Question screen is only black and white and using nvtv does not change anything

Hi,

starting my linux system attached to tv (and not to any monitor) X starts up in black and white.
I tried to change settings via nvtv, but no visible changes happen.

My system is a PIII with a Leadtek Geforce 4 MX 440 and I'm running a Suse 8.2 system.

I forgot to mention, that this happens with the driver 4363.

The video BIOS is 04.17.00.24.00 and it's an AGP-video card.

Note: the system is intented to be connected alternatively to a tv or a monitor. Attached to the monitor, I've no problems.

Many thanks for your hints.

Unhappy I have the same problem

I have nearly the same systemconfiguratin as U. What I red in the Suse 8.2- Dokumendation (/usr/share/doc/packages/nvtv/FAQ/2.1) is that that is a known problem. I am still searching for a result of this problem. I don?t know if it is a solution - using "NVIDIA-nforce-1.0-0256.suse82.i585.rpm" which is also available at www.nvidia.com

kind regards

Default Same Problem with WinFast2

Hi Sobi,

I had the same problem with a WinFast2. When reading the documentation of (latest) NvTV version I found a hint that perhaps the msc value has to be adapted when BT686/689 Brooktree chips are used.

I was able to fix this problem by selecting NvTV page "BT Regs2" and tuning msc register values. In my version "msc" it is the last entry in the first row of values.

With my card a value of 6455 for first msc register brought me color which is only 1 above default value (6454). Don't forget to click Apply after every change or use AutoApply.

I hope this helps.

This is the text I found in documentation to NvTV 0.4.4:

On some systems, especially with Chrontel encoders, the frequency of
the color carrier is wrong. You can change this frequency with the
two 'fsci' spinbuttons on the Chrontel register page, and similarly
with the 'msc' spinbuttons on the Brooktree register page. Don't
forget to 'Apply' or 'AutoApply' your changes. If you need to change
this value and find ones that work for you, please mail me the mode
and the values. There is also a 'pseudo' TV system called 'PAL-X'
which has a few modes with different color carrier. Maybe those work
for you, maybe they don't.

Thanks for your reply and your hint!
Could you please send me a link to this driver?
The latest driver I could find at nvidia.com is the 1.0-0248
I suppose, that 1.0-0256 is a newer release, but I couldn't find it.

to Ralph
You wrote, that the behaviour could be a timing problem.
Do you know, whether there's a way to change the timing in XConfig or so?
nvtv seems to not recognize the TV.
Whatever setting I change, no reaction on tv.

Many thanks for your replies.

regards

Geronimo

Thanks to your hints I found out, that the TV-Encoder of the Geforce 4 Cards are not supported by nvtv.
Starting nvtv, it says in the config page at TV-Encoders: <no device>

In the logfiles I found, that the actual nvidia-driver (4363) is compiled against XFree 4.0.2 - whereas Suse 8.2 is running XFree 4.3.0
I've no idea whether that has any importance or influence ...

Another point is the warning, that the driver failed to read the EDID parameters (whatever that is).

Having both displays connected, I found an entry in the logfile:
connected display devices: CRT-0, TV-0
multiple displays connected, but only one display allowed, using first display...

No idea, whether this is normal, but if so, I know understand, that it could not work without the support of nvtv.

I think we have to await a new Release of XFree or nvtv or even of both ...
