If you have been told that it is not possible to open two Excel files at the same time so that you can view them on dual monitors, we have some great news for you. It can be done!
Follow these steps to open two different Excel files on separate (dual) monitors (from one computer):
1. Verify that you have an Excel icon on your task bar*.
2. Open the first Excel file that you want to view.
3. Holding down the SHIFT key, LEFT-click on the Excel icon.
4. When the Excel window opens, go to the FILE tab and open the second file that you want to view.
*You can also do this if you have an Excel shortcut on your desktop. The only difference is that you will hold down the SHIFT key and RIGHT-click on the Excel shortcut.
