resolution problems with X

[cbobby]

I have connected a tv to my computer using hdmi. I'm running natty with nvidia drivers and I created the xorg.conf file using the nvidia control panel. However, I'm not able to change the refresh rate of my monitor since only some crappy rates (50, 51, 52...) are available. X tells that the current refresh rate is 50 but in reality it is 60 (which is not in the list). The xorg.conf file contains:

Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
Option "Xinerama" "0"
EndSection

Section "Files"
EndSection

Section "InputDevice"
# generated from default
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/psaux"
Option "Emulate3Buttons" "no"
Option "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"

EndSection

Section "Monitor"
# HorizSync source: edid, VertRefresh source: edid
Identifier "Monitor0"
VendorName "Unknown"
ModelName "SAMSUNG"
HorizSync 26.0 - 81.0
VertRefresh 24.0 - 75.0
Option "DPMS"
EndSection

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "ION"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "TwinView" "0"
Option "metamodes" "nvidia-auto-select +0+0"
SubSection "Display"
Depth 24
EndSubSection
EndSection

which I think is correct. Any suggestions what might be wrong?

Run nvidia-settings.
