Thanks EQ. I did find what I believe is the "fix" I need by trial and error. There is something called Miracast which I assumed was a driver missing from my Windows 10 platform.
Later, I was given to understand that Miracast is supposed to be a part of my Smart TV, Samsung, but my Smart TV is about seven years old, so I guess it did not come with it. AT least when I go throught th esteps of installation, I get the message it does not.
Now I do have the connection for watching any videos I have on my PC or photos and music. I wanted to be able to read documents liek pdf's and the like, but I will continue reading them here enlarge going off screen and moving things about a lot. It works but it does get a bit tedious.
Thank you for you kindness always. All blessing in Jesus crhist..j
I have been away from may computer for a few days so didn't get your message until now.
My guess is that you need dual video outputs on your computer. Some video cards may have these. Otherwise, if I am correct, you will need to buy a second video card for your computer.
It may be possible that there are devices that split a video signal into two. I would check newegg.com to see if they had anything. You might also try ebay. I speculate that it exists, but I am not sure what it is called.
I don't know which way would be the cheapest, but I would lean toward a second card if you can comfortably afford it.
Good luck.
