OK, first off i want to start off my saying that im in New Zealand so my TV out settings will be different to yours :P
second of all im running a mod of knoppix called knoppmyth which is basically a OS that installs knoppix and www . mythtv . org at the same time as myth is a home theatre PC programe.
i have had ALOT of trouble getting my tv out to work, i can see it on the TV fine when it booting up but as soon as it would go to load myth all i can see is solid white verticle lines (if i dont edit the XF86Config-4, If i edit the XF86Config-4 file by adding the necessary lines i was meant to on the myth installation guide,i get this error.
"(EE) NVIDIA(0): No modes remaining for display device TV-0
(EE) NVIDIA(0): *** Aborting ***
(EE) Screen(s) found, but none have a usable configuration."
thats the best i have really done :s just wondering if anyone has any solution for this, i have tried everything, i have newest nvidia drivers, i have read the TV out readme on there site still nothing, so far about 10 different people have not been able to help :/ im getting worried that it isnt possible and i NEED to get an OS and myth installed and i wouldnt know how to install another OS and then myth, so this would by far be the easiest option.
heres my config.
Identifier "XFree86 Configured"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "PS/2 Mouse" "CorePointer"
# Serial Mouse not detected
# USB Mouse not detected
### Available Driver options are:-
# sw_cursor is needed for some ati and radeon cards
# The following line is auto-generated by KNOPPIX mkxf86config
# BusID "PCI:1:0:0"
Yanc is a very easy way to configure. I used it to get TV-out working for my Nvidia card. The one catch is, I have to be running my monitor in 800x600 resolution while using TV-out otherwise the image will be cut off on the TV.
In the Monitor section because they should go in the Device section.
The MetaModes that you had before was overscanning. What this means is the 800x600 is too big to fit on a 640x480 screen, so you have to move your mouse around to see whats on the screen. The resolution 640x480 is probably the best to use if you want to see the text on the screen. Keep in mind the MetaModes have to relate to what resolution you are viewing at. If you set your resolution to 1600x1200, twinview will be confused because the VGA to TV converter (aka rescanner) can not display higher than 1024x768. You have to add the NULL in MetaMode line if you set your resolution higher than 1024x768.
After you add the lines, logout and hit CTL+ALT+BKSPC. You do not have to reboot your computer for the changes to take effect.
thanks for the help. except i only want to use TV Out not CRT and TV :/ .
i have been mucking around with vert refresh rates and stuff and having the driver set on "nv" i can almost get the picture, at the moment what it does is slowly scrol down the tv and has some horizontal fuzzy lines, but after changing the VertRefresh i can now make out the whole thing like the myth logo etc... but still it's not usable :s with the "nvidia" i just get solid white lines.
TwinView works. You just adding TwinView options in the wrong place. I rather have it set to CRT and TV because its harder to see what I'm doing on a TV. A bit depth of 16-bit will give some dithering. You may want to change it to 24 after you are done. Below is my XF86Config-4 file looks like if you want to see an example.
If I want to output to TV out all I do is hit CTL+ATL+- or CTL+ATL++. If I have set games to play in under 1024x768, it will also output to TV. My ModeLines are in XF86Config.
Some nvidia video cards might have 6 to 9 pins. You have to use the connector that came with your video card or build your own connector. The white lines might be an incorrect TV mode. Try other modes.
