Its prompted to do the calibration.... Vision sensor calibrationWere you prompted to do a calibration? The manual states only do a calibration if prompted to do so. I think that some folks decided to calibrate "everything" out of the box, and that may be where some issues arise for them.
What type of calibration are you attempting?
I tried on laptop and also in desktop pcNow I have heard that some/a few folks had trouble doing that, but when they went to another monitor it seemed to help and complete the process
Are you using a laptop/notebook, or a std. pc lcd display?
