since OS X 10.8.4 Mountain Lion update and now also Maverick update, I can no longer select the 2560x1440 resolution to my

external Dell U2711 display. 1080p is the highest availible resolution now.


I have a 15" Macbook pro retina 2012 and use a mini displayport to displayport cable to connect to my Dell U2711 display.


Is it a cable issue or what is the problem?    (the cable worked great with full 2560x1440 resolution up until 10.8.4)



Best regards



MacBook Pro with Retina display, OS X Mavericks (10.9)
