    iMac on TV - HDMI vs. 3-RCA cable

    sorry if this was answered somewhere else, but my searches didn't bring anyghing up...

    I want to bring my iMac Screen on the TV.

    There are different ways to that: first, via VGA-calbe, then 3-RCA-component-cable, then HDMI cable.

    I tried two of them myself: HDMI and VGA-cable.
    HDMI works fine, I can use the TV as second monitor and run my monitor and the TV with different resolutions. Great.
    VGA just lets me see a copy on the TV and the resolution is less.

    So, did anyone try this via 3-RCA cable? I don't want to buy and return the third set of cables and adapters...

    My question would be: can I use different resolutions there or not? That's the most important issue for me.

    Thanks for any help here!

    Texas, where else?

    The quick answer is No. The $5-$10 VGA to component adapter cables will not work.

    It will require a converter box. The converter boxes under $100 have extremely limited output resolutions and would likely require a converter in the $250 range to do what you want and would likely offer nothing you're not already getting via HDMI.

    A better question would state what it is you are actually wanting to do along with the info requested here.
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.
