Disable Presenter View in PowerPoint
If you are having the issue where going into presentation mode messes up your screen set up with your board, this is more than likely do to a simple setting in powerpoint. To disable this feature:
1. Open your PowerPoint presentation.
2. Go to Slide Show from the top menu bar
3. Under the Monitors section, uncheck the 'Use Presenter View' box and choose 'Primary Monitor' from the drop down above it.
After this, you should be able to present without having your screens affected. Whenever you turn off the setting here, it should apply to your other presentations as well.
