    Well I have the physical connection sorted out, but regardless of the resolution I choose on the laptop I get the same message on the TV - "Picture format not available"

    What am I doing wrong?

    Check that your graphics card is set to 1024x768 at 60Hz. I'm guessing that the 60Hz bit is the most important.

    I tried all resolutions, which included 1024*768. I can only set 60hz anyway.

    Even tried rebooting the pc from cold...

    Is there a configuration within the TV set-up for this sort of thing?

    your trying the dvi - vga cable that come with it ? ~ have you confirmed you can output a external picture from your laptop ?
    try changing to a lower resolution and with that a higher refresh rate & ensure latest drivers are installed

    i'm looking at the same setup also for next year so am keen how you get on

    I am using VGA>VGA>adaptor>DVI

    It is a Dell Inspiron laptop. I have used other Dells in this manner, outputing to projectors, although I have not tried it with this particular one I can think of no reason why it would be different.

    Make physical connection and then hit Fn+F8, which normally toggles between 1 display (internal), then the other (TV or projector) then both simultaneously.

    When I hit the Fn+F8 keys I get the message mentioned above on the TV screen, so something is getting through.

    I tried all available resolution options. I only have 60Hz refresh rate option available on the laptop. I wonder whether this the problem?

    Using Windows XP SP2, if that makes any difference.

    so long as the laptop is tested as output to another external screen, then i suggest borrowing someone's VGA-DVI interface are upping the refresh rate or horizontal scan rate

    have you checked both modes of the inspron, i.e. External + Internal, & External only ?

    ..a have look at other threads as they seem to get PC-DVI to work ok

    2 more things, for my own planned setup, can you post a pcture of the connectors, i can't find on anywhere on the internet
    lastly...how have you connected ta AV source to it ?

    thx

    your best off using a VGA port if your telly has one, or the TV out (svhs) on the laptop.
    vga->DVI which your basicly doing works only some times without any headaches.
