    Laptop TV-OUT VGA - TV Not Picking up Signal


    Hi,

    I'm trying to connect a TV to my laptop and want to use my TV as the second monitor.

    I'm using a brand new VGA cable and the laptop is picking up the TV fine, I can change resolutions, extend etc but the TV just says 'No Signal Through PC'. I'm not ruling out that I've been unlucky enough to buy a dodgy VGA cable but I don't have another to test it with here.

    Could there be anything I'm missing?

    Why don't you try HDMI ?

    Simple reason of already having the port taken up by something else. I don't want to be forever swapping cables.

    How do I connect my laptop to my TV with S-
    Video?
    The S-Video port is found on most laptops with TV-out
    functions, and can connect your laptop to both analogue
    and digital TVs.
    It doesn't provide High Definition (HD) quality, and
    only carries the video signal, so you'll also need to hook
    up a separate audio cable - typically from your laptop's
    3.5mm headphone jack - to the audio inputs on your TV.
    Your TV will need one of two things: either separate S-
    Video and phono audio ports, typically found on the
    front of the TV, or a SCART socket found on the back.
    You'll then need to purchase an S-Video cable of
    suitable length such as this 2m cable, along with a
    suitable audio cable. If necessary, you can then
    purchase a SCART adapter to connect the cables to
    your TV.
    DOUBLE UP:You'll need two cables - one for audio and
    one for video - if connecting via S-Video

    Thanks for the help but I need more specific troubleshooting help. I've connect everything up via cables, I've set up the second screen for the right resolution - the TV just won't pick it up.#

    I'm guessing faulty cable but have nothing else to test it with.

    HOW

    Check your computer's available output ports.
    There are 4 main types of cables you can use to
    transmit a video signal from your computer to your
    TV. These are HDMI, DVI, VGA, and S-Video. If
    you are unsure of what each port on your computer
    is, you can consult the owner's manual or look up
    photos of these different cables online.
    Determine the available input ports on your TV.
    You will also be constrained by the types of video
    inputs your TV can handle. Check your television
    for the same 4 cable types listed above. The
    newer your TV is, the more likely you are to find
    these options available to you.
    Determine which ports are shared by both your
    computer and TV . Of the 4 types of cables,
    ideally at least 1 type of port will be present on
    both your TV and computer.
    If there is only 1 shared type of port, then that
    is the best way to connect your TV and
    computer. Purchase the appropriate cable type
    at an electronics store.
    If there are multiple ways you can connect your
    TV and computer, determine which is best.
    HDMI should be preferred, because it can
    handle both high-quality video and audio. DVI is
    the next best cable type, followed by S-Video
    and VGA, which should be avoided if possible.
    Pursue a different connection solution if
    necessary . If you cannot use 1 of the 4 cables
    mentioned above, there are other options. You can
    search for an adapter that converts 1 type of the
    above signals to another.
    Another option is sending a signal to your TV
    through a USB cable; for example, a cable with a
    USB plug on 1 end and RCA plugs on the other
    will be usable with almost any TV and computer
    combination.
    Note that solutions involving USB cables will
    almost certainly be unsuitable for video gaming
    or other applications that require a fast frame
    rate, no delay, and a lot of processing power.
    These cables will be fine for photo slideshows
    and classroom presentations, however.
    Set your TV to receive the computer's input.
    Generally, this is done by setting the TV to a
    certain channel or by cycling through its "input" or
    "auxiliary" channels. After connecting the 2
    devices using the appropriate cable and booting
    your computer, find the required channel on your
    TV to display the computer's output.
    Send the audio signal to your TV if desired. Of
    the 4 cables mentioned above, only HDMI carries
    both a video and audio signal. If you want your
    computer's sound to be played through the TV's
    speakers, you will need to send the audio signal as
    well. The easiest way to do this is by using a 3.5
    mm cable (which connects to your computer's
    headphone jack) with RCA plugs on the other end
