Which screen is black depends on my display settings: I've gotten this to happen with both screens. Previous users have mentioned using the recommended drivers. Interestingly, the driver manager didn't come with my mint installation (20.1 Ulyssa). When I installed and ran it, it simply states "Your computer does not need any additional drivers."
How can I fix this so that my desktop is visible on both screens?
