    Hi,

    Can anyone answer this - I have a Z1 (which has a VGA input on the back) and will soon be getting a Denon 2910 which has a DVI port on the back. I was wondering if they could be connected using a DVI->VGA adaptor (like the ones that get thrown in free with a new PC graphics card) plugged into the 2910, and then connected to the projetcor with a standard VGA lead. Would this work - (the adaptor works fine converting DVI->VGA for my monitor on my PC). Has anyone tried this? And if so would it be better quality than using component leads?

    Cheers,

    Gromet

    I think you will find it does not work because the VGA in on your display is not HDCP compatable. You would be better off to use component.

    Sorry, but HDCP only applies to digital connections. :)

    There are two common types of DVI connectors:

    DVI-D, which is entirely digital
    DVI-I, which is digital and also analog

    With PC cards the DVI connector is usually DVI-I in which the analog pins carry the same signals as the VGA connector, the converter you mention simply maps those pins into a D-sub connector format, it doesn't actually 'convert' the signals from digital to analog.

    I don't know the 2910 so I can't be sure, but I'd have thought it unlikely its' DVI connector would be DVI-I and so will only be a digital output.

    As for PQ, RGB and Component are usually very similar, I think Component has a slight edge sometimes but it's very slight.
