good impression is marred

The docking station makes a very good-quality and overall impression. Material and sockets are fit, the housing has no play and is a unit with its inner workings and its base plate. Since nothing wobbles. Toll. Unfortunately, the good overall impression is marred by a clearly perceptible delay in the display on the connected display. At the beginning I had the impression that only the mouse control would run slow. Then a delayed image rendering showed. I was the disturbed enormously. Maybe it's just a single case, which is attributable to the individual components. I can not tell. As a precaution, the product goes back therefore. Too bad.
