The laptop has a 7-pin S-Video port and I've been able to find the multiple display option in the graphics card properties, but it detects an HD TV, where my TV is non-HD. When I select the option to clone displays on laptop and TV, the display resolution goes down but nothing comes on the TV.

Any idea whether it is possible?

from what i understand, you are using a 7-pin S-video to composite cable to connect the Laptop to the TV.
First don't use clone mode but dual view and set the resolution of the TV from the nvidia control pannel to 704×576 or 704×480.

If that doesn't work, you can get a 4-pin S-video to composite cable as 4-pin S-video socket is backward compatible with 7-pin S-video socket. Using this cable will prevent your T.V being detected as HTDV.

please post a Scren Shot of you Nvidia Control Pannel settings.

It works for me.

I have a Dell Precision M70 laptop and have a 7-pin S-Video to single RCA connector cable (very short cable). I use a regular 3 connector RCA cable along with the short S-Video cable to connect my laptop to my 10 year old LG CRT TV. I then use Function (Fn)+F8 to select dual display on the laptop. The laptop automatically adjusts the resolution.

Whenever I play the Windows media player, only that gets transmitted to the TV (cool). At other times, you can see the entire desktop.

The graphics card in my laptop is nVidia Quadro FX Go1400 with 256 MB RAM.

@ntomer- Hey it just striked me that I too have a HP Pavilion laptop (DV 5200 series)

So mine should be 7 pin too

Fn-F8 does not work on my Dell Xps M1530 with NVIDIA 8600M GT
will try 7 pin cable instead of 4 pin

As far as i remember most of the models of LG Tvs come with S video Socket. ARe you sure you are connecting S video to RCS inputs & not to to the Svideo input?

Just confirming.

Its pretty simple if your laptop has a S-Video out. You need a S-Video to RCA cable. Both the 7 pin and 4 pin types are available. To find out which one is yours just count the number of holes on the S-Video out of your laptop

After connecting the cable, you need to press a combination of keys for the display on the laptop to switch modes. In case of HP/Compaq its the Fn + F4. You need to look for the sign above the F4 key as in the attached pic. Each time you press the combination, it switches the display modes. There are 3 modes usually..Only laptop, Laptop + TV and only TV. To get the best output on tv keep it in the " only TV " mode ( Videos dont show on the TV in the dual mode ). Get a stereo to RCA cable and you can now have the sound played from the TV aswell.

You cant shove a S-video connector into a RCA socket and vice versa.

LOL I know that Ajay

What I meant was that he is probably using S to S cable

My TV (LG) does not have any input other than the RCA connectors (AV1 & AV2). So it is getting connected via the yellow RCA connector. The 7-Pin S-Video to 1 RCA Connector had come along with the laptop itself (actually it came with the laptop of another colleague).

Ajay, do not underestimate our capabilities. I have had people make these kinds of impossible connections possible.

There is a separate cable S-video to 3 RCA, use that. it work like a charm. Using that from last 1 yr without any problem in my HP Pavilion

I had some interesting observations while hunting for S-Video to RCA connector cable.

Most of the cables you find are 4/7 pin S-Video to 3 RCA Connectors which are Component Video output (Y, Pb/Cb, Pr/Cr). So you would need "component video in" in the TV for this to work. So if you have this cable connected to the composite video in of the TV, it may not work. Some shopkeepers pass this cable off as having one RCA connector for video and the other two RCA connectors for audio which is not true.

I was not able to find 4/7 pin S-Video to 1 RCA conector for composite video in any of the shops. Most of the old TVs only have composite video in (yellow RCA connector)

All those having 4/7 pin S-Video out on their Laptops/ Desktops and only composite (yellow RCA) input in their TV's, just use this cable + a RCA male to male extension cable.

I have a XFX ATI Radeon 4350 1 GB DDR2 PCIe graphics card which works well with my old CRT monitor using a VGA cable. I tried using the SVideo cable and connected this to the TV from the S-Video out on the card. Yes, I got the picture, but there is no colour. I have fiddled around with all the settings in the catalyst centre as well as on the TV. Still no colour. Can someone help ? Has anyone done this ?

This is due to bad connection or bad cable. Since S-Video port is not used most of the time, it tends to get corrosion.

S Video carries color and luminance on different wires. If only luminance wires work, you will get B&W image.

Thank you. You could be right. There are 2 S-video inputs in the TV. I tried the first one which is at the back and this was the result, then i tried the one in the side and it actually showed colour, but the picture was on and off and blurry and jumpy, so i yanked it off and pushed it back again and i got pure B/W after that.
