I am trying to send the video signal from my desktop computer to HD LCD TV.
The only video port on the desktop is VGA.
The TV has S, RCA (composite and component) and HDMI input.
So I bought on ebay the VGA to S, RCA adapter shown here:
From there I used S-video cable and pluged into TV.
Nothing coming out.
I read somwhere that this can work only if the video card has TV-out capability.
I believe (but not 100 % sure) that my video card Intel® 82945G Express Chipset does not have TV-out based on this link .
Could somebody let me know is it true that my video card has no TV-out?
If so, what option(s) I have to get the video signal from my desktop computer sent to the TV?
Thank you

If you have an open hdmi port you could do part of what I am doing - I have dvi out on my graphics card and I use a dvi-hdmi cable. In your case you will need to use a vga-dvi adapter first and then purchase a dvi-hmdi cable. THat way you will go from vga-dvi-hdmi. Not the best route but if you don't have a vga nor a dvi input on your hdtv than this is the best option I belive you have. If you go this way then you won't have to worry about tv out since it will take a digital signal and put it on the tv.
Make sure you don't have a vga port on your hdtv first. If you do have one than simply buy a plain vga cable that will connect to both the graphics card and tv.

There are only a few video devices that output an S-Video on unused VGA pins. None of the well known display chipsets do this. S-Video is usually found on the 1234 pins of a "TV-Out" connector. These connectors have 4, 7, or pins. Sometimes (e.g. NVidia) the extra pins carry YPbPr analog component.
In your case, you will need a different display card for your desktop that has S-Video (for SD) or analog component (for HD) or a DVI-I that can be connected to the HDMI port.

Thank you all for the replies.
As I do not wish to change my video card, I will then have to go with this vga-dvi-hdmi option for the LCD TV.
My quick search on google for vga to dvi adapter gave two different things:

and
[img]http://forum.videohelp.com/images/guides/p1805790/ http://ecx.images-amazon.com/images/I/318PNYZDP0L._AA280_.jpg [/img]
but I believe it is the first one that you were having in mind, otherwise please let me know.
I also have a second TV which is analog and has only composite RCA input. What is my option in that case (without changing the video card).
Thanks.

The VGA->DVI->HDMI cable option will not work. DVI has the option of carrying analog video. HDMI does not. The analog pins at the DVI end of the DVI->HDMI cable won't be connected to anything at the HDMI end.
A $50 graphics card will get you DVI output (with which you can use a simple DVI->HDMI cable) and better performance than your integrated graphics. This is a far better option than an active VGA->DVI converter for >$200. You can even get a graphics card with an HDMI output for not much more:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814127301
That particular card even has the option to accept digital audio from the computer and route it to the TV via HDMI.

Yep forget the cable. That is intended for the other direction DVI-I to VGA. DVI-I carries pins for DVI-D (digital) and VGA (analog RGB).

A converter box is both more expensive and lower picture quality than a new card.

Ok, it's more clear now, with such difference in price, a new graphic card seems to be inevitable to have video on my LCD TV.
As for my analog TV with the RCA input only, what do I need to get computer video to it?
Thanks a lot

Anything with S-Video out can use a summing adapter or cable to sum Y+C to composite.

Hi,
I am actually facing same problem with the owner of this topic,
I have a labtop, sony vaio with winXP sp2, Geforce ge 6200 as
my video card I bought the exact same cable believing that it
would work on my VGA output, seem like nothing coming out
so far, I believe that my card have a tv-output capability, but
I'm really not sure how can I connect it to my TV, (i have
tried connected s-video cable and check in the display properties
to find the TV option but there're none)
Am I in the right track?
Thank you so much for your answer.

Yes. Turn off the TV and laptop. Plug the s-video cable into both devices. Turn on the TV. Then turn on the laptop. The computer should detect the TV and enable the s-video port. Go to the graphics card's setup applet and see if any TV options show up.

I've never seen anything but VGA RGBHV come out of a laptop VGA port. The "TV-Port" can offer S-Video plus many proprietary alternatives depending on display chipset and laptop maker implementation. Pins 1-4 get you S-Video (Y/C). Other pins are non-standard. A 7pin connector may add composite and maybe audio. A 9 pin connector may add PbPr (you already have Y). Most of these work through a dongle that may have been suppied with the laptop or is available as an option from the laptop manufacturer.

I have read all the previous postings in regards to obtaining a signal for tv output. However, I am not using a deskop but a laptop that only has vga output. I went about the same route and purchased that "dongle" that has vga to s-video and it does not work. Do I have any other options to covert the vga to s-video signal that will actually work? I'm running a presario 2200 laptop. Thanks!!!- joe

An external scan converter: http://search.cablestogo.com/Search.aspx?qu=vga+converter
Does your laptop have a PC Card slot? Maybe a PC Card video card?

You won't be happy with S-Video quality. Check another computer's S-video out and accept that scan converted will be even worse. I'd still invest that money in a new HDTV fund. For $160, you could even get a quality 19" LCD computer monitor (DVI-D + VGA) that would look far better.

Yes, s-video will give you a resolution of roughly 640x480 (NTSC) or 640x576 (PAL). If you are running your desktop at 1024x768 (or whatever) it will be downsized to roughly those resolutions before being sent to the TV. Windows isn't usable (normal sized text is barely readable) this way. It's OK for watching DVD or dowloaded videos. Here's a rough simulation of what a 1024x768 desktop will look like via s-video:
On a TV it will be bigger but just as blurry.

Well here is my situation... I have video software on my laptop that I want to run to play music videos, display graphics, photo montages, etc.. The output will be displayed on plasma screens. This is what I am trying to do. I will not be using any text and always run the program in fullscreen mode.. Would the s-video scan converted signal be appropriate for this considering I'm not going to be using it for small text?

S-video will work. Your high resolution photos will not be sharp like when viewing them on a computer monitor. You won't be taking advantage of the high resolution the plasma TV is capable of. It will be like watching standard definition TV on the Plasma TV (a little to a lot worse because of the multiple scalings and quality of the scan converter).
If your digital camera/camcorder has composite or s-video TV output try hooking that up to your TV to get a rough idea of what you will get with a scan converter. Or convert some of your photos to standard movie DVD and watch from a DVD player via composite or s-video. Many DVD players will even display JPG images from a disc.
