Hi,

I've been trying to calibrate my P4 in the app but at the last step at 50% it will say failed

tried it 5 times already, anyone know what causes it? purchased it a few days ago, comes with the latest firmware. Thanks

dondonsio,

You are trying to calibrate the OA sensors correct?  I had the very same problem on my desktop.  I have a dual monitor system and the monitors are more 4:3 rather than widescreen 16:9.  Anyway, every time I tried it failed in the same manner as you describe.

I moved to my laptop and performed the calibration and it went without a hitch.  I repeated several times and each time on the laptop it was successful.  Moving back to the desktop, calibration failed every time.

Do you have another computer you can try?  Also, the one thing that was recommended to me was to ensure the font was the default size and 100% zoom.

Here's my original thread with my calibration issues:

Hi Crimson, yea. hmm base on your experience it might be coz of my monitor settings, I've a 3D monitor w/ strobelight on all the time (anti flicker) @ 120hz, native resolution and 100% text. I'll try turning it off, if it doesn't work I'll try it on my laptop. Thanks a bunch!

If you figure it out let me know.  I've yet to get a successful cal on my desktop.

Successful calibrating on my laptop, tried it twice tho still no luck on my desktop. Tried 60hz and removed the strobelight. Gonna try again tomorrow, btw what monitors are you using?

They are Dell 21" monitors.  Mine are more of a 4:3 aspect rather than 16:9.  I'm thinking that may have something to do with it.

After looking at the image you posted, it looks like you're using a widescreen monitor so maybe that has no bearing.  I do run my monitors at 1600x1200 and pretty bright.  I've tried lower resolutions with no luck.  Maybe next time I'll adjust brightness.

Can you post some screen shots of the process and where you are getting the errors.

Es el firmware a la versión más reciente? ¿Es el RC ajustada en el modo P? ¿Esto sucede afuera o solo han probado dentro de su casa?

Cuántos satélites es lo que ves en la aplicación GO? Es lo que ves algún mensaje de error? Tiene que conectar la aeronave para el software Asistente 2 buscar las actualizaciones del firmware y para calibrar los sensores delanteros?

Asegúrese de que no hay polvo o huellas dactilares en las cámaras delanteras y tratar de hacer la calibración OA una vez más. ¿Está teniendo el mismo problema como dondonsio o lo hace actuar de manera diferente? ¿Ha intentado utilizar un equipo diferente? Es el firmware del avión no tripulado a la última versión?

It would be nice to see the specs/settings are of your laptop's screen compared to your desktop (which you already provided in a previous post), so that we could pinpoint what could be causing the issue.

@Crimson and DJI Jamie

I'll try to calibrate again and post the settings on both my laptop and desktop as soon as i get my P4 back (left it in my bro's house). Cheers

DJI-Jamie,  donsio and I are having the exact same issues...  Here are the configurations of my systems:

1.  Desktop - Dual Monitor Dell 21" monitors 4:3 aspect.  resolution 1600 X 1200, 60 Hz Text Size set to 100%

2.  Laptop - Single Monitor HP 8570P elitebook 16:9 aspect. resolution 1600 x 900, 40 Hz, Text Size 100%

Update:  I changed the refresh rate on my laptop to match my desktop at 60 Hz.  Phantom OA sensors still successfully calibrate on laptop and fails on desktop.  

I also tried varying the brightness on both the desktop and laptop...  make no difference in ability to calibrate OA sensors.

For clarification, what operating system do you use on your laptop and desktop? Just to rule out whether it is an issue with your monitor and not the tower itself, are you able to temporarily connect to a television screen and reattempt the calibration?

Having issues with calibrating to. Im using Windows 10 with a older computer could being a older computer be the problem?

Jamie,

I've been able to calibrate on my desktop computer at work (running windows 7) and on a laptop (running windows 10).  The only failure I get is on my personal desktop at home (running windows 7).  My monitor configuration at work is almost identical to mine at home.

I'll try to connect to a TV..  If not, I can move the DJI Assistant 2 window over to my second monitor and try to calibrate with it.  I can also bring in a third monitor and try with it as well.
UPDATE:  I didn't connect to a TV but I did the following:

1.  Attempted calibration on desktop (win7) Monitor 1 (1600x1200 - 4:3 aspect) failure.
2.  Attempted calibration on desktop (win7) Monitor 2 (1600x1200 - 4:3 aspect) failure.
3.  Attempted calibration on laptop (win10) (1600x900 - 16:9 aspect) success.
4.  Tried different resolutions on desktop but complete test pattern could not be seen on screen.
5.  Connected laptop to Monitor 2 and extended desktop from laptop onto Monitor 2.  In this configuration, using the laptop, the calibration was successful when the calibration screen was on the laptop screen.  However, when I moved the screen to monitor 2 (connected to the laptop) and performed a repeat calibration, the calibration failed.7.  Attempted calibration on WORK desktop (win7) Monitors 1 and 2 (Dell 1680X1050 - 16:10) and the Phantom calibrated successfully on both monitors.

Hi Crimson and Jaime,

Tried calibrating again on my desktop, still failed even @ 60hz. Here are my settings on the laptop and desktop
Calibration on the laptop was successful even at "aspect ratio" scaling setting

Laptop running on win8.1 x64 home, desktop on win8.1 pro x64

donsio,

Interesting that both screens have the same resolution (1920X1080).  Right now I can't see anything that would point to the issue.  I've adjusted resolution, refresh rate, brightness, contrast, etc. and can't see a pattern.  

One thing I need to try is hooking a different monitor up to my desktop and see if it calibrates.  If so, it would definitely point to something with my desktop monitors.  Especially given the fact that when I hook my desktop monitor to my laptop in a dual monitor configuration, I can get a good cal if I use the desktop screen.  But when I slide it over to the monitor and repeat it fails...

Donsio and Jaime,

I've done a little more experimentation and have come to the conclusion it's my monitors.  I don't quite know the issue with them but would be very interested in hearing your opinions.

My dual monitor configuration consists of two DELL 2007FP monitors.  From the dell site, here are the specs:
Display Type : LCD Monitor
Diagonal Size ( Viewable Size ) : 51cm (20.1") (51cm (20.1"))
Panel Type : VA - Vertical Alignment & IPS - In Plane Switching

Weight (panel only - for VESA mount) : 5.2 kg (11.5 lbs)
Weight (with packaging) : 9.6 kg (21.2 lbs)
Features : VESA® 100mm Mounting, Anti-glare with hard-coating 3H, Slim Black or Silver Bezel, Includes Height Adjustable Stand

Voltage Required : 100 to 240 VAC, 50 Hz to 60 Hz

I removed my #1 monitor and replaced with a Dell P2210T.  Again, here are the specs:

Diagonal Viewable Size:
22 inches (558.68 mm) viewable area
Aspect Ratio
Widescreen (16:10)
Panel Type:
TN - Twisted Nematic
Optimal Resolution:

Here is the display information as operating on my system:

Monitor 1:  DELL P2210T:
1680X1050, 60 Hz

Monitor 2:  DELL 2007FP
1680X1200, 60 Hz

Running the calibration with the cal window on Monitor 1 (DELL P2210T), the calibration passes, and on Monitor 2 (DELL 2007FP) the calibration fails.

Monitor 1 Cal

Monitor 1 Cal Screen

Monitor 2 Cal

Monitor 2 Cal Screen

I had a similar problem on my desktop PC, I could not overlap the red marks on the blue ones. I tried it on a laptop and the calibration has been completed successfully without problems.
