Hi Dima,

Thanks for the suggestion, i tried it using:

        Option "IgnoreEDID" "boolean"
                Disable probing of EDID (Extended Display Identification
                Data) from your monitor.  Requested modes are compared
                against values gotten from your monitor EDIDs (if any)
                during mode validation.  Some monitors are known to lie
                about their own capabilities.  Ignoring the values that
                the monitor gives may help get a certain mode validated.
                On the other hand, this may be dangerous if you don't
                know what you are doing.  Default: Use EDIDs.

        Option "NoDDC" "boolean"
                Synonym for "IgnoreEDID"

From: the NVIDIA readme.

But it still doesn't work.

This is a piece of my log:

(**) NVIDIA(0): Depth 24, (--) framebuffer bpp 32
(==) NVIDIA(0): RGB weight 888
(==) NVIDIA(0): Default visual is TrueColor
(==) NVIDIA(0): Using gamma correction (1.0, 1.0, 1.0)
(**) NVIDIA(0): Option "NoDDC" "1"
(**) NVIDIA(0): Ignoring EDIDs
(--) NVIDIA(0): Linear framebuffer at 0xD0000000
(--) NVIDIA(0): MMIO registers at 0xD8000000
(--) NVIDIA(0): VideoRAM: 32768 kBytes
(--) NVIDIA(0): Display Device 0: maximum pixel clock at  8 bpp: 350 MHz
(--) NVIDIA(0): Display Device 0: maximum pixel clock at 16 bpp: 350 MHz
(--) NVIDIA(0): Display Device 0: maximum pixel clock at 32 bpp: 300 MHz
(II) NVIDIA(0): Not probing EDIDs.
(II) NVIDIA(0): Sony: Using hsync range of 30.00-107.00 kHz
(II) NVIDIA(0): Sony: Using vrefresh range of 50.00-120.00 Hz
(II) NVIDIA(0): Clock range:  12.00 to 300.00 MHz
(II) NVIDIA(0): Not using default mode "1856x1392" (hsync out of range)
(II) NVIDIA(0): Not using default mode "1920x1440" (hsync out of range)
(WW) NVIDIA(0): Not using mode "1280x960@100":
(WW) NVIDIA(0):   horizontal sync width (2176 - 1360 = 816) greater than 256
(**) NVIDIA(0): Validated modes for Display Device 0:
(**) NVIDIA(0):      Default mode "1280x960": 148.5 MHz, 85.9 kHz, 85.0 Hz
(**) NVIDIA(0):      Default mode "1024x768": 94.5 MHz, 68.7 kHz, 85.0 Hz
(**) NVIDIA(0):      Default mode "800x600": 56.3 MHz, 53.7 kHz, 85.1 Hz
(**) NVIDIA(0):      Default mode "640x480": 36.0 MHz, 43.3 kHz, 85.0 Hz
(II) NVIDIA(0): Virtual screen size determined to be 1280 x 960
(==) NVIDIA(0): DPI set to (75, 75)

The modeline was created using the modeline command:
modeline -W 1280 -H 960 -z 100:
ModeLine	"1280x960@100" 232.368 1280 1360 2176 2256 960 962 974 1030

As you can see it is ignoring the EDID, but to no effect.
Thanks for any suggestions, if you still have some.

Victor
