I need a tablet with a screen that is able to connect to a computer that is connected to the project screen.
The display of the computer need to come out on both the tablet and the project screen for the teacher and the audience.
The teacher needs to be able to open files like Powerpoint, websites, etc. controlling the computer with the tablet on the stage.
And then able to doodle not only in Powerpoint, but just on the screen.
Where can I purchase such a product?
