Nvidia tv out xorg.conf


Hey, my xorg.conf is below and what I want to know if possible how to get rid of an inch thick boarder on the right and top sides of my tv screen?

and could someone show me where I should put the "SVIDEO" and "PAL I" options in the xorg.conf and any other options you may think I will need.

nvidia driver TV-OUT config ideas

I'm guessing the border you're seeing is caused by those:
Code:
    HorizSync       28.0 - 33.0
    VertRefresh     43.0 - 72.0
In the monitor section for the TV. Those figures, combined with whatever resolution is being chosen by X, is probably making the image a funny dimension. I found my (non-high-tech-flat-HD-digital-super-whatever) TV worked fine at 1024x768 and wouldn't go any higher anyway, so maybe specifying a particular resolution for the TV might help? Just speculating, but if nothing else works, give that a try.

As for the PAL and SVIDEO stuff, the most perfect place to read about using these options for with nVidia driver, is the nVidia README that comes with the driver, especially the TV-OUT section (section 16) for starters. You can find it here:
http://us.download.nvidia.com/XFree8...DME/index.html

You may like to have a look at the xorg.conf files I've posted over here, for reference too, specifically see post #3 to see some TV-OUT options I used in the last "screen" section:
http://www.linuxquestions.org/questi...nitors-751939/

Best of luck - let us know how you make out or if still stuck, tell us what you've tried or paste us the new xorg.conf file to have another look.

@GrapefruiTgirl Thanks for the reply.

Cool will look through those in depth a little later, I have just made a couple of additions to my xorg.conf file at the bottom in the Screen1 section which have improved my picture quality a lot so thanks:

    EndSubSection
EndSection
and at the top were I had:

Code:
    HorizSync       28.0 - 33.0
    VertRefresh     43.0 - 72.0
I just removed it from the file. was that ok or was i supposed to change the values as it did not do anything for the black boarders, they are still there.

The file looks good to me. I'm not sure what to tell you about the black border thing, but here's a bit more info or more questions:

1) What kind of TV is this? Old, or new? CRT or flat LCD?

2) The HorizSync and VertRefresh entries are a good idea to put in there. With modern "intelligent" equipment, these things can be auto-detected with some reliability, but on older hardware, like old CRT monitors, it was possible to damage the hardware if the frequencies were too far out of whack. Better safe than sorry I figure; I suggest get the appropriate numbers (or range) for your TV from the manual or the website of whoever made it, and put those back into the file.

3) I have not tried this so it's only an idea: On that README page I linked to, in section 16, they mention the "TV overscan" option, which appears to be for enlarging or shrinking the image. I don't know why one would normally want to do this, but maybe it could enlarge the image you see and get rid of the black borders??

4) Can you possibly try "COMPOSITE" instead of "SVIDEO" if your TV will work with that? I found I got a crappy picture with SVIDEO, but looked better using "COMPOSITE". Maybe you would too, who knows.

Well, that's all I can think of for now.. Keep us posted about the black borders.. Someone else may have a better idea later.
