to everyone for their input and help, it is MOST APPRECIATED!
After reviewing the details, I decided to purchase a second identical HP monitor easily eliminating the current issues, and hopefully any future issues, when using two monitors in a variety of ways. The Samsung was just too old and not compatible, which would require work arounds (and luck) to make it perform as required, but was/is a great monitor.
Again, Thank You everyone!
Bob PS This is a GREAT service and website!
I am very pleased to have found it.
