Ugee Monitor tablet Offset

I downloaded the free trial of ToonBoom, hoping to get a good feel before buying, and it seems there is an offset problem, no matter how much i try to resize my display settings, or calibrating my monitor tablet, i can’t find the reason. It works just find with my photoshop cc and tvpaint. The distance from my pen to the courser doesn’t stay linear. So it feels like a display problem.
