Since my partner upgraded from a MacBook (12-inch, Early 2016, macOS Mojave) to a new MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports, macOS Catalina), the three USB-C peripherals (iPhone 11, Wacom Intuos Pro Medium, Seagate Fast SSD 1TB) plugged into the three downstream USB-C ports on the back of her 21.5-inch LG UltraFine 4K Display In a nutshell, here are the steps I performed in order to get the external displays to work: (1) Reset the NVRAM with the external monitor plugged in via USB-C to HDMI cable. (2) Updated to macOS Catalina 10.15. (3) Waited for ~10 minutes, the external monitor's screen flashed, and suddenly started working.
