The computer I am having issues with is a Dell XPS 15 with an Ultra HD (3840 x 2160) InfinityEdge touch screen.

I am teaching in a school. All the classrooms have projectors.

If I connect the laptop to a projector, you can see my desktop background. I am also able to show powerpoint presentations. I can also play videos when they are embedded in powerpoint.

However I cannot:

Play videos in VLC
Show my web browser
Show a word doc
and probably many more

The apps appear on my laptop screen but they will not come up on the projected screen.

Other teachers do not have this issue.

Does anyone know what the issue is here? (I suspect it might be something to do with my resolution).

It sounds like the desktop is set to extend rather than duplicate, making it effectively a computer with two screen, as opposed to just mirroring what's on your display.

when its plugged in to the projector press Windows Key + P, and select the duplicate option.
