    gnome-display-properties wrongly detects LG42" display size

    Hi everyone

    I have the following setup:
    ubuntu 9.04
    ati 3600HD
    Samsung 22 LCD monitor, connected via DVI
    LG 42 TV, connected via DVI as second display

    all works fine in default config, except that the LG 42 is detected as a 52" display, and so the desktop is larger than the actual screen. if I try to play movies on it, I only see about 60%-70% of the image.

    how can I solve this?
    thanks a bunch!

    $ xrandr -q

    What is the contents of your /etc/X11/xorg.conf file? If it doesn't specify screen sizes, there may be a way to work around it with a Virtual Screen size.

    (Also, it makes technical posts more readable to put [code] forum tags around them.)
