I am a second owner of nx300 with 8000 miles in 2019. Last week when I ship in reverse the screen show only 2/3 not full screen. I called AND take car to dealer and they said the smaller screen in normal but I have full screen for more than 2 years and seem like they do not believe me. Please help

 

This video shows the 2019 NX reverse camera display in action at approximately the 1 minute point:
