Hello and good day. I am sorry to read and to know that you are having issues in calibrating the vision sensors of your DJI drone and thank you for reaching out.  With regards to issue that we are facing today, you may give a try to change the resolution of your screen for your reference you may take a look at this information. It is recommended to use a monitor with a size of 14 inches or more, and a curved screen is not supposed to be used. Set the display resolution to the recommended value ( usually 14 inches for 1366*768 or 1440*900; 17 inches for 1366*768 or 1280*720; 19 inches for 1366*768 or 1440*900; 22 inches for 1680) *1050 or 1920*1080; 24 inches for 1920*1080 or 1920*1200 ). Please give us an update further assistance. Thank you.

thanks for the reply - I am using an iMac with a 21.5" screen - not curved - didn't double check the resolution but its a 4K monitor - I have calibrated the P4 on the machine before - as I said one of two things happen - either the screen message or the progress bar stops at 85% - stumped
