    You need to put some info into the xorg.conf file to allow mode validation of display against a chosen mode from the internal modes..

    What is the model of display ?
    What resolution do you what to use ?
    My screen is an 22" 22lg30r, and im looking for the 1280X720 HDTV definition. Thanks.

    Re: No widescreen with nvidia board

    I would recommend the native resolution only.. let the video card do all scaling.
    The LG engine is not very good..

    PC-VGA cable your display only supports 60Hz modes (good for US)

    native is 1680x1050
    All possible modes covered by
    hortz freq range 31 - 67 KHz
    vertical freq range 59 - 61 Hz
    GTF timing supported.
    # 1680x1050 59.95 Hz (CVT 1.76MA) hsync: 65.29 kHz; pclk: 146.25 MHz
    Modeline "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync

    add/edit to xorg.conf
    PHP Code:
    Section "Monitor"
        
    Identifier     "Monitor0"
        
    VendorName     "LG"
        
    ModelName      "22LG30R"
        
    HorizSync       30.0 70.0
        VertRefresh     58.0 
    62.0
        Option         
    "DPMS"
    EndSection

    Section 
    "Screen"
        
    Identifier     "Screen0"
        
    Device         "Device0"
        
    Monitor        "Monitor0"
        
    DefaultDepth    24
        Option         
    "ModeValidation" "AllowInterlacedModes"
        
    Option         "UseEDID" "FALSE"
        
    Option         "UseDisplayDevice" "CRT-0"
        
    SubSection     "Display"
            
    Depth       24
    #        Option     "PreferredMode" "1920x1080i60"
        
    EndSubSection
    EndSection 
    You need figure out the screen & device number [0, 1] that correspond to the wired port CRT-0.
    The driver will generate an allowed list of modes from all the internal modes that can be validated against the monitor section.
