Setting output size in Articulate Replay?

I'm having the issue above as well.  Windows 10 operating system, I've changed the screen resolution multiple times and DPi to 100%.  There is no way to get Replay to capture only the area you would like it to capture, and even if you do, sometimes your mouse clicks don't match up.  I've also been looking through conversations about this issue starting three years ago.  How can there be no resolution to this issue in that amount of time?  You have to expect that users will work from multiple displays when recording content.  Many of us follow a script when recording material.  Please resolve this issue, or have a better way of communicating settings that need to be adhered to in order for your application to work!
