mini dvi output issues.

Posted:
in Current Mac Hardware edited January 2014
I have a macbook 2.4gb intel. i am running the latest version of leopard. I seem to be having trouble with my dvi output.



when i plug in the converter, the mac recognizes it and readjusts the screen



on the tv, (my older read projection) ,all i see is grey squiggly lines, not snow.. the picture is there but it is not converted properly. i cant see anything. i press command f1 and something usually happens and goes back to the grey shit.



i try it on my hd tv, and it just says /'no signal/', so i am assuming that the picture isnt getting converted properly. could it be my converter, or is it something in the output setting or the mini divi port? the converter i got was one from best buy- dynex, and it has a mini dvi male, and a female composite and s-video.



any ideas?

    Check your MB video settings. Are you using PAL or NTSC? 50 or 60 Hz? (Your description sounds like the it's a frequency issue.) What is your resolution? Are you interlaced or progressive? NTSC composite and s-video is 60Hz 480i.

    From the description of your computer, I'm guessing that you have the early 2009 MacBook with NVIDIA chipset and 9400M graphics. That computer only supports DVI, dual-link DVI, and VGA graphics outputs via an "adapter". It doesn't support composite or S-video unlike some other Macs with Intel or ATI graphics. However, it's possible to buy a true converter to do that job but I believe what you have is an adapter, not a converter.



    Doesn't solve your problem but at least should keep you from thinking you're doing something wrong.
