Thank you for the reply.
You mention Word and Power Point in your answer and based on your details I am not certain you and I are on the same page. Let me give a bit more detail. For both home and work I have two monitors side by side. I have my desktop setup that it stretches (is
extended) across both. I can take a word or power point document and stretch it across both monitors so that I have half the document on the left (1st monitor) and half of it on the right (2nd monitor).
I cannot take a Lync application that is showing a shared desktop (no matter what size the source is) and stretch past the width of the first monitor. For that matter I cannot do this if I start the process on the second monitor.
Does that help describe the problem?
Now if you did understand the problem, and your last line is suggesting that this is indeed expected behavior... then I hope someone has submitted a change request or request for enhancement!!
