i can see one way that could probably work but only if you have win 10 Pro as its the group policy editor and its not available in home.

wonder if deleting samsung drivers will make it go away. I can't seem to find anything helpful on the internet.
I can think of big fixes like set up a new
local user, make it admin, copy contents of old user onto new, and see if the new user has same screens (probably best to do this before copying folders) but that seems a lot of work just for 1 thing. It seems odd you can't make it forget what you previously connected to it
But then windows search remembers any previously installed...
