    Mac book to TV problem
    hello,
    I recently purchased a mini DVI to VGA and a composite cable to connect my mac book to my older tv, but no display arrangement tab appears on my mackook screen when connected. My tv does not display the macbook screen either. I clicked on apple-->system preferences-->display and clicked on detect display, but it does not detect my tv and there is no arrangement tab or mirror display either.
    My tv is pretty old and only the 3 red, yellow and white outputs in the back.
    Does anyone know anything about this problem?

    What kind of TV, make, model?

    I'm assuming you're using the Apple mini DVI to VGA adapter, and then a VGA cable from the adapter which terminates in composite video (R W Y) to the TV input?

    If the TV has a selectable menu for inputs, make sure that you have selected the R W Y composite input for a video source. Some older TV sets won't display nor are recognized by a computer. Not just by an Apple MacBook but also PCs.

    Regards.

    Your set-up is like mine, macbook to old composite video TV

    you need an extra box to convert the signal to analogue like this one

    Yes, I got mine from a dealer in China (good rep on ebay). it works, kinda difficult to navigate around on my lores TV, but plays movies and the BBC iPlayer fine on my Macbook.

    Easy to set up, only had to adjust a jumper switch to sync the macbook to the TV.

    Set up is, mini DVI to vga connects to the box. The box connects one yellow video phono plug to the TV for the picture. The box gets its power from the macbook via usb. I connect the sound separately, using 3.5mm audio jack to 2 phono stereo jacks.

    Good to know, thanks. Don't believe I've used composite since S-Video came out.

    Hi everyone,
    my TV set is a Philips 13PT30L 13".
    and yes I am using the Apple mini DVI to VGA adapter, and then a VGA cable from the adapter which terminates in composite video (R W Y) to the TV input.
    I checked the different external sources on my tv (AV,EXT,GAM,DVD,VCD,VCR,LD) but none seems to work.
    I was wondering if there is a particular resolution that is appropriate?
    I will try the video converter box. can you get it at radio shack?
    Thanks for your help.
