How to setup S-Video

Hi

I recently installed Arch for the first time. And now I want to get the S-Video Port get running. But I have no idea where to start. Do I need drivers for it and if so which one do I need? Maybe it is only a setup issue. In the settings area I found under "display" that it is possible to detect other screen / displays. But after connecting the cable between the TV and the laptop I get nothing one the TV, the additional display is not detected. What do I have to do?

thanks

Re: How to setup S-Video

You do realize that the best resolution you're going to get out of an S-Video connection is about 800x600 and a standard-definition signal too?  As in hooking it up to an old CRT tube TV.

See if the head for it is visible to your graphics driver.  For that use: Xrandr and post back with the output of that command.  If you do see your S-Video output then using Xrandr you could probably get it working and then you don't have to post the output of it but can just move straight on to marking your thread [Solved]. wink

Re: How to setup S-Video

Sometimes you have to have it plugged in before you start X, or it won't even consider using it.

Re: How to setup S-Video

We should first start with the most important thing: AVFritze, what GPU do you have? That it still has s-video suggests it's oooold, which means it may not support xrandr. And that means using configuration that's specific to the GPU driver, which you'll find in the driver's manpage.

@headkase: Usually 1024x768 will work too. However, whatever resolution you set, it'll get downscaled to 480i or 576i, so using a lower resolution might actually be better. Standard graphical interfaces will be almost unusable either way, between the downscaling, interlacing and the anti-flicker filter, small text becomes unreadable.

Re: How to setup S-Video

Ok, i915, nothing special about that (if you had some SiS or S3 or VIA or Matrox thingy, that would be more fun). Learn to use xrandr, there's plenty of info about it everywhere. I see headkase even provided the link to the relevant wiki page.

Re: How to setup S-Video

well I don't find any specific to S-Video there. I found this Page https://wiki.archlinux.org/index.php/ATI#TV_out
But this assums I have a S-video output detected with xrandr but I have not. I have only this TV1 and I don't know if this the same as the S-video.

Re: How to setup S-Video

How many physical TV type outputs does your particular card have?

Re: How to setup S-Video

I found the following on the Ubuntu- Forum, tried it out but no effect:

[AVFritze@Arch-Host ~]$ cvt 800 600 50
# 800x600 49.92 Hz (CVT 0.48M3) hsync: 31.00 kHz; pclk: 30.75 MHz
Modeline "800x600_50.00"   30.75  800 824 896 992  600 603 607 621 -hsync +vsync
[AVFritze@Arch-Host ~]$ xrandr --newmode "800x600_50.00"   30.75  800 824 896 992  600 603 607 621 -hsync +vsync
[AVFritze@Arch-Host ~]$ xrandr --addmode TV1 "800x600_50.00"
[AVFritze@Arch-Host ~]$ xrandr --output TV1 --mode "800x600_50.00"

I'm assuming that TV1 points to the S-Video port

Re: How to setup S-Video

Some video cards will only use VGA1 or TV1 but not both at the same time.
