 |
|
Hi,
I'm trying to set up this layout:
Screen 0: A Twinview screen composed of:
--A primary monitor connected through DVI.
--A secondary monitor connected trough VGA.
Screen 1: A TV connected trough S-VIDEO.
My card is a GeForce FX5200, it's pretty basic. And this and a search on google lead me to think that it is not possible at all. However, I would like to confirm if my xorg.conf is fine because I'm getting an error and my TV doesn't show anything.
Everything is detected fine in nvidia-settings but the TV (detected as TV-0) is disabled. I can enable it as a separate screen but when I apply the changes nothing happens. Any change done to the other two monitors (DVI and VGA) is used immediately. The error I get in xorg is:
| Code: | (**) NVIDIA(1): Depth 24, (--) framebuffer bpp 32

(EE) NVIDIA(1): Unable to use default mode "nvidia-auto-select". |
I'm intrigued by the line There are only 2 CRTCs available, trimming display device list from "TV-0" to "".
And my current xorg.conf. It was done from inside nvidia-settings, with some modifications. Please inform me of any serious misconfiguration:

I believe what that statement says is true, many video cards, though they have three outputs, can only display to two at a time. The third may be disabled, or at most, a copy of what's shown on another display.

If that's the case, what alternatives are there? Getting a PCI card with TV-out nowadays is quite hard. Is there any brand still selling PCI cards? Even a video capturer would do (I already have one but with no TV output, only input).

pajarete,
if you want TV on your PC, why not try a USB DVB receiver?
If you need some specific cards, you should try the vendors (PCgreen, pricoinsa  ) by calling their commercial guys: they take the cards off the market because there are outdated, but they might keep some cards in their shops. Give it a try!! |

I don't need any specific model. I would do with anything that's compatible with my geforce FX5200.
I don't want TV on my PC, rather the inverse: I want movies from my computer to be displayed on my TV. My old xorg.conf had two screens and this worked wonderful with DISPLAY=":0.1" mplayer movie.avi. The problem is that two days ago I only had two display devices attached at the card, and now I have three and the card doesn't seem to support using simultaneously the three outputs. worse yet, there seems the only cards capable of this are the quadro models and some matrox which are expensive and I'm not sure if those have TV out or just VGA/DVI.
The best solution would be a PCI card but that's going to be hard to find...
