Default MX440 and TV-out

Hi all,

Sorry to post a so basic question, but is somebody able to get a decent tv-out output with latest nvidia drivers?

I spent last 3 weeks to get a decent tv-out output out of my MX440 integrated card and I'm completely disappointed. I think I tried everything, but somebody has maybe the magic trick to get it working...

Usually, I need 10 minutes to get everything working perfectly, but it seems something has changed with recent NVidia drivers/Xorg.

Here is my software/hardware :
NVidia MX440 integrated (NForce 2 motherboard)
Debian 3.1 (sarge/etch)
Xorg 7.1

This is what I did until now :
- Tried every driver on nvidia site (and Debian repositories) :
7xxx : segmentation fault with Xorg 7.1 (tried all patches on this forum)
8xxx : get strange horizontal lines when using Xvideo (everything perfect with Xshm). This isn't tearing nor interlacing, these are some artefacts horizontal lines appearing randomly on screen (1, 2, 3 to 10 together).
9xxx : horrible flicker and unusable (but no horizontal lines)

- I tried every switch in nvidia-settings (vsync, flicker, ...)
- I tried different kernels (stock 2.6.18 debian, 2.6.19, 2.6.20)
- I tried disabling everything in bios (fast writes, SBA, memory, processor)
- I tried with or without GLX : no difference
- I tried with or without composite : no difference
- I tried every config of NVidia driver

To be sure I have no hardware problem, I tried my old gentoo (Xorg 6.9 and driver 7676) and everything is working right.

I can't understand what is happening with latest NVidia/Xorg driver, something is broken, but what???

I somebody has some ideas on this problem, I would be very happy. To put a second card in my HTTP is not possible and using Xshm get my cpu too hot. I think my last resort is to build a VGA2SCART and don't use the tvout of my card.

What a disappointment as I use it for 4 years without problem with OLD Xorg/Nvidia drivers.

Many thanks in advance and sorry for so long post,

Sarabanjina

Default Re: MX440 and TV-out [interlacing problem]

Well,

I spent another couple of hours on this problem, and I begin to understand what is happening...
Everything seems to be an interlacing problem.

I manage to install an old XFree86 and NVidia 7676 driver and everything is looking as expected.
BUT, I looks like the signal going to the TV set is not interlaced as I see common interlacing lines. When I use a software deinterlacer, everyting looks good.
I tried to define a mode manually (souldn't work for the TV-out as I read) and it works :
ModeLine "720x576i" 13.875 720 744 808 888 576 581 586 625 -hsync -vsync interlace
And guess what : I have strange horizontal lines too!
I guess newest drivers output interlaced signal and not older ones...

I wonder if there is an incompatibility between the interlaced signal from my card and my TV.

What should I do to get the better quality? Output interlaced signal or output non interlaced signal and use a sotware deinterlacer?

Is it possible to output non interlaced signal from my tv-out with newest drivers?

If somebody has same kind of problem, I would be very happy to share my experience with him.

Many thanks,

Sarabanjina

Default [Resolved] Re: MX440 and TV-out

Yesss,

I finally got it working right...

I spent one month on this problem :
- recompiled Xorg
- recompiled Xorg with debug
- tried every driver versions
- tried every bios tweaks
- tried multiple kernels
- ...

My conclusions are (at least for GeForce 4 MX440 integrated) :
- driver 8xxx is broken in XVideo extension
- driver 9xxx is broken in TV-out (flickerness)
- driver 7184 crashes Xorg

BUT, if you remove libvm86.so AND libx86emu.so from your Xorg modules, it works like before (no Xorg crash)! I just watch one hour of divx (non interlaced) and image is perfect, at least...

I have absolutely no idea why it works when you remove these modules, but honestly, I don't care as I have now a good XVideo output from my HTPC with latest XOrg...

I don't understand why nobody reports this problem before (am I alone in this case?), but I hope it will help someone to get a good TV output from MX440 integrated...

