Update overlay doesnt show full bed

I have a LB 150 camera, using supplied usb cable. Mounted to the lid so bed is in full view when opened.

Camera calibration done, multiple times, camera allignment done, multiple times. Why when update overlay done the image is zoomed in? Ive spent most of my day trying to figure this out, re done calibration and alignments to the best i can get them. Scrolled other threads where people seem to have same issue but doesnt seem to be resovled?

I just got the camera a few weeks back and very eager to start using properly. Any tips tricks solutions on to how i can fix this? Thanks for any help.

Multi-posting the same issue in many places just gives us more work to do. Please, if you’re going to be impatient, at least do it by just bumping the previous post.
