Hi there, Azkaban3000.
I see that the external display you're using with your MacBook Pro keeps disconnecting. I'm happy to help.
Use external monitors with your Mac -- Make sure you're connecting it correctly.
How to reset the System Management Controller (SMC) on your Mac -- If you're connecting the external monitor correctly, reset the System Management Controller. Follow the steps under "How to reset the SMC on Mac notebooks" for a nonremovable battery. Test the issue once you're back to the desktop.
Reset NVRAM or PRAM on your Mac -- If resetting the SMC didn't resolve the issue, reset the nonvolatile random-access memory (NVRAM) using the steps in this article.
Let me know how that goes, and take care!
