I started having an issue a few days ago with my P50 and an external monitor. I plugged it in and could find no option anywhere to mirror the display like it used to (so the same screen is on the laptop and the monitor). I searched for such a setting to no avail.
Tonight, I unplugged the monitor, briefly (an H233H via HDMI) to see if the laptop would fit into a laptop case that I have, and then went to plug the monitor back in. When I did, the laptop screen went dark as though the laptop went to sleep - had to press the power button and log back in (it did not shutdown) - and now the external monitor isn't detected at all. I ran system updates, and have rebooted a couple of times, and still no external monitor. It's a ghost. How do I get it back?

Thanks for reaching us for support.
We'd like to know, are there any changes/updates prior to this issue? Have you also tried using a different HDMI cable? What can you see when you were trying to connect an external monitor?
