Sad about the display. The rubberband-trick is for the Pro1X not the Pro1.
If you got a Pro1X things is a bit more complex getting the full touch area of the display. The only way to initialize it properly is attaching it to a Pro1 (not Pro1X) first, and do a reflash of that (there should be a lengthy step by step guide if you follow the links in the first pinned post in here). The reinitialisation of a Pro1 includes a step that setup the display correctly, and sadly no one has found a way to isolate this code so it can run on a Pro1X...
