    Hi guys!

    I just got from a friend a huge 52 inch back projection CRT TV. Since it's old, it comes with no HMDI or any other kind of digital input.

    I was wondering if I can simply use a cable (with no box converter in the middle) to connect my Mac's mini-DVI to the TV via 3RCA (composite) cable or component cable?

    The mini-DVI port sends analog, digital or both signals?

    I have here with me a mini-DVI to HDMI converter from Apple and I was hopping to just get a HDMI to 3RCA (composite) cable or component, which would carry an analog signal to the TV.


    Thank for the help. Cheers!

    Maybe this can help:


    PS: You have a Mini DisplayPort not a Mini DVI port. And Composite is a yellow RCA plug, 3 RCA plugs are either Composite (yellow) and stereo analog audio (black/white and red) or Component (green, blue, red).

    Thought it was a mini-DVI. But now I know the difference. Thank you.

    What I'm not getting is if this MDP sends analog or digital signal?

    If it sends analog, then a simple cable that converts the connections from HDMI to 5 RCA would do it, right?

    See the first, big link on how to use MDP and Composite or Component. And what is it, 3 RCA or 5 RCA? Anyway, the first big link shows you what to use, and yes, MDP can send analog and digital signals, but there is no MDP to RCA adapter as far as I know, only a quite expensive one I found on Amazon via "mdp to composite".

    Ah I saw it now! Thanks!

    So for a unibody macbook I need a MDP to VGA adapter (which Apple doesn't sell anymore apparently) and then a VGA to 5 RCA adapter. Right?

    Then for the audio I can user a 3.5mm jack to RCA.

    For the audio you are correct, for the video too, you can get an MDP to VGA adapter via Monoprice (first quote in post #2). As I still do not know, what you mean with 3 RCA or 5 RCA, I cannot help you there. Do you know, if you have Component or Composite?

    3RCA is composite and 5RCA is component.

    I am still not sure if the TV has component but I do think it has. Since that's the best connection for a better quality I will take that one.


    OK.

    Then its simple:

    For video: MDP -> VGA + VGA -> Component
    For audio: 3.5mm jack -> RCA


    Since this is an old TV, it has no digital inputs. But I guess with this setup it will all be analog signals and should work fine.


    Thanks!!

    I do not have the TV with me yet, maybe later today or tomorrow.

    I'll let you know. Thanks!

    Those adapters seem to be the correct ones, MDP to VGA and VGA to Component.

    I haven't picked up the TV yet (will do tonight) but I got a photo from the back.

    This is a Component connection, correct?

    Yep, that is Component and stereo audio.

    I skipped the 52'' FAT TV. It was way too big, wouldn't fit in my car.

    So I won't be needing this cable arrangement.

    Although I have another question since I just picked up a Sharp Aquos 42'' LCD for a very nice price.

    One of the HDMI ports on the back has a 3.5mm sound socket. Is this an audio in? A 3.5mm cable M/M will be enough to bring sound from my MacBook to the LCD?


    EDIT: And is it possible to have a full screen movie playing on the LCD and still be able to use the MacBook screen for something else? Because when I enter full screen on the LCD, my MacBook display turns black.
