Outstanding
With Yosemite, the 1920x1080 screen option in settings/display disappeared. I spent (I am ashamed to say) half a day trying to properly configure my non-Apple second monitor after installing Yosemite, and couldn’t get it just right. This little app fixed the problem in seconds and my screen looks better than ever. The app does exactly what it promises, and more.
