    Hi All

    I am buying an HTPC that only has 2xDVI out, but it apparently comes with a DVI to VGA cable.

    I need to run VGA to my Sony HS50 projector as it is generally regarded as the best connection even over DVI.

    My question is whether the DVI > VGA cable converts the digital signal to a normal analgoue one that the VGA cable can carry, and whether there would be any difference vs just a VGA out?

    Thanks

    It will work exactly the same as a standard analogue VGA output.

    The digital to analogue conversion is done on the GFX card, it just remaps some of the DVI pins to the same function as a 15 way D-sub socket. The DVI to VGA 'dongles' are just straight through connectors.

    DVI comes in 3 versions:

    DVI-A - analogue output only. It is just VGA through a DVI connection.
    DVI-D - digital output only. No VGA output is available, even via the converter you mention.
    DVI-I - this carries both analogue and digital.

    AFAIK the output from a graphics card is DVI-I and therefore to connect to a standard VGA monitor etc you just need the converter.

    Mark.
