I’ve created a thread for anyone interested in this kind of thing
I can put some thoughts / questions out there and see what comes back (if anything comes back )
interesting thing, I found that the monitor image was slightly too big for the screen it meant that I couldn’t quite see what was going on top/bottom
I discovered an icon “lx terminal”, this appears to be the same as getting into the cmd function on a windows machine eg you get into a dos type display and you can type in commands to the machine eg ipconfig
anyway
so first I typed raspi-config to see what it would do
it suggested try sudo raspi-config and then took me straight into the menu screen, I then enabled overscan , rebooted and the screen is a little smaller but now manageable.
the lx screen must be how you access stuff in the raspi pi when you are in GUI mode
