    Hey :)

    I have mac mini late 2012 running on 10.8.5 and a LG 34UC98 screen connected through thunderbolt.
    It has been running perfectly smooth with 50hz and in full resolution (3440x1440px).

    After an update to the latest macOS elCapitan (10.11.6) I cannot get it working... it is only working in reduced resolution (2560x1080), which is very bad. As soon as I switch to the full resolution, I see a lot of pixel errors (same as here: https://discussions.apple.com/servl...mage/2-25833361-427367/450-188/screenshot.jpg).
    Also, I found this topic at apple (https://discussions.apple.com/thread/6240037?start=0&tstart=0), but patching the kext did not work - no changes...

    Any help is appreciated - it would be great to have this nice screen working again in el Capitan!

    Thanks guys!

    You could always consider "going back" to 10.8.5.

    Yeah, I'd love to, but not possible ;) ...as I have to be in sync with a brandnew mbp and an iMac which run at el Capitan, that's not doable...