Default Re: MX440 and TV-out [b/w image | cable problem]

Good time of the day
I have a problem with my MX440..
os opensuse 10.0, nv driver 9631, old p3-500mhz e.t.c.. I think it is not important..

Everything working perfectly but only without color Machine boot already in b/w mode.

I try tv-out with s-video2rsa cable which came with gforce 6600GT on my new pc desktop, and after it generic svhs2scart but still have b/w image on the screen.

And i want ask u about which cable you connect between tv and pc?
Can u describe pins reference of your cable?

Yes. I`ve got normal colored image using 6600GT on THIS tv (no TVStandart problem).
Yep, u using integrated MX440 Is it based on NV17 tv-coder?

Default Re: MX440 and TV-out

Hello,

I mainly see two reasons to lose color :
- wrong Tv-out standard (PAL-M, ...). You can edit this in bios and in your Xorg.
- SVIDEO output on a TV in composite (try to switch your TV in S-video)

I use a simple svideo cable between my PC and my TV.

Does the 9631 driver really works well on your MX440? Here it works too, but it is unusable as it flickers too much as described here :
http://www.nvnews.net/vbulletin/showthread.php?t=82141

Here is a part of my Xorg log :

Default Re: MX440 and TV-out

my tv cannot be switched to s-video. its too old - no such function.

but using s-video to scart i`ve got normal color output using 6600GT.. so it is not tv problem.

What about 9631 driver.. Hmm.. all works perfectly except color output.
I try to edit xorg.conf with all possible variants, changing TVStandart & TVOutFormat.
No visible results changing this options.

So i think MX440`s embedded tv-out use one another pin to output color info signal.

p.s. Does your computer output in color mode on boot? (bios logos e.t.c.)

Default Re: MX440 and TV-out

Well,

I made some tests for you :
- at boot, signal coming from card is s-video
If I force my TV in composite, everything is black and white.
- in X, when I force composite
Code:
    Option         "TVOutFormat" "COMPOSITE"
colors are back.
- If I put "PAL-M" in Xorg.conf, I lose colors...

I don't think this is a cable problem, as there is only one wire used in composite, and if you see the image, you should get the colors... If you don't see the colors, signal is not composite, but probably s-video...

Yes everythng is in color here, but everything is in s-video...

I wonder if there is a tool to switch the internal config of the card at boot. It should be possible to force it in composite one times for all, maybe with a Windoze tool like TVTool...

Sarbanjina

Edit : I remember that with old nvidia cards, we received an adaptor s-video -> composite with the card. I wonder if it could mix the s-video signal to produce a composite signal, not sure about this...

video card has ability to permanently change tv-out format without phisycal intrusion? cool..

so i need to install winxp on this machine? it has only 3gb harddrive and only wireless card which hard to be used as a backup kit

maybe nv drivers for linux or some other tools like nvtv can help me in this direction?

ehh...

s-video2rca you want to say? something like that:

booo...
i installed win xp and got color output, without any tvtool... with any output format: s-video, composite or scart.
booting still b/w.

xp driver version 84.21
so i have normal working cable... whats wrong with linux?
i try both 8776 and 8774 drivers for X without positive results

I never say it is really possible, but in theory, everything is possible...
Don't install XP for that, 99% probability it isn't possible...

nvtv doesn't support our chip (Chrontel 7009 if I remember well)...

I thought it could be more intelligent, but it isn't...

Your best bet is to leave s-video at boot and manage to get composite in Xorg... I'm sure it works, at least here... You should never reboot in practice

Oups, I miss your last post...

I'm sure it is possible in Xorg, no matter which driver you use.

Are you 100% sure you have these lines in your Xorg with correct format?
Code:
    Option         "ConnectedMonitors" "TV"
    Option         "TVStandard" "PAL-B"
    Option         "TVOutFormat" "COMPOSITE"
I never had any trouble to select S-VIDEO or COMPOSITE with nvidia drivers...
