    Not sure this is the right forum but here goes.

    I have a monitor with only a DVI-D(male) connection.

    I have a laptop and other AV equipment with a VGA out(female).

    I want to view the content on my monitor.

    I have bought a DVI/VGA adapter but when I plug it in nothing appears on my monitor. The adapter has a VGA male and a DVI female.

    Am I using the wrong adapter or is it a broken adapter?

    Please help!

    That converstion is not possible. Going from VGA, an analogue signal, to DVI, a digital signal, is not possible without an expensive digital to analogue converter, which probably doesn't even exist as buying a new graphics card would be far cheaper than any converter someone could make.

    The only reason that you can connect a VGA display to a DVI port is that the DVI out ports often have the analogue VGA signals on a dedicated set of pins. If your monitor doesn't accept that set of pins on the connector there is nothing you can do about it.

    These adapters actually DO exist, but they're very expensive, typically in the $300-400 range. They have to convert and scale analog RGB signals into digital TMDS signals. Gefen makes one if you really want to connect it that badly.
