Has anyone had any difficulty calibrating the front sensors?  I have tried multiple times and all have failed when using my regular desktop computer.  I took my Phantom 4 to work and calibrated it on the first attempt so I'm wondering if it has something to do with my computer monitors or perhaps difference in room lighting.  There is a slight difference in resolution of my monitor at home versus work (1600X1200 vs. 1680x1050).

Make sure you have the bird far enough from the monitor,  that you are able to see the birds target box on the screen as well as the app target box.
Try to be as steady and precise as possible when lining up the targets in order to get a precise calibration.

Hello, have you updated the firmware as well as the DJI assistant 2 to calibrate it again?It would be better to clean the sensing system and choose a monitor larger than 12.5' before calibration.
Here is a tutorial:

If it couldn't work, please upload the screenshot of the error message here.

The Assistant is version 01.00.0002 and the Phantom4 firmware is 01.01.0301.  I believe that is the latest on both.

All sensors are clean with no smears or smudges and the monitor is about 21" diagonal (with a 4:3 ratio).The calibration process progresses without any erros or exceptions.  The directed instructions vary a little with the tutorial.  Here are the actions I'm asked to perform:

1.  Using front sensors line up the marks from the quad with the marks on the test pattern.  These marks create a smaller box within the test area.  Once aligned the marks jump to basically the edges of the test pattern.

2.  Again, front sensors, line up the marks from the quad with the marks on the test pattern.  The marks are at the edges of the test pattern.

3.  Pivot the quad vertically, to complete the blue vertical line.


4.  Pivot the quad horizontally, to complete the blue horizontal line.

5.  Rotate the quad where the bottom sensors are facing the screen, battery oriented to the right.

6.  Repeat steps 1-5 with the bottom sensors.

I executed this without any errors and the calibration box pops up...  The progress meter counts up to 33%, pauses, jumps to 50%, pauses and then shows 100% and a failed to calibrate.

Update:  I loaded the assistant 2 software on my laptop and went through the calibration.  The quad calibrated perfectly the first time (just like on my work computer).  The issue really does seem to be with my desktop computer and not the quad itself.
Update 2:  I have tried multiple calbrations on my desktop computer and each time it fails.  However, I've calibrated twice on my laptop and each one as passed without issue.  In a sequence of three cal events I got these results:  LAPTOP-PASS, DESKTOP-FAIL, LAPTOP-PASS.

It truly looks to be an issue with the desktop setup.  I uninstalled the software and drivers and reinstalled, without success.  Calibrations still failed.

ONE THING TO NOTE:  On the laptop calibrations, at 50% progess, the software seems to pause longer before it jumps to 100% and passed calibration.  On the desktop, when progress gets to 50%, it displays 50% progress for just a second and then jumps to 100% and gives the failed cal error.

Have you changed the display scale ever before? For the sensor calibration, the display scale should be 100%. For example , if you have adjust it to 150%, the calibration will fail at last
