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 :
Polytropon wrote :
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
Hi!
I have the same problem with the same model of TV (Samsung A330). Did
you solved your problem?
Thanks,
Martin
No I haven't solved my problem yet. Still trying to figure out why my TV
display is in 1280x720. When I take a screenshot with 'scrot' i get a
file like this : 2009-03-18-104527_1360x768_scrot.png. But in the
Xorg.0.log it clearly shows the resolution of the TV itself :
term004# cat /var/log/Xorg.0.log | grep 1360
term004# cat /var/log/Xorg.0.log | grep 1280

(II) RADEON(0): h_active: 1280 h_sync: 1390 h_sync_end 1430
h_blank_end 1650 h_border: 0
I tried 'xrandr' in my .xinitrc file, which only affect my
screenshots... I also tried Prefered Mode in the Xorg conf, no effects.
Any tips would be very appreciated ! Thanks.
