3. How to configure the UPDD Zoom and gestures The latest version of UPDD is configured to use Zoom Screen with the 2 finger tap gesture. Zoom Screen zooms only within the controller's display. The Smart Magnifier zooms outside the controller display as well. If you need to change the behavior of the Smart Magnifier here are the steps to do so. If the Smart Magnifier shows the desktop instead of zooming on the MP Host plugin see  here First make sure you have the latest UPDD version installed. This should be normally obtained from   Touch Base . Allow   the necessary access on Mac OS. Open the UPDD Commander Settings  from the top bar on the Mac                                   Go to Smart Magnifier tab and set the: Width to 1920 Height to 1020 Rectangular Shape and to Not follow touches     5.
