I just built a new computer and plugged in my two monitors into my video card (GeForce GTX 770) which has one DVI-D and one DVI-I port each. Both of my monitors have VGA cables, so I used the DVI-I adapter I already had for my main monitor and that worked fine. However I just got my DVI-D adapter in the mail and it's not working. I tested 3 different monitors with it on two different computers and it wouldn't detect. The DVI-D port on my video card works fine, I plugged in a monitor that came with a DVI-D port already and it worked. I also plugged in the VGA monitor without the DVI-D into a VGA port on another computer and that also worked.

So is the adapter I got (DVI-D Dual Link) a dud or do my monitors just not take DVI-D or they can't run dual link? They both work fine with my DVI-I Single Link.

I'm pretty sure you can't get a DVI-D signal onto an analog monitor (unless there's maybe an expensive converter for it). With other digital signals like DP, you have to have an active adapter for VGA, so i'm assuming you'd need one of those. If that is what you have, i'd start googling around about your specific card, they all have little differences about what can be used at the same time and in what way.

The monitor that I'm trying to get to work with the DVI-D adapter has a spot on the actual monitor for both VGA and DVI-D. I don't really know anything about digital/analog compatibility. The monitor's cord is VGA on both ends, and I have VGA connecting to the monitor and the DVI-D adapter on the end going into my video card. I would try putting the DVI-D adapter on the monitor's end, but my video card doesn't have a VGA slot to plug the other side into, hence this entire problem. Ugh lol
