Windows display settings
Changing your display settings:
Duplicate (use rarely if needed): this means that your screen is THE SAME as what the kids see. This is good for typing notes together, exploring websites, working directly with students the whole time.
Use this icon on your desktop to duplicate (Clone) your display onto the projector screen.
Extend (recommended 99% of the time) - this means that your screen is DIFFERENT than what the kids see. This is great for showing videos, showing notes etc. This will allow you to take attendance or view email privately.
Use this icon on your desktop to go back to the default extended display mode.
