External monitor no signal ThinkPad P1

Question

I've used Ubuntu on my Lenovo ThinkPad P1 Gen 2 and it works fine with the internal display. When I connect an AOC monitor with hdmi, the monitor says "no signal".

• My display settings look like this:

• Command xrandr returns this:

  Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767

I noticed there is a function key that looks like a laptop with a screen beside it, which should "switch between the computer display and an external monitor" but after pressing the button multiple times nothing noticable happens and the settings and outputs remain the same.

I really just want to use multiple monitors. If you need any more info I'll be happy to provide it!

You have to press that button while holding the Fn key
