DJI go4 says visual calibration needed but lets me fly my Mavic air .
When trying to calibrate with assistant2 it fails . I do not see the pattern on my computer monitor nor the image of the drones on my screen .
I remember it worked a couple of months ago.
What to do?

Hi there, we're sorry for any inconvenience caused. May I know the what Windows version are you using? Also, can you please try to reset your PC resolution to default and kindly make sure to use a 14 inches monitor to be able to see the pattern for the Vision System Calibration. For reference, please see the video tutorial below. Thank you.

I’m using Mac but it helped but I set my monitor on for 10 inch and disconnected the second monitor dodge the calibration worked fine thanks

Same problem.  I use a 27" iMac with my old 27" iMac connected with target mode as a second monitor.  I could get nothing but a blank screen no matter what size or resolution I put in.  

This was solved by disconnecting and powering down the second monitor.  After that, it worked fine, detected the monitor size and went right into the calibration process.  The two rear arms have to be half-folded or they get in the way during this.  NBD.
