S Cable - Connecting laptop to tv monitor

rrcn · September 4th, 2004, 09:59 PM

currykarpal, what kind of "black plug" is it? S-video? There are all sorts of black plugs it can be.

Can you take a picture of the plug and the port it plugs into?

Hi Everybody,

Googling and searching the discussion boards on connecting my laptop(Compaq Presario 2182US) to Apex Tv with S Video to RCA Adapter, I was finally able to get the display of my laptop to TV. I have scratched my head for hours to get this.Everything I did seemed to be right except that it was not working. Here is what happened.

After making the connections (S video of laptop to RCA of TV with an "S video to RCA Adapter") I hit Fn + F5 on laptop, my laptop screen would flicker for a second and I see nothing on TV. Later I connected the RCA cable to video port of my VCR I was able to switch the display from my laptop as I could see a blank screen on laptop when I hit Fn + F5. Then I unplugged the cable from VCR & connected the RCA cable to Video port of TV and was able to get the display. I still have to do this every time I want to connect my laptop to TV.

I do not know exact technical deal behind this but my guess is my TV is not giving some hand shake signals to laptop which recognizes it as an external display. I came to this conclusion as the same laptop works fine without changing any settings when i connected to my friends sony tv.

Hope this helps & saves some time for others who are facing similar kind of problems.

Thanks for all your help

hi, rvbabu

Not sure what the problem is as you are getting a display? it sounds as if you haven't checked the cycle present in the display switching,

but i tend to sort everything out in display properties first.

Also, there is no 'handshake' present with Svideo (unlike USB for example) as the picture info only travels one way. It is more a case of setting the PC up to send and then having the TV on the correct channel.

Oh and Black and white images are to do with PAL (europe) and NTSC (USA) design - there is lots of info kicking about on this subject. http://www.videohelp.com is always a first port of call.

Any more Qus i'll see what i can do.

S-Video is composed of two signals, a chrominance (color) signal and a luminance (brightness) signal. If the chrominance signal is missing, you will get a "black and white" picture.

Check your laptop's video out settings and make sure you are outputting S-Video and not composite video.

You may also have a bad cable.

I have the same exact problem! Did you find a solution? I have checked all display settings. I used a Dell to connect...and that worked! Obviously it's an HP issue...not an s-video or Samsung issue!

Glad to hear you got it fixed. For the benefit of others, could you post a quick explanation of what you did? Was it in your display properties?
