Hello, I have a Macbook Pro 2.4 gigahertz laptop. I recently bought a VGA > RCA conversion cord to use with the DVI > VGA converter that came with the macbook. I am trying to mirror my display on to my LCD TV using the RCA hook in's. I have tried all the different resolutions and refresh rates and the best I can get is like the screen is black and grey lines moving up and down and a weird noise coming from my TV. I'm assuming it has something to do with the refresh rate, the lowest I can get it at is 60 Hz on mac. I know its possible to work because when I restart in to windows and mirror the display it works fine. I think in windows I am using a 50 Hz refresh rate. Is it possible for me to get a lower then 60 Hz refresh rate in Mac OS X? or is there something else I need to do?
