UK PAL 16:9 xorg.conf MythTV

[Simoo]

Hi, I thought I would post up the xorg.conf from my XUbuntu 6.10 MythTV box. I have it running on a standard wide screen tv. I had to get info from different sources, hopefully having it all in one place will help someone. If anyone can improve it,post up!

Oh and my /etc/X11/XvMCConfig just contains (without quotes) "libXvMCNVIDIA_dynamic.so.1" so the Nvida card's XvMC decoder works.

Not sure if the whole thing will work as a cut and paste as I might have made errors pasting it up here! But should be a good ref.

Does the DisplaySize thing still work for you in Xorg 7.2.0? It stopped working for me after the update to Feisty.

[Simoo]

Yes it works for me, with out specifying the 'Displaysize' I get a 4:3 ratio. With it the TV switches to 16:9 and I get a full screen pic.

Although I have not updated to X 7.2. I will just run Edgy (6.10) with the official updates for now, I like to stay a distro behind.

Thanks for your feedback. It worked for me too in Edgy. It stopped working in Feisty. I had to add

Option          "DDC" "false"

and

HorizSync 30-50
VertRefresh 58-62

to my monitor section in xorg.conf

H- and VSync are those of my TV.

Cool, thats good to know. Cheers.

Where did you get the info about refresh rates for your TV? My manual had none.

This worked for me:

sudo su
apt-get install read-edid
get-edid | parse-edid

But not all TVs report the edid info.

Hi

I am trying to find out the Horiz/Vert refresh rates for my TV as well (PAL Sony 32" VEGA) and tried to install read-edid but it didn't like the fact I am running AMD64 version of 7.04.

Does the 64bit version exist?

Thanks in advance.
