Tripp Lite USB C to HDMI Multiport Video Adapter Converter 4K w/USB-A Hub, USB-C PD Charging Port & Gigabit Ethernet Port, Thunderbolt 3 Compatible, USB Type C, USB Type-C (U444-06N-H4GU-C),White

Just ran into a similar dead screen issue. I was able to get control using a Tripp-Lite USB Hub with an HDMI monitor and wireless keyboard/mouse. The one I have is Model: U444-06N-H4GU-C. It's out of stock on Amazon, but something similar should work. https://www.amazon.com/Tripp-Lite-Thunderbolt-Compatible-U444-06N-H4GU-C/dp/B01LXFHGM5
