I have LG 27MB85Z as a 2nd screen with my late 2013 iMac 27, connected via thunderbolt. Using native resolution 2560 x 1440 same as iMac.

Displays picture is soft/blurry. Displays menus are crisp and clean so it's not panel fault, especially 'cause display has been working just fine before in OSX 10.8. Same set up and connected via thunderbolt.

There were same issue at first time connected the display, soft picture but got fixed by Force RGB patch ( if I remember correctly ).

Now, after updating to Yosemite ( OSX 10.10 ), problem is back. This time Force RGB patch doesn't fix the problem, display is still soft/blurry.

Anyone with a solution for fixing this ?
