v4.3 refuses to start up in full screen mode

[Mike Sierra]

Despite my 5760x1080 nVidia Surround setup, P3D 'prefers' to start in 1080x786 - mode (see screenshot)



Every time I have to pull out the borders to maximize the view, every time I save a startup scenario with the large view, but next time I'm again finding myself in the 1080x786-box.
WHAT CAN I DO?
With Win7 this only occasionally happened, most of the startups were correct, now with Win10 it's a nuissance!
BTW: These are my respective startup settings:

Running P3D with admin rights?

[Mike Sierra]

Alas, this is/was not the solution.
Though I start P3D via batchfile:

@Echo OFF
REM Start P3D and then wait (!) until P3D is finished...
start /WAIT "Prepar3D" "D:\Prepar3D v4\Prepar3D.exe"
REM ...before executing the further lines, quitting all addons started in dll.xml and exe.xml
taskkill /F /IM "TrackIR5.exe"
taskkill /F /IM "AS_P3Dv4.exe"
taskkill /F /IM "littlenavmap.exe"
taskkill /F /IM "AS Cloud Art.exe"
taskkill /F /IM "WhereAreMyAircraft_P3D_V4.exe"
taskkill /F /IM "SPAD.neXt.exe"

I run this batch as admin, and - which I haven't done up to now - I added the "run as admin" to the properties of the invoked prepa3d.exe file - No effect for the next time, again 1024x786...
