Hi everyone,

I got this TV : 
http://www.samsung.com/ca/consumer/detail/spec.do?group=tv&type=tv&subtype=lcd&model_cd=LN40A330J1DXZC&fullspec=F

I'm trying to use it as my screen under FreeBSD 7.1-RELEASE with a 
resolution of 1366x768 which is suposed to be suported by the TV, 
acording with the TV's specs. I did the same with another very similar 
TV and it was working #1 without having to create any Xorg.conf, a plain 
startx and the display was perfect (1366x768).

With my new TV, X only start in 1280x720. So I created a config file 
with Xorg -configure, then I tried to force Xorg to use 1366x768 but it 
keeps loading in 1280x720. In my Xorg.0.log it looks like there's no 
support for the resolution I want :

[...]
(==) Using config file: "/etc/X11/xorg.conf"
[...]
(II) RADEON(0): Panel infos found from DDC detailed: 1280x720

[...]
(II) RADEON(0): Output DVI-0 using initial mode 1280x720
[...]

This is how i configured my resolution in my /etc/X11/xorg.conf :
[...]
Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        DefaultDepth 24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes   "1366x768"
        EndSubSection
EndSection
[...]

My video card is a Radeon HD 3450 and my Xorg version is xorg-7.3_2

Also, the only other resolution "supported" by the TV according to the 
log file would be 1920x540...but it's not supported by the TV !

Am I missing something ?

Thanks for reading.

Francis
