I assume the attached pictures do not show the whole screen.
If that is the case, then I suspect the issue is on the VNCViewer side.
? Have you checked your settings on the computer you are connecting to the Pi with?
? Maybe even a simple expand the screen by dragging a corner.
What is the setup of the computer you are trying to view pi screen on?
particularly:
1. OS
2. VNC Viewer application
3. Screen resolution of the monitor in use
Second possibility is that you are not connecting to the main screen of the Pi
You still haven't provided details of the Pi you are connecting to either.
