I got this mini displayport to dual link DVI adapter to make it work, with flaws, flicking screen when background is dark black, google it, found many complains about it. If I simply use the included HDMI->DVI adapter, I got 1280x800 only. I am really confused, I was thinking it should at least gets 1920x1200 if 2560x1600 isn't supported. Now don't know what to, any tricks you can share? Thanks a lot.
