netbook is Samsung N510.

There is no problem connecting to my Acer Monitor or my Grundig flat TV via HDMI and nvidia-settings - sound does also work.
When I try to connect to my parent's Metz TV it just don't work. I tried out every combination of 1920x1080 or 1360x768 resolution and every possible refresh rate in nvidia-settings - got no picture.
But sound does work on the Metz TV.
When I used Windows 7 it had no problems on that TV.

Does anyone have an idea? thx

have you read our archwiki on nvidia ?

I was only searching for hdtv/hdmi stuff... so I didn't mention the part about refresh rates at the bottom of the page.
The TV seems to have problems with a rate of more than 50Hz

I simply tried to disable the laptop monitor and using only the TV at 50 Hz, but then I found that xrandr still uses a rate of 89 Hz (the TV can now show about 25% of the screen in the upper half part of its screen, the rest is just garbage; but i can read console outputs). I executed "xrandr -r 50", but it told me there would be no support for 50Hz.

add it in xorg configuration file OR (example from: man xrandr) force it

EXAMPLES
       Sets  an output called LVDS to its preferred mode, and on its right put
       an output called VGA to preferred mode of a screen which has been phys‐
       ically rotated clockwise:
              xrandr  --output  LVDS --auto --rotate normal --pos 0x0 --output
              VGA --auto --rotate left --right-of LVDS

       Forces to use a 1024x768 mode on an output called VGA:
              xrandr --newmode "1024x768" 63.50  1024 1072 1176 1328  768  771
              775 798 -hsync +vsync
              xrandr --addmode VGA 1024x768
              xrandr --output VGA --mode 1024x768

       Enables panning on a 1600x768 desktop while displaying 1024x768 mode on
       an output called VGA:
              xrandr --fb 1600x768  --output  VGA  --mode  1024x768  --panning
              1600x0

       Have  one  small 1280x800 LVDS screen showing a small version of a huge
       3200x2000 desktop, and have a big VGA screen display the surrounding of
       the mouse at normal size.
              xrandr --fb 3200x2000 --output LVDS --scale 2.5x2.5 --output VGA
              --pos 0x0 --panning 3200x2000+0+0/3200x2000+0+0/64/64/64/64

       Displays the VGA output in trapezoid shape so that it is keystone  cor‐
       rected when the projector is slightly above the screen:
              xrandr     --fb     1024x768     --output     VGA    --transform
              1.24,0.16,-124,0,1.24,0,0,0.000316,1
