As best practice, the Instructor Workstation should be set to Extended mode for the Windows Display Settings.

Extended Mode:

Screen #1 – The Dell All-In-One PC
- Allows for “My Eyes Only” viewing of grades, teacher notes, PowerPoint Notes, etc.
Screen #2 – The Wacom Drawing Monitor Tablet
- After Sharing Screen 2 in the Webex Desktop App, any application you drag to Screen #2 will be seen by your students in class or students joining remotely.

Duplicate Mode:

Screen #2 is a duplicate of Screen #1, the Dell All-In-One PC.
You may encounter the kaleidoscope effect when you have the Webex Desktop App at the forefront while you are sharing your desktop screen.
When you go into Presentation Mode in PowerPoint, you will not have your notes.

How to change the Windows Display Settings with shortcut keys

If you find the Instructor Workstation set to Duplicate mode, you can quickly switch it back to Extended mode by holding the [Windows] key and pressing the [P] key.

Hold [Windows] key and press the [P] key.
At the pop-up, click on Extended.
Hold [Windows] key and press the [P] key once again.

If needed, reorient your screen placement.
If needed, recalibrate the Wacom Drawing tablet.
