Lost ability to choose 3440x1440 resolution

I have an LG 34UM95 connected via TB on a Late 2012 mac mini.


After the Yosemite install, I no longer have the option of choosing 3440x1440 resolution in the Displays preferences.


I did do the Option->Scaled bit to see the extended list of choices, but nothing higher than 2560x1080 shows up.


Can I get my 3440x1440 resolution back?

I have a MBP mid 2012, I don't have Mavericks from Time Machine, I just have El Capitan. I have the Dell U3415W, I can only get 3440x1440 @ 50Hz with the lid closed using a Mini DP to DP cable. If I open the lid I get this tearing at the bottom of the screen.

Note: I also have a MBP 17" from late 2011 and that display 3440x1440 @ 60hz using the same cable without a problem, so I'm thinking the issue is with the 13" Mac.

Is there a fix I can apply to the 13" MBP to get the full resolution @ 60Hz?
