Hi, thanks for sharing your experience with this monitor.
I did some reading and for me to get the native resolution (2560x1400) on the 2711 monitor with the Macbook Pro, I need to use a minidisplay port (which connect to the macboo's new thunderbolt slot) - displayport cable. Lile you said, not all cables will give you high res. Most of them (HDMI,DVI) only give max 1920x1200 There wasn't many places in Oz selling these cables either but I got one from Macfixit in Melbourne. The
Dell 2711 is getting delivered tomorrow and hopefully my new mackbook pro next week....will post up my impression.
