Hi, I connected successfully my 2560x1600 monitor that has only a DVI-D dual link port. I bought a startech.com adapert that is ACTIVE because I wanted to connect it to the docking, but the docking is problematic for some set up, so didn't worked was flickering. So I connected it to the Sp3 mini displayport and it work perfectly. But, I've read many times in this forum that to the Sp3 device it is possible to use even a passive cable! Is it true? so could I try to connect my monitor with a simple mdp to dvi-d passive cable? please clarify, if it is true and correct and if I will not have some issue for some reason, I repeat I need to connect a 2560x1600 monitor, so I hope to have some feedback from who did it with a dvi-d dual monitor and not a lower resolution. If possible, I will have 1 usb port again free (the active adapter need it!) thanks!
