Hello, Im new to the forums.

Im having trouble with the tv out function on my video card when trying to adapt it to composite.

Here is what I know, I know that the adapter works... since I used it in windows and was able to clone my desktop through it. Also I know that the svideo out works, since when I set the Options "TVOutformat" "SVIDEO" and use it without the adapter directly to the TV. However, when I use the adapter and try to run the tv out through my vcr it doesnt work. Nothing.

I have to use the VCR because my current tv has no composite or svideo.

Im not sure what Im doing wrong I have been all over reading, however I might have missed something and a second opinion is nice. It has been driving me nuts.

Im not that good with this sort of thing, I have linux experince... but I cant figure out this adapter problem any help will be much appericated.

Also things I have tried, I have set the options to "COMPOSITE" and "COMPONENT" will no luck, also was trying to get clone view working with twin view, if anyone can help me get past this adapter problem I could work on that,

anyways thanks,
Neto.

I do all of my installs using a tv only and selecting the tv boot option. However when I tried to do this using an RF modulator (vid card svideo->svideo to composite adaptor -> composite input of modulator), the TV card would not detect that I had the TV out plugged into anything, and it attempted to use the VGA out instead (which meant I saw nothing).

Using a multimeter, I measured the resistance of the modulator's composite input compared to the resistance of a TV's composite input and the tv was 75 ohms and the modulator was open circuit. I then connected a 75 ohm resistor across the composite input to the modulator, and my video card suddenly realised that it had a device connected to its TV out, and it output the signal to it and all was hunky dory.

So are you saying the signal is weak or something? hmm I have had this problem in windows I think... is there a way to force output through the svideo connection?

Im horrible at basic electronics... I dont even own a multimeter, but in my understanding did you use the meter to amplify the signal to the RF device? Thus helping it get detected?

Also would I be able to continue using the vga? while also cloning the display of the vga to the svideo?

All I was really saying is that if it auto-detects that you are connected to the tv out (and not a monitor), things can be a lot easier (i.e. tv out will work automatically because the tv out will be your primary display). I was also warning that there may be some circumstances where it will not correctly detect that you have something connected to the tv out. If you want to clone or use twinview, you will have to work out how to configure it.

The meter was only used for diagnosis, not as some sort of signal amplifier.

I highly suggest you do not use clone view and you set the ConnectedMonitor TV and TVOutformat COMPOSITE options, and only connect the tv.

Twinview can be accomplished, but it has several drawbacks and is really not worth the trouble to set it up, but if you are determined there are a few threads about it, with example config files.

Thanks alot for replying,

I have tried setting the

Options "ConnectedMonitor" "TV"
Options "TVOutFormat" "COMPOSITE"

With no luck, my monitor turns off likes its going to work however nothing gets displayed through the svideo connection.

But when I change it to

Options "TVOutFormat" "SVIDEO"

and then hook that directly into the svideo on the tv it works fine, infact it It works from the beinging POST of my BIOS...

Twinview isnt really important to me, it was something I wanted in the mean time to work with. I still need a tuner card...

Maybe Im just spinning my wheels trying to get this svideo to composite adapter working, most tuner cards have composite out right? or is it composite in?

Im still unsure on what tuner card to get. Which card do you guys recommend with knoppmyth with as little hassle as possible with a remote?

Anyways thanks again for all the help guys,
Neto

I just reread your post Xsecrets

Are you saying that using the adapter to switch the svideo to composite hook the composite connection into the TV's composite input? That might work I havent tried that on the TV im using.

The TV im using only has coax in, I have to use the vcr to change to coax, the vcr has only composite and coax options, my video card only has svideo out.

so Im trying to go from SVIDEO --> COMPOSITE --> COAX .

Its probly not to smart to do it this way, however it should still be possible right?

If it doesnt sound like a good Idea, I would like your recommendations.

Thanks,
Neto

I'm not sure if this will be helpful, but i thought i'd toss it your way anyway.

I have had problems before with not using the proper tv-out cable from my video card - which took me a while to figure out. It turns out that there are basically two types of s-vid that can come out of a video card. one has 7 pins and the other only has 4. this link illustrates it well:
http://ghearing.com/?Gabe:ATI_All-In-Wonder_Pinout:SVideo_Pinout

basically, if you have a 7-pin version then you might need the proper 7-pin "dongle" that pulls down on one of the lines to let the video card know that a source is attached. the above link is misleading in that i think the 3 "extra" pins are not consistent a vary by manufacturer. I have to use one of these special break-out dongle's to get my laptop's tv-out to work.

hope that's useful. --scott

SOLVED!

Thanks alot all the people that responded,

After reading srahrens responce I began looking into the different connectors, and it turns out he was right, it was a problem with the adapter, however it works fine with my ati card in my windows box.

Thanks alot for all the help,
Neto
