Please help @sidbh @philip

are you using the stock QGC? and have you been changing settings?

yup I am using stock QGC and I have not changed any setting…

what camera and autopilot are connected?

pixhawk cube and jetson nano HDMI output (resolution setting 1080P) in airunit instead of camera .

ok, that sounds fair. to just test do you have something like a gopro? also you do have the cube powered as you are trying this?

yes cube is powered and I dont have any camera.
This problem is started after update of remote unit and air unit.

i will again try to update both units and check.

please let me know if this is known issue.
