So after fight my MMP & Windows computer for 2 days, trying every micro usb cord in my house, I finally get the MPP to connect. I refreshed all DJI drivers in my device manger. I now get through the calibration process to get a screen size error. So I enter my screen size(19 inches) try to re-calibrate it bring to to my calibration screen but it seems the vision sensors are not active. The 2 little screens on the lower left show nothing & the main(calibration) screen has NO dots or corner markers to line up. I have tried every resolution size possible that my computer will allow, with DJI Assistant restart each time, with no luck. Could someone please help me? This start as downward sensors needing calibration but now that the process wont complete I'm getting warnings for both forward & downward now. I was hope to take my MPP on vacation next week but if I cannot get this resolved that wont be happening. And advice would be greatly appreciated
