Laptop doesn't detect external monitor

[Philip131]

My laptop doesn't recognize an external monitor. 

I have done the following:

1. Tried three different monitors.
2. Verified that the monitors all work with other computers, either laptop or desktop.
3. checked that the monitors are on when testing if they can be recognized.
4. Tried plugging them into either type c, USB OR HDMI ports.

I go to settings - display - detect and get the message that an external monitor isn't detected.
