    Hi, I have a dell u2713hm and at the moment my mbp mid-2010 15" can't display more than 1080p. I'm using mini-dp to dp and I used to get maximum resolution before. But this morning my computer froze in login screen and I restarted it. After that I only have 1080p.
    On my macbook air 2012 I can get max resolution by using the same cable.

    Is my gpu on my mbp dead?

    When looking in the system report it shows that the gpu is running the external display. Odd, it can't be dead then.

    Edit: Booted up in my backup drive and I could choose max resolution from there. Booted back up to main drive and had to switch between several resolution before I could choose max resolution. But it works now.
