Hi - I have a new U2415 that I am not getting a signal on when I plug it into my desktop using a Display Port to DVI adapter. This is an Active adapter I bought from Amazon; I have the adapter plugged it into the Display Port IN port and then the DVI cable going to my PC. When I try to "detect" for the monitor in Displays under Windows 7 64bit I don't see it in there. I have 3 other monitors plugged into my PC using a Quad Port ATI video card (ALL DVI) and I know all the ports work as I have switched them around.
When I plug the monitor into my Mack Book using the Display port cable that came with it the monitor works fine. I also know the DVI cable works fine as I have tried this on another monitor.
I have also tried a mDP to DVI using another adapter and this also doesn't work.
I have also downloaded the Dell Display Manager software but it gives an error saying it needs a supported Dell Monitor.
Any ideas on why the Display port to DVI is not working? Can anyone suggest any other ideas. I'd like to keep my current quad port DVI Video card as these are expensive to change out.
Thanks much
