Hi all,
I share the experience told by Jimmymck. Following the advice by ozbody I bought a miniDP to DP cable from CircuitsAssembly to connect my 2009 MBP to the brand new Dell U2711. It was amazing how with just this cable, I could reach the maximum resolution at 2560x1440. However, it was like that for just a couple of months. Then, suddenly, one day it did not work any longer. I couldn't get any output from the MBP to the monitor. I complained to Dell who promptly sent me a new monitor. Happy for a while! It took another couple of months the new monitor to suffer from the same weakness. I'm really afraid this can happen again, for the third time.
The mini display port of my MBP is, apparently, working perfectly, since it does work ok with miniDP to VGA or miniDP to DVI, even with a miniDP dual link DVI.
By the way, when using the dual link DVI adapter, quite often the image gets an annoying fog which can only be removed by switching off-on the monitor or unpluging-repluging the adapter. Any other experiences in this line?
I would thank further notice about more this issues with the Dell U2711. I suppose the company should study in depth this and provide us a solution.
I am having this problem as well. I too purchased the Dell U2711 and a mini display to display cable as per the advice of CircuitsAssembly.com to connect a Macbook pro. I was amazed at the easy setup and full resolution this method offered. However, last night I did not shut down my Macbook Pro but I turned the U2711 screen off. This morning I awoke the Macbook Pro from sleep and turned the screen on and nothing happened. The screen works with the DVI cable to my PC but does not work with the Macbook via the mini display to display cable.
I have tried everything suggested on the forums including deleting the cache and resetting performance etc... through Onyx to no avail.
The funny thing is, when I plug the Macbook into the U2711 screen the Macbook display will flicker like it did when it was working but the U2711 screen fails to switch on. Detect display offers no help or information (very annoying).
$4000 of hardware... I have read so many problems relating to the compatibility and bugs of Macbook Pro connections to external monitors however it seems this may be a Dell problem but the sleep thing does concern me. Very upset. Will be contacting Dell on Monday.
