I would like to understand how to view an Excel workbook across 2 monitors
with one instance of Excel running. I have been able to click and drag to
stretch the Excel workbook window across the 2 monitors, but then have to
manually size the window in each of the 2 monitors to be able to use this
feature. With different sized monitors, this is not too convenient.

Isn't there a better way to do this?

Thanks.
