Suddenly Go4 app prompt to calibrate Vision Sensors on Start up screen. Never crash before. And Acer laptop has Windows drivers signing disabled. DJI Assistant 2 V.4.1.24 calibration screen white. So can I send my AC to DJI for repair? Is it safe to fly without calibration?

I have that same problem can not calibrate sensors either tried on 4 different comps  and have flown for almost 3 months with this warning since i don't want to be without the MA for 6 weeks or more.

Already tried uninstalled and installed DJI Assistant 2 V 1.2.24 with Windows Driver signing disabled. Still have blank white screen when trying to Calibrate. I also did  firmware 0400 re flashed without issue. Don't tell me I need to buy a New Asus laptop to Calibrate this.

Hi, Thank you for your response. Could you please try to use different PC or laptop? You can borrow that to your friends or relatives. Let's see if this will work. Thank you.

Ok found out why we can not calibrate the sensors this is the error Windows is reporting

Vision interface 3 error
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

My Air has been prompting me to calibrate sensors for a few weeks now. I have tried everything mentioned to no avail.
Also, the screen looks way different in Assistant 2 than it does in that video. Something is off here.
But, I don't sweat it. I keep obstacle avoidance turned off anyway as I find it annoying.

Did you ever find out the fix (work around for this?).  I all of a sudden started getting "Sensor Calibration Warnings" in DJI G04.  Then when I tried to run DJI Assistant I got RED WARNINGS in Windows 10 which is related to their Driver Signature.  

I finally get info on editing the correct HKEY to disable User Accounts so that DJI Assistant can be installed and actually run.  

But now when I run the DA it will not calibrate the sensors.  All other aspects of the program work.  I have downgraded my Firmware, downloaded Log files, updated geo fence, etc etc.  But the stupid Calibration does not work and I am growing very tired of this :0

Any help will be greatly appreciated.  I have a P4P.

I have tried on FW .600 and then down to .300.  Tried both DA 2.0.6 and 2.0.2.  Reset to factory defaults.  

Does this have anything to do with others having issues running Assistant in other threads?  Looks like there may be a new version out in some regions and hopefully showing up soon.  I wonder if that will fix this issue as well?

Had this isssue also and tried using different computers, resolutions and drivers, however what worked for me was to attach an external 22" monitor to My thinkpad laptop  and then used it as main monitor at my laptop and then the sensor calibration worked fine.  I have no clue why this combination worked - however, if you don't try you don't know you if you are Lucky

My problems solved by connecting to my desktop PC using DVI instead of HDMI connections to my SAMSUNG 24" LCD monitor.
