Hello again,
I found the Display adapters, when you click on this, a drop down text message says "Nvidia GeForce 210" there is no red cross near the text.
The top toolbar does show two monitor logos. When you hover the cursor over them one which has a x on it says "uninstall"
Hover over the 2nd logo and it displays "disable".
this means little to me , but I am interested to hear any comments from you.
I have to say that at hte moment I am inclined to leave things as they are, but your advice is welcome.
Thanks for your patience on this.
