Default LCD TV, SuSE 10.1 No valid modes for "1366x768";

Hi,

I have a Samsung LE40R71B LCD TV connected to my PC running
SuSE 10.1 . When X is started I get only 1024x768 resolution while
the Samsung supports up to 1366x768.
I use the latest Nvidia driver (1.0-8762)
The card is a NVIDIA GPU GeForce4 MX 4000 PCI

From the Xorg.0.log I get this:

(II) NVIDIA(0): NVIDIA GPU GeForce4 MX 4000 at PCI:0:10:0
(--) NVIDIA(0): VideoRAM: 65536 kBytes
(--) NVIDIA(0): VideoBIOS: 04.18.20.38.d7
(--) NVIDIA(0): Interlaced video modes are supported on this GPU
(--) NVIDIA(0): Connected display device(s) on GeForce4 MX 4000 at
(--) NVIDIA(0): PCI:0:10:0:
(--) NVIDIA(0): Samsung (CRT-0)
(--) NVIDIA(0): Samsung (CRT-0): 350.0 MHz maximum pixel clock
(II) NVIDIA(0): Assigned Display Device: CRT-0
(WW) NVIDIA(0): No valid modes for "1366x768"; removing.
(WW) NVIDIA(0): No valid modes for "1280x768"; removing.
(WW) NVIDIA(0): No valid modes for "1280x600"; removing.
(WW) NVIDIA(0): No valid modes for "1024x600"; removing.
(WW) NVIDIA(0): No valid modes for "768x576"; removing.
(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0): "1024x768"
(II) NVIDIA(0): "800x600"
(II) NVIDIA(0): "640x480"
(II) NVIDIA(0): Virtual screen size determined to be 1024 x 768

What does this mean?

Is it the TV that reports wrong size? Is it the card (HW) that can't handle
this resolution or is it the Nvidia driver which can't hadle 1366x768?

I have tried to modify the Modes like this in my xorg.conf file:

Section "Modes"
Identifier "Modes[1]"
ModeLine "1366x768" 180.48 1366 1424 1704 1816 768 770 782 808 #123Hz
Modeline "1368x768_60.00" 85.86 1368 1440 1584 1800 768 769 772 795 -HSync +Vsync
Modeline "800x600" 40.00 800 840 968 1056 600 601 605 628
Modeline "768x576" 33.74 768 792 872 976 576 577 580 596
Modeline "640x480" 23.06 640 656 720 800 480 481 484 497
EndSection

Is there anybody out there who has got the 1366x768 mode to work
towards a LCD TV? How ?

Any help is much appreciated.
