    [SOLVED] DVI-I/D connected to a DVI-D to VGA adaptor.

    Hi mates I just bought a DVI-D to VGA adaptor and I just realized it might not work. I did not receive yet the item but I would like to know what others think about it.

    My PC graphics card has a DVI-D and DVI-I female input, I've got a only VGA screen, and bought a DVI-D to VGA adaptor:

    http://www.ebay.es/itm/DVI-D-to-VGA-...item20d94d3108

    but totally forgot if It would work since VGA is an analog signal and DVI-D is digital.

    Here comes the question:

    If I connect my DVI-D adaptor male to the DVI-I female graphics card input and the female entrance of my VGA adaptor with a male VGA cable to the screen, would it work.

    Here some info relating DVI cables:

    Plz comment Im pretty confused right now...maybe is just that Im tired after work and cant get to think this (surely obvious answer) right and thanks.

    Just did some research and found this very enlightening page: http://www.datapro.net/news/faq-how-...vi-to-vga.html

    Well, I had no idea there are so many types of DVI connectors ... I honestly didn't realise it wasn't so straight forward, not obvious at all. I thought the adapter itself would handle the conversion from digital to analog but apparently not.

    If you need a box like this http://www.datapro.net/products/hdmi...converter.html it might be better/cheaper to upgrade your monitor? (I'm guessing your current monitor is getting on in years?).

      Yeah, you can't convert DVI-D to VGA with a cheap passive adaptor. There are reasonably inexpensive active adaptors available though, such as: http://www.lindy.co.uk/cables-adapte...er-p7726/s7877

      However, you said that your graphics cards has both DVI-D and DVI-I sockets, right? Then you should be able to plug the cheap adaptor you have bought into the DVI-I socket, and that *should* work, because I think the eBay seller has simply labelled the product incorrectly, and that it is actually a DVI-I to VGA adaptor (it certainly looks like one in the picture).

        Thanks both for you'r quick replies.

        The link you gave me Rod J cleared a lot the path, It might actually work after all. I hope this works as a guide for anyone with the same issues around, It wasnt so straight forward as I thought in the beginning.

        Anyway not sure until I try I guess, so will reach you guys with some info after testing, meanwhile I will mark this as resolved.

        Cheers!
