Resolution problems

I'm running a dual monitor setup off of a Nvidia GTS 250. My old Compaq screen is running fine at it's maximum resolution, 1024x768. But my problem is my Soniq HDTV. According to nvidia-settings it's maximum resolution is 1920x1080. I can set it to this and others but everything above 1024x768 wont display the whole screen. There seems to be about an inch above and below that i can't see.

The screen does the same thing in Windblows but can easily be fixed with nvidia control panel. Unfortunately there is no tool like the one to fix it (that i can find) on Linux.

Any help would be appreciated.

Hi -

Did you look here:

The NVIDIA Driver includes a utility called nvidia-xconfig, which is designed
to make editing the X configuration file easy. You can also edit it by hand.


nvidia-xconfig will find the X configuration file and modify it to use the
NVIDIA X driver. In most cases, you can simply answer "Yes" when the installer
asks if it should run it. If you need to reconfigure your X server later, you
can run nvidia-xconfig again from a terminal. nvidia-xconfig will make a
backup copy of your configuration file before modifying it.

Note that the X server must be restarted for any changes to its configuration
file to take effect.

More information about nvidia-xconfig can be found in the nvidia-xconfig
manual page by running.

% man nvidia-xconfig

I have run nvidia-xconfig before but have never looked at the man page. It seems there are some interesting flags i could try out. Thanks for the tip. I'll let you know how it goes regardless if i solve it or now. Thanks again!

I've tried what i can but there is still no change.
Here is the relevant parts of my xorg.conf

Section "Monitor"

Identifier "Monitor1"
VendorName "Unknown"
ModelName "MLK"
HorizSync 28.1 - 67.4
VertRefresh 50.0 - 60.0

Section "Screen"
Identifier "Screen1"
Device "Device1"
Monitor "Monitor1"
DefaultDepth 24
Option "TwinView" "0"
Option "TVStandard" "HD1080p"
SubSection "Display"
Depth 24
Modes "1712x1036"
The display 1712x1036 is what windows sets it to when fixing it with the tool mentioned earlier. That option is not available however anywhere. Also the TVstandard seems to be ignored too. When i press the display button on the tv's remote is says it's running at 720p. When pressed in windows it says 1080p.

If you need more information or have any advice please don't hesitate.
