So I have a 2560x1440 Monitor made by shiman/yamasaki (two actually). Also, I have two Active Mini Displayport to Dual link DVI adapters one by apple one by startech. It doesn't seem to matter what combo of dual link cables and adapters i run i just cant run a dual link display. My 1920x1080 monitors work fine obviously they are single link. I am running the latest beta drivers for the 660m. Has anyone had this issue or know how to fix it? Maybe its just the active adapter?
