Working on a PC with a projector?

Can I use the projector to display all processes on my PC screen (notebook) on the wall? A 1 to 1 copy? Even if I do something on the Internet?

Do you mean how you do that in Windows?

Windows key + P, then select "Duplicate" there.

Sometimes that happens automatically

Yes, with Windows 10 you just have to enter enter in Cortana and press scroll and then there's duplicate ad or display on 1 or click on this report and then you will get it yourself. Just try it 😉

Yes press "windows key + p" and select "duplicate"

Do I also see the arrow when I move the mouse?

Mom, he used the bad word with C!

You will see a copy of your screen. Ergo yes, you can also see the mouse pointer.

All right 😂
