We have identified an incompatibility with the DTU-1031AX and the Open on Display function in our sign pro PDF application (v4.x).
Symptom: It doesn’t size the window opened on the display correctly due to the smaller resolution.
Resolution: This specific feature does not work with the DTU-1031AX due to its smaller resolution. We would recommend using a compatible Wacom for Business device with higher resolution or explore other options with the Wacom for Business group.
