Sorry I don't follow... I run Minion from low to really high (4k & retina) resolution and it scales just fine? Whats the issue you are having? The UI is all vectorized so even in Retina it looks nice and sharp.
Here it is 2880 × 1800 (retina)

I can post a pic from my win10 2560 x 1600 display too.
Can you post a screenshot of your issue? What resolution & DPI are you running?
