Camera green screen

I have a Lightburn camera 8mp with an 85 degree lens. I can only see the very top of the screen, 10% with flickering, when I try to calibrate. I did see the post on flickering and no changes happened when changed light source.

I am new but putting in a lot of effort. Thank You for any assistance.

I’m not sure where the question is here Robert…

What does this mean?

When I check camera with a computer without lightburn the pictures are clear. These pictures jump as if there is some type of interference. I am in desperate need of help because i have several different production cuts I would like lined up and not keep opening lid after each project AF2440.
