I am experiencing an issue with the macbook pro retina and an external display HPw2207h, I use the HDMI port.
The native resolution of this screen is 1680x1050, but I can't use it on this resolution, it seems that every other works fine.
When I use 1680x1050, the screen flickers, I see the image of my wallpaper for half a second, then it gets black and it continues like that again and again.
Thanks for any help
I have exactly the same problem.
But since I download the las update, everitime i conect it both displays just turn black and i just see the mouse's pointer.
