Linux Vs. 32inch HDTV [resolution?]


Hi Guys

I've been able to connect my ubuntu 7.10 system up to my TV, primarily for watching downloads etc and possibly wineGaming

Problem is, the resolution doesnt match, so I can't see the bottom taskbar and hence can't full screen any app

I've had a look through the resolution settings on System > Admin > screen resolution and have tried the various formats, but none seem to work

Is there anything I can modify to the system config files to force it to stretch the window?

it looks like the following at the moment

Regards

Have you tried changing the tv resolution to something like 16:9 widescreen or anamorphic.

I have tried every button and setting on the TV+remote that I can see, but none will let me see 100% of the screen

is there anything in my xorg config file that can be altered? or possibly an app that can fit the picture to the screen?

Regards

It may have something to do with your HorizSync & VertRefresh settings in your xorg conf file. See this post here: http://ubuntuforums.org/showthread.php?t=98456 it might give you some clues/settings. Don't forget to backup your current xorg conf before making any changes.

I had a problem like this ages ago when I first got a widescreen TFT and linux had very little support for 16.10 TFT's (around the time of Fedora core 2 I think!) Anyway the problem was with the xorg.conf file and it was this section if I remember correctly

Section "Monitor"
Identifier "Monitor[1]" #TV
HorizSync 30-50
VertRefresh 60
EndSection


I think you need to get the correct values for HorizSync 30-50 VertRefresh 60 from the TV manufacturer sometimes your lucky and a instrcutions have the values - I think I had to find the screen details from a third party and it took me ages!!! - I had to run at 1024x768 instead of 1440x900 16:10 for a good couple of weeks - a good clue will be the refresh rate will be incorrect in screen resolution in gnome. Make sure you back up your xorg.conf if you try different values yourself as this caused me loads of pain when I was doing it... Strangely now in later distributions it appears more simplified - I guess yours just needs a little extra help - also ensure you know the correct resolution for the Section "Screen" - Modes value

Hope this helps

Hi Sm1ler

Thanks for your help, I followed your instructions and it seemed to work OK
(however when rebooted the system had a habit of reverting the settings, so had to type them in again :S)

Anyway, for "future" reference, and for anyone stumbling across this from google, here are my settings...

Inputdevice "Configured Mouse"
EndSection
This is for a VGA - VGA connection from ubuntu 7.10 to a 32inch Bush HDTV on an ATI radeon

Hope this helps
