Hello Mike,
Thank you for your message.
Please try switching your View Mode to
Stretch - this will stretch or shrink the remote screen to fit your Viewer screen. You can switch the View mode in the
Connection Properties -> Mode tab or you can easily switch it using the
Toolbar in the Full Control and View mode as well.
In addition, please make sure that both of your Host and Viewer are
updated to the most recent version 7.6.2.0.
Let us know if this helps.
