    Video to TV (XP Home SP2)

    I hope this is the right forum for this question. I just got a new LCD TV and want it to display photos from my Notebook. When I connected the two via an s-video cable the TV showed my Windows screen in black and white! The s-video cable is OK because it works fine between the cable box and TV. Any idea where I start to debug this? Would I have better luck using the VGA connection?

    You have to connect your computer to VGA input for use your TV as a computer or game monitor.

    Use composite (RCA), or better, DVI or HDMI inputs to connect cable box, satellite box, DVD player and VHS recorder to your TV. Use F-type (75-ohm cable) input only if you have no other choice. Avoid to use s-video input - it is outdated and can be used only for legacy devices.

    I too have a similar issue with my video card.
    After getting a LCD HD tv I installed a second video card with vga, video out and S-video out, as there is an occasional need for a large screen for video editing. It was an older card that I had in the component box.
    The vga output to the TV is the best. Video out to the TV is not as sharp an image. S-video out to the TV is black and white and fuzzy.
    You should stick with vga. You can acquire a simple vga splitter duplicate the monitor screen on the TV.
    Of course if you update to a second or replacement video card, one with DVI or HDMI would be preferred.

    This is a 4-yr old notebook, with video on the motherboard. It has both s-video and VGA output connectors. I tried the s-video because I had a spare cable available. I will get a VGA cable at my local CompUSA. I'm still curious why the s-video appears in black and white on the TV, since s-video supports color.

    The only reference I found concerning the black and white condition can be found at:

    The reason that you are only getting a B&W picture is because the adapter that you are using is only connecting the luminence, and not the chrominance.

    Thanks for the info and the link. I'm still puzzled. My TV is new, with an s-video input connector. When you say the "adapter" do you mean the s-video cable, or the s-video output from the laptop? The cable is fine, as stated in my original post, because I can connect it between TV and Comcast cable box and get color TV.
    Can the laptop put out an s-video signal without the chrominance? Possible, but hard to believe.

    From http://www.epanorama.net/circuits/svideo2cvideo.html :

    "A typical problem that causes black and white video instead of color is incomatible video standards on the signal source and the receiver."

    For example, see 7 Pin S-Video Pinout and Apple S-Video Pinout.
    Take a look at 4-pin s-video pinout also.

    Problem solved. Got a VGA cable and my photos look great on the LCD. Interesting discovery. My laptop has both a VGA and s-video outputs. When I went into video display properties/advanced I found three options for displays: Monitor, Panel, TV , each of which must be enabled to work. It turns out that TV refers to s-video and should not be enabled. Monitor (as in external monitor) refers to VGA, , and must be enabled to communicate with the TV. I just love the techie terminology!
    As for the s-video, there was certainly a mismatch between the PC and TV connectors, as kaplinb suggested.
    Thanks to all for your comments and suggestions.
