My laptop is stuck on some mode

[Windows Central Question]

So my laptop screen is broken and I haven't fixed it yet. I connect it to my computer moniter and i use it like that. It works all and fine. I go on holiday and my little sis tries using my laptop but she couldn't make it work. I come back from holiday and try go onto my laptop. My laptop doesn't connect to my moniter and whenever a press more than a few keys it starts beebing. Also when I press alt ctrl delete it refreshes and the beebing is gone. However after pressing a few keys again the beebing starts. I think it's in some mode but I can't see anything to get out of it.

are there any keys on the keyboard for changing the project options? So you can cycle the project display options until you see duplicate?

Or: Windows Key + Shift + Left or Right: Move current Window from one monitor to another (when using a multiple monitor setup)
Windows Key + P: Project a screen
