Same issue as Sam. Pressing the screen while powering up and releasing shows the calibration screen with red markers in every corner. One corner has a white marker, touching it shifts the marker to the next corner but now the process stops and booting continues. I did not manage to touch all four corners. But all functions of the Zbitx? work when? using the web interface or keyboard, mouse and HDMI. Another issue was the delivered Micro-USB-Adapter. Now another adapter and a simple USB-Hub do the job. I have the same software as Sam and also updated Zbitx and display, but no help.
