Connecting Macbook to LG HDTV (RZ 32LZ55

[harryhog]

I've recently bought a Macbook and have tried connecting to my LG HDTV. I previously connected a normal PC laptop using a VGA (at computuer) to DVI connection (on TV).

I bought the macbook mini-DVI to vga connection to connect to the end of the existing cable. So...from laptop-tv connections were mini-div to vga, vga to dvi. This doesn't work, the tv doesn't even go to DPM mode.

There is another connection into the TV which is called RS 232C, but i've no idea what this is for.

Does anyone know how I can connect to this TV???

Thanks for your help,
Harry
