flicker in picture. Tv out.

[startail]

I have the same problem

Whenever I try to do something on the TV the screen gets all flickery and jerky.
It has worked great in previous versions of the driver. Like 4496 (I think it was)
But now whenever something birght (white etc) comes in the picture it starts to jump and it's impossible to work with it.

I've tried OverScane "0.0" and up to "1.0" but no effect.

It's a Nvidia Riva TNT2, 32Mb with TV-Out over SVideo.

Hello there. I have also flickering tv-out when watching a movie with a lot movement.

My Hardware is this.
P4 2,4Ghz
Intel 850 motherboard
Geforce FX5600 (MSI with VIVO)
1024Mb RD-ram.

I have configured my tv-out as a second X monitor, (not using twinview).
I think that it says in the README-file for the nvidia-driver that hardware acceleration is only supported on the first screen (screen 0).

From the readme-flie:
"While there are several disadvantages to this approach as compared to
TwinView (eg: windows cannot be dragged between X screens, hardware
accelerated OpenGL cannot span the two X screens), it does offer several
advantages over TwinView:

o If each display device is a separate X screen, then properties
that may vary between X screens may vary between displays (eg:
depth, root window size, etc).

o Hardware that can only be used on one display at a time (eg:
video overlays, hardware accelerated RGB overlays), and which
consequently cannot be used at all when in TwinView, can be
exposed on the first X screen when each display is a separate
X screen.

o The 1-to-1 association of display devices to X screens is
more historically in line with X."


When watching a movie (mpeg or avi) with mplayer or xine, on my monitor the quality is perfect but when I start mplayer and use DISPLAY=:0.1 to get the movie on the tv-out it flickers.

Is there any possibility to get th TV-out as the first monitor and use VGA as second.

Sorry for my bad english.

I hate this, using my 440 & TV-OUT the screen is very flickery, doing things like watching movies, surfing the web, well just about anything....

I fought with the various modes and overscan. Really the problem is caused by NVidia not having exposed anti-flicker features via the Linux drivers!

Man... Nvidia's linux strategy... blew...

Who do I write to complain?

What I posted earlier in this thread I think I've solved, but I'm not happy really.

I tested another tv to see if it was my card that was getting damaged or the tv, and the other tv worked just fine. It's an older tv, must be 5 or 7 years old I think. But it worked on it. So I think my tv is damaged on the Svideo-In port.

I've read on most part of this forum that most people that has flickering problems have had flat screen (plasma or tft screens) and my tv is a "normal" samsung tv. So I guess I just have to get a new tv again.

Did anyone manage to solve the problem, when i play movies i get a line running through the picture at certain intervals.
I think that it may be an interlace problem but how do we solve it. I have a geforce fx 5200.
Whatever help will b appreciated

Only Nvidia can solve the problem by providing flicker reduction features in the driver...

To bad there support email doesn't respond...

Nvidia!!! Give us linux geeks flicker reduction for TV OUT please
