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 :
[...]

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

I had this problem last month, I tought it was fixed using this little
trick suggested by Polytropon :

If it doesn't work, there's always an option to use xrandr via
~/.xinitrc:
xrandr --size 1366x768 &
xrandr --fb 1366x768 &
I have a similar issue with the "ati" driver, using an ATI Radeon 9200
(RV250) which I need to force to 1400x1050 (worked with old XFree86
and the setting in the config file, as you mentioned it). The
autodetection of the screen (21" CRT) leads to stupid values that
are completely unusable.
The screen is located far from my office so I can't be in front of it to
test, that's why I haven't spotted it wasn't working. I tought it was
because when i take a screenshot with 'scrot' i get a full screenshot in
1366x768 and everything is clean, but the TV itself shows a 1280x720
display. I should've watched the Xorg's log instead of simply assuming
it was working with a screenshot, but anyway now my problem is the same
: The PC is configured in 1366x768, but the TV don't care and shows a
1280x720.
Anyone got a similar issue and a way to fix it ?
Thanks,
Francis Dubé
