360X pavilion can’t detect external monitor

HP Recommended
HP 360x pavilion 2-in-1
Microsoft Windows 10 (64-bit)

Hi, I’m having trouble getting my HP laptop to detect an external monitor. It has been working fine until now. It brings up the screen in settings > display and shows the 1 2 screens when I plug in the cable, but when I click “detect” it repeatedly states “didn’t detect another display”

I have already tried a new cable, uninstalling and reinstalling the display adaptors, shutting down and restarting, roll back to previous update on drivers, updating drivers & completed every update possible. I’ve also connected it successfully to someone else’s laptop, so clearly this is not an issue with the monitor or the cable. 

If there’s anything else I can do I’d greatly appreciate if anyone could help, I’m really at a loss of what to try next.


Thank you
