None of the things you told me to do were helpful. But! You used a term "mirroring" which I did not know. For some reason I clicked on the tiny monitor icon at the top of my computer screen, and there was an option to click on"mirroring" which I did. And viola, the computer screen came up.
So I am satisfied and am willing to pay the $24.
