I have an interesting issue that popped up after using my system for a couple of months. I have a Plugable USB-C docking station (UD-ULTC4K) that allows me to run 3 external monitors. I run 2 HP 22er but my problem is this: The DisplayPort connected monitors only work when the laptop lid is closed. If I open the laptop, the external monitors are disconnected. I want to be able to use my laptop screen as well as the external monitors. Any ideas?
My Plugable docking station is connected via USB-A 3.1 since despite apparent compatibility, when connecting the docking station via USB-C, the laptop does not recognize it at all--no power delivery, no connection light illuminated.
Thanks for your reply, but that is not my problem. My problem is that my external monitors, connected via the docking station do not receive a signal until I close the lid to my laptop. Everything else works. It is almost like DisplayPort does not function until the laptop lid is closed. Like the Intel Iris GPU and DisplayPort drivers are mutually exclusive and cannot work at the same time. This was not always the case, but happened a few months after things were going fine. Multiple updates from HP and Windows have occured. I am completely up to date with updates.
